Foreword
The participation of the
Jamaican Caves Organisation in the Parks in Peril Project began in late 2001.
Dr. S. Koenig, of the Windsor Research Centre, invited R. S. Stewart to assist
in preparatory work on the caves component of the PiP Project, then in its
nascent stages. Although there was not yet any actual funding for the caves
component, a team that was made up of Susan Koenig, Stefan Stewart, and Martel
Taylor carried out fieldwork in February of 2002 that would begin the process
of establishing a methodology for the systematic assessment of Jamaican caves.
In June 2002, funding
supplied by the sponsor of the project, The Nature Conservancy, enabled further
fieldwork, this time under the guidance of G. O. Graening of The Nature
Conservancy - USA. With the assistance of Koenig, Stewart, and Taylor, a number
of caves were visited, and good progress was made.
In August of 2002, with the
intention of assembling a group of volunteers who could carry out speleological
research in Jamaica, with or without funding, the Jamaican Caves Organisation
was founded by Stewart. The initial membership of the JCO consisted of a small
group of people who had been exploring the caves of the island with Stewart
since the early 1990's, but new members were soon added. One of the more
important of the early additions to the team was Ivor Conolley.
In the autumn of 2002, using
methods established earlier in the year, the JCO began a systematic
investigation of the caves of Jamaica.
During 2003, under the
guidance of Stewart, the JCO continued to visit and assess caves using the
activities of 2002 as a template for our own studies. Ongoing collaboration
with Dr. S. Koenig and Dr. D. McFarlane refined the biological and
palaeontological indicators that were noted in the course of the
investigations.
In 2004, the JCO began an
assessment project of the caves of St James under a permit issued to Stewart by
the National Environment and Planning Agency (NEPA). This was based on the
early Parks in Peril work, but had been expanded upon because of lessons learned
during 2003. There was no funding other than what the JCO could supply, but
with the help of volunteers, principally I. C. Conolley, M. Taylor, M.
Bellinger, E. Slack, and D. K. Roggy, over 60 caves in the parish were visited
and systematically investigated.
In August of 2004, the JCO
was contacted by The Nature Conservancy - Jamaica with regard to carrying out
the caves component of the Parks in Peril Project. A proposal was submitted,
and we received a positive response.
In late 2004, Mr. Stewart
applied for an extended permit from NEPA, which would include sampling of
undescribed cave-adapted invertebrates. This was done in collaboration with Dr.
S. Peck, and Dr. S. Koenig. The work in St James was not finished, but we
anticipated that it would be done by mid-year, and it would then be necessary
to move on to a new parish, St Ann. Accordingly, the application area was
extended beyond the original perimeter of the 2004 permit. In addition, in
hopes that the proposal submitted to TNC-J would be successful, permission was
sought from NEPA to include all of the caves located within the Cockpit Country
ring-road.
In late January 2005, within
the course of several days, the JCO was informed by TNC-J that our proposal had
been accepted and Mr. Stewart was informed by NEPA that his 2005 research
permit had been approved. Planning then began for our work in the Cockpit
Country. It was determined that two expeditions, totalling five weeks, would be
necessary to accomplish what was intended.
In late March and early April
2005, two weeks were spent in the field, and then a further three weeks in May.
Over the course of the following three months, the data was assembled into a
filterable spreadsheet using Excel, and this report was compiled. This brings
us to the time of the writing of this account, and the completion of our work.
We would like to thank the
following individuals for their great assistance in this project: Dr. S. E.
Koenig, Dr. D. A. McFarlane, Dr. S. Peck, Dr. C. Schubart, Dr. A. G. Fincham,
A. Donaldson, I. C. Conolley, D. K. Roggy, E. Slack, M. Bellinger, M. Loftin,
M. Taylor, A. Hyde, G. van Rentergem, M. Newman, Dr. D. Lee, M. Silvera, A.
Silvera, B. Gottgens, M. Phillips, K. John, P. Bailey, D. Williams, Colonel
Peddie, L. Grey, B. Hill, R. Schoburgh, M. Campbell, Joeanne and Hortense.
We would also like to thank
the people of Windsor, Rock Spring, Troy, Balaclava, Thornton, Quick Step,
Accompong Town, and Schaw Castle for allowing us to wander through your yards
and farms as we searched for caves, and for assisting us in finding them when
you could.
Most importantly, we must
thank The Nature Conservancy for the funding that made this work possible. We
hope that our endeavours will prove to be of longstanding worth.
It has been our goal in this
project to supply comprehensive baseline data for the Cockpit Country caves in
the year 2005, and we have worked long and hard at this. Although we hope that
the conclusions and recommendations that we have also included in the report
might assist in the preservation of the caves of the Cockpit Country, it is our
belief that if nothing else has been accomplished by our efforts, we will have
at least allowed those in the future to see what has changed.

Introduction
1.1.
Project Summary
1.1.1.
As part of TNC’s Conservation Project Planning process in FY04-5, caves
and their biota were identified as important and sensitive elements of the
Cockpit Country biodiversity, likely to require special conservation measures.
In order to assess the need for conservation of cave ecosystems, TNC decided to
develop an inventory of caves for the Cockpit Country. This would support the
development and implementation of a Cockpit Country Biodiversity Management
Plan that will be integrated into the Forestry Department’s Forest Management
Plan. Another related activity would be to help TNC-J to work with the
Government of Jamaica to develop and adopt a national policy for conservation
of caves and their biodiversity.
1.1.2.
The JCO, in response to a request by TNC-J to submit a plan that would
accomplish the above goals, proposed an inventory and assessment that would
examine the status, distribution, importance, condition (including threats) and
conservation needs for the caves of the Cockpit Country, in order to identify short
and long-term research and conservation needs, and to make the information
available for use through a searchable database.
1.1.3.
The target-list for the proposed inventory included those caves in the
area enclosed by the Cockpit Country ring-road that were deemed to meet the
project criteria, and several of the many simple shafts. The criteria for
exclusion or inclusion in the project will be found in section 1.3 of this
report.
1.2.1.
TNC-J Requirement: Design a format for a database of information on
Cockpit Country caves. This will be based on the Jamaica Caves Organization’s
existing database developed in conjunction with the National Planning and Environment
Agency. It will include the physical, biological, social, economic and cultural
aspects of caves necessary to determining their importance for biodiversity
conservation and monitoring changes over time.
1.2.1.1.
JCO Activity: Our existing database was expanded to include additional
factors and observations suited to the needs of TNC-Jamaica. The added columns
included: Positional data in both Jamaican datums, JAD69 and JAD2001, in
addition to the obtained WGS84 GPS-georeferenced positions; presence or absence
of the top-level invertebrate predator group, the Araneae; presence of absence
of the predaceous fly larvae, Neoditomyia farri; and the presence or absence of
archaeological resources.
1.2.2.
TNC-J Requirement: Conduct fieldwork to assess Cockpit Country caves.
For the purposes of this project, the Cockpit Country is defined as the area
bounded by the ring road.
1.2.2.1.
JCO Activity: Members of our group carried out the necessary fieldwork
in two sessions of 2-3 weeks each. A total of 29 days were spent in the field, with
the team based for several days at a time in Windsor, Rock Spring, Quick Step,
and Accompong Town. These bases were selected to enable most of our targets to
be within a one-hour drive/hike. The schedule was flexible depending on
conditions, i.e. we took advantage of opportunities to increase our output,
even when this caused us to depart from our original schedule.
1.2.3.
TNC-J Requirement: Collate existing and new information on caves into
the database
1.2.3.1.
JCO Activity: Existing databases, i.e. Fincham, JCO, were used to
supplement and verify new data that were obtained during the project. The
finished database, Appendix A, contains known information for all of the known
caves of the Cockpit Country, as defined by the ring road. It should be noted
that several new caves were added to the original list, during the project, due
to discoveries while in the field; in this report they are designated with a
double asterisk, **.
1.2.4.
TNC-J Requirement: Produce a report identifying the priorities for cave
conservation in the Cockpit Country. This will include recommendations for
monitoring selected caves.
1.2.4.1.
JCO Activity: We have done this further in the report, found under
Conclusions. Filtering of the finished database has suggested particular
patterns of degradation, and the associated causes. It has also identified
those caves that remain relatively pristine, and most in need of protection. We
have compiled a list of caves that span a range of levels of degradation and
propose that these be considered as candidates for long-term monitoring. We
have also described methods for conducting the monitoring that will have a
minimum impact on the studied sites.
1.3.
Excluded Sites
1.3.1.
The database of Cockpit Country caves that TNC had when we submitted
our proposal is based upon the book "Jamaica Underground" (referred
to as "JU" in the rest of this report) by Alan G. Fincham. In
creating this book, Dr. Fincham did a very thorough job of listing all of the
karstic sites that had been mentioned in the literature available to him. These
included impenetrable sinks and risings, possible duplicates of caves known by
other names, and the many simple shafts found around the island. It was
apparent to us when we wrote our proposal that of the approximately 135 sites
listed to be within the ring-road, a number of the sites were either not true
caves, or were lost/un-findable. Many were also simple shafts, of no great
depth, that were entirely in the twilight zone (thereby supplying no habitat
for troglobitic species), with no suitable roosting space for bats, and no
hydrological activity other than the occasional taking of water from the
surrounding hills in rainy times. To include all of the JU sites, it would have
been necessary to spend several months in the field in an attempt to find caves
that were possible duplicate entries (and didn't exist in the first place), and
in the case of simple shafts, descending with vertical gear into pits that had
nothing but boulder chokes at the bottom and a few terrestrial species that had
either fallen or crawled in. Not only did the available funding not allow this
expenditure of time, much of it would have been either futile or pointless.
Therefore, one of the first things we did before submitting the proposal was to
filter out the sites that did not seem worthy of the investment of our time.
This gleaning resulted in approximately 70 caves deemed suitable for the PiP
Project. In the course of the fieldwork, most, but not all, were located, but
the addition of several new sites brought the total to 87. This number includes
several shafts that were also covered in detail, the most notable of these,
Minocal's Glory Hole.
1.3.2.
To satisfy the requirements of the project, we also included entries in
the database for the excluded sites, but the information is limited to what is
available in JU, along with our best guess on how to find and access them.
1.3.3.
To summarize the above: The sites that were "Excluded"
were those not visited by us, but the database does present the available
information. The sites that were "Included" are those that we
have personally investigated, and georeferenced, and have received a much more
thorough treatment. We have made the difference clear between the two groups,
and filterable, in Column B of the database, with the exclusion criteria
appearing in Columns Q-S. Several caves that we hoped to find, but did not, are
listed in Column B as "Not-found".
1.4.

Methods
2.1.
Indicators
2.1.1.
Collaboration that involved the author of this report and several
others (principally GO Graening, SE Koenig, and DA McFarlane, as described in
the Forward) began in 2002 on an assessment process for conducting an inventory
of the caves of Jamaica.
It was recognized
early that it would not be possible to conduct a thorough examination of every
cave, in every field of interest. That is to say, to determine all of the bat
species would require several nights of netting; to determine every troglobitic
or troglophilic species would require a couple of days to sample them (and many
afterwards identifying them all); to determine the definite presence of
palaeontological resources, it would take time to dig and sift in the material
on the floor, or break apart breccia on chamber walls. Not only was the amount
of time necessary impractical when faced with a great number of caves, the
approach seemed more intrusive than circumspect. The solution arrived at was to
identify certain indicators of biological, or palaeontological resources, that
could quickly and easily be determined, and note primarily these. Other
particular species that could be identified in the field would also be noted,
but we would not carry out collection unless unidentified species of obvious
interest were encountered serendipitously. If fossils were observed, they would
be noted, but otherwise we would look only for breccia and floor deposits with
potential, and would not disturb what had been found. With the addition of Mr.
Conolley to the team, and his knowledge of Taino artefacts gained by his studies
at UWI, we were able to include indicators of Amerindian use.
It was apparent
to us that it would be necessary to note signs of obvious degradation, such as
siltation, disturbance of bat-roosts due to guano extraction, speleothem
damage, garbage, and graffiti; from the beginning, entries were included on our
field sheets for these, along with room for comments. The degree of visitation
would also be noted, along with any public facilities, or specific local use.
We will describe the data values used to record these conditions in the
introduction to Appendix A.
It would also be
necessary to record the hydrological conditions of the visited sites,
specifically whether they were sinks, risings, both, or dry. If they were
indeed hydrologically active, we would record to what degree during the time of
our visit. We will discuss our method for describing these conditions in the
introduction to Appendix A.
2.1.2.
We will describe below in detail the indicators that were chosen, and
the rationale for their inclusion. Data points not discussed in this section
will be addressed in the introduction to Appendix A.
2.1.2.1.
VEGETATION/LAND-USE AT CAVE ENTRANCE: The flora and fauna immediately
outside of the cave are directly related to the occurrence of species found
within that are troglophiles, or that use caves opportunistically. In addition
to the biological importance of the land-use at the entrance, siltation becomes
a factor in degradation when the flow of water into a cave is directly across
cultivated land. (This is to be expected, but by noting land-use, along with
degrees of siltation, we have been able to make the association more definite
than our previous anecdotal evidence). The use of this indicator was suggested
by Graening and Koenig.
We have used the
following designations for land-use:
Forest - Land
that is primarily old-growth forest, with logging having been selective. Full
canopy.
Bush - Land that
has been heavily logged in the past, but was never cleared, and consists
primarily of secondary-growth forest. Partial canopy.
Scrub - Land that
was completely cleared for agriculture, or pasture, in the past, but is now in
a state of partial re-growth. Characterized by shrubs and invasive ferns. No
canopy.
Meadow - Seasonal
flood-lands that are located in cockpit bottoms. Forest growth is prevented by
regular inundation. No canopy.
Pasture -
Agricultural land that is not cultivated, but regularly grazed by livestock. No
canopy.
Farm - Land that
now, or in the recent past, is under cultivation. Ground cover is minimal other
than crops. The majority of the soil is not bound by roots. No canopy.
2.1.2.2.
VEGETATION/LAND-USE IN GENERAL LOCALE: The flora and fauna of the
extended area outside of a cave are directly related to the species of bats
that might be found in it. Different species require different food sources.
Knowing if a cave is located in a district that is primarily farming, or
primarily bush, forest, or somewhere in between, indicates the potential for
finding any particular species in it. Our criteria for land-use is as found in
the section above. The use of this indicator was suggested by Graening and
Koenig.
2.1.2.3.
PERCENTAGE OF CAVE IN DARK ZONE: Of the listed sites, some are entirely
in the twilight zone (the area in a cave where light penetrates at some point
during the day), and some are in constant darkness other than near the
entrance. The well-lit caves are usually shelter caves to one degree or
another, and they are listed for palaeo or cultural reasons.
The biota of a
cave is dependent on certain factors, and an important one of these is the
amount of light present. That is to say, cave-adapted species will not be found
in caves that have no dark-zone, and species of bats that are not light
tolerant will also be absent. By filtering out caves that have no dark-zone,
you remove those sites that will not have troglobitic species, and not house
certain species of bats.
We have given the
dark-zone area as a percentage. This value is estimated, but gives a good
indication of what is found. The use of this indicator was suggested by
Graening and Koenig.
2.1.2.4.
HUMIDITY: The humidity of a cave is associated with what might be
living in it. We did not have an accurate way to measure this, but were able to
record whether caves were Dry (ambient humidity of the area outside of
the cave), Semi-humid (not outside ambient, but less than 100%), or Humid
(100% humidity, evidenced by floating water droplets seen in the beams of our
headlamps). The use of this indicator was suggested by Graening and Koenig.
2.1.2.5.
TEMPERATURE: Again, we did not measure this, but have noted it as Cool
(the common temperature found in deep Jamaican caves which we have measured in
the past to be close to 20 C), Warm (greater than 20 C but not at
outside ambient), and Hot (outside ambient). The use of this indicator
was suggested by Graening and Koenig.
2.1.2.6.
BAT NUMBERS: This records the approximate number of bats, if any, that
were observed in each cave during the time of our visit. We did not attempt to
do anything but give a rough approximation. Our values were: None, <100,
<500, >500, >5000. This is crude, but it gives a good idea of whether
there are just a few, a small population, a medium sized population, or a large
colony of probably mixed species.
2.1.2.7.
NUMBER OF BAT SPECIES: Without netting, it is difficult to know what species
of bats are present in a cave. However, the fruit-bat Artibeus jamaicensis is
the most light-tolerant species, and is the one most commonly found in caves
that have no dark-zone roosting-space. With this indicator, we separate minor
Artibeus roosts from those that might be of more interest, i.e. those that
contain other Chiropteran species. Our values were kept simple: N/A (indicating
that there were no bats), 1 (A. jamaicensis), and >1 (roosts with
mixed species of bats). The use of this indicator was suggested by Koenig.
2.1.2.8.
BAT LOCATION: The values were dark-zone, twilight-zone, or both. This
indicator serves to reinforce the possibility of the cave having bat colonies
with mixed species. The use of this indicator was suggested by Koenig.
2.1.2.9.
BAT OCCUPANCY OF SUITABLE SPACE: This value is expressed as a
percentage and is an estimate. It was determined by examining the ceilings of
chambers for bell-holes and pockets that should supply suitable roosting space
and estimating to what extent these were being used during the time of our
visit. The use of this indicator was suggested by Koenig.
2.1.2.10.
GUANO DEPOSITS: The presence of certain invertebrates in caves is
correlated to the presence of bat guano deposits. In addition to the biological
significance, deep undisturbed deposits contain valuable palaeoclimatic
records. We have attempted to describe the condition of guano, when present, in
some detail in our assessment. The introduction to Appendix A will address this
further. The use of this indicator was suggested by Graening and Koenig.
2.1.2.11.
AMERICAN COCKROACH (Periplaneta americana): The American
Cockroach is an introduced species that has become abundant in some caves. It
is very good at what it does, which is scavenging, and it has out-competed most
other invertebrate scavengers that it has come up against. The effect of this
is two-fold: the native scavenging species that were not able to get to the
food first starved to death (P. americana move very quickly); some of
the species that were out-competed, and eradicated by the roaches, served as
food for cave-adapted invert predators that then lost their prey. The result is
that caves that have had P. americana introduced have seen a great loss
of their original biodiversity. This problem will be addressed in more detail later
in this report under Conclusions. Here, we will just give the values we used
for recording their presence: None (none seen), Some (a few, but less than 1
per 10 square metres of surface area), Many (1 to 100 per square metre),
Undetermined (for various reasons, we don't know). The use of this indicator
was suggested by Stewart.
2.1.2.12.
AMBLYPYGID: Species of this Order, in the Genus Phrynus, are one
of the top predators in a pristine Jamaican cave. The presence of a predator
gives a good indication of the presence of other species lower on the food
chain. There are at least two species of Phrynus found in Jamaican caves, and
because they are relatively large, they were chosen as an easily observed
indicator of the general biological health of the cave. The use of this
indicator was suggested by Graening.
2.1.2.13.
NEODITOMYIA FARRI: This species is usually seen in its larval form,
when it creates hanging threads, somewhat like a spider, to catch and eat small
flying insects (usually Diptera). They are a predator that feeds on different
species than Amblypygids, and were included for the same reason as the
Amblypygids. The use of this indicator originated with Stewart.
2.1.2.14.
ARANEAE: Cave-adapted Spiders are a well-represented Order in
biologically diverse Jamaican caves. They are a predator, as are the preceding
two indicators, and were chosen for this reason. When possible, we have
identified species, but when not we have simply given the number of different
species observed. This has been limited to cave-adapted species, determined by
body morphology. The use of this indicator originated with Graening.
2.1.2.15.
SESARMA VERLEYI: This is the most common of the crab species found in
Jamaican caves and a true stygobite. Two other species are occasionally found
in Cockpit Country caves, S. windsor, and S. fossarum, and we
have noted their presence in the database when these were found, but we have
made S. verleyi the main indicator for stygobites, because if they are
not present, it cannot be expected that other stygobites will be found. The use
of this indicator originated with Stewart.
2.1.2.16.
ELEUTHERODACTYLUS CUNDALLI: This is a very particular frog that bears
its young in the outer sections of Jamaican caves. It is a fascinating species,
and information will be easily found for it by searching the Internet. It is
not a troglobite, and forages outside of the caves at night. We have included
it as an indicator of the health of the connectivity between the outside, and
inside, of the cave entrances. When the land outside of caves is greatly
disturbed, such as by farming, the presence of this species will be greatly
affected. The use of this indicator originated with Koenig.
2.1.2.17.
UVAROVIELLA CAVICOLA: This is the common Jamaican Cave Cricket. They
are not found in every cave, only in those that supply habitat for other trog
species. It gives a good indication of the presence of associated invert
species, and is easy to observe. The use of this indicator originated with
Stewart.
2.1.2.18.
PALAEO RESOURCES: For the PiP Project, this primarily indicated the
presence of bone breccia. We noted this only when it seemed to have real
potential, based upon what we have learned from Dr. McFarlane. Only old hard
material was listed; soft, younger deposits were not. The use of this indicator
originated with McFarlane.
2.1.2.19.
ARCHAEO RESOURCES: Taino sites that were found by us to have
petroglyphs and potsherds have been noted. No sites with pictograms were found
in the project area. No excavations were carried out, but there could be
potential for this in the sites we have listed as Amerindian. The use of this
indicator originated with Conolley.
2.1.2.20.
VISITORS PER YEAR: The degree of visitation has a great effect on a
cave. We attempted to determine through observation and inquiry how often every
cave was being visited by humans. The number given is an estimate, but will
give a good indication of whether the cave is generally left alone, visited
occasionally, or visited often. The values used are: 0, <50, or >50, per
year. The use of this indicator originated with Koenig.
2.1.2.21.
VULNERABILITY: This entry is somewhat subjective, and has been derived
by way of criteria that will be explained in both the introduction to Appendix
A, and Conclusions (section 4.4). The values are Low, Medium, and
High. The use of this indicator was suggested by Graening and Koenig.
2.2.
Georeferencing
2.2.1.
The primary reference source for the caves of the island is the book,
Jamaica Underground, by Alan G Fincham. This marvellous work presents not only
his own discoveries, but also those of all who preceded him. It offers a wealth
of valuable information, in an easily accessible form. Unfortunately, any who
have used the given coordinates to search for caves have soon become aware of
the varying accuracy of the quoted positions. This is through no fault of Dr.
Fincham, as he was the conduit for, not the originator of, most of the
positional data, and it is not surprising in the first place that poor
accuracies would be the case, for every single entry describes visits made
prior to the removal of Selective Availability from the Global Positioning
System in May of 2000, and the vast majority took place before the GPS even
existed. Locations for caves were determined afterwards, by the use of
topographical maps. In districts such as the Cockpit Country, this can be a
confusing endeavour. As a result, the errors are commonly on the order of
several hundred metres, and at times over a kilometre. It can be easily
imagined how difficult it is to find a small cave entrance, in a large tropical
bush, which has a position with an accuracy of plus/minus hundreds of metres.
If the cave is well-known, and is listed with its local name, one merely asks
the people of the district; if it is something that was found by a visiting
speleo team, in the bush, where no one lives, and given a name that no one who lives
there has ever heard, it is difficult to find it without many hours of
searching. Then, of course, if one also finds several unlisted caves in the
process, it is difficult to know which was the originally listed site.
Being very aware
of this situation, the author of this report first attempted to take advantage
of GPS technology in the late 1990's, but the error introduced by SA would
result in positional drifts of more than 100m for a stationary receiver in the
course of 20 minutes, and it was found to be of limited use. In May of 2000,
the SA was suddenly removed, and GPS became of immediate value in nailing down
which cave was which. In the future, we would at times be uncertain as to what
JU listed cave we had found, but we would at least be able to plot it on a map
in a way that would allow it to be found again by anyone, with certainty, and
we had the WGS84 positions that could be used in any GPS receiver. When WAAS
became available two years later (described below), we accordingly upgraded our
GPS gear to take advantage of this.
2.2.2.
Positional information for the PiP Project was obtained with a Garmin
GPS76 GPS receiver, WAAS-enabled, used in most cases with an external antenna.
Intermittent problems with the antenna were encountered during the first
expedition, causing us to have to rely on the internal antenna at times, but
this was sorted out entirely for the second, longer expedition. Nevertheless,
the receiver itself remained in good working order the entire time, and at
those times when the external antenna was out of commission, we surveyed to an
open point where a satisfactory position could be obtained with the internal
antenna, and then calculated the true entrance coordinates afterwards using the
survey vector that had been recorded. (Problems of this nature are rather
unavoidable when using electronic equipment in the extreme conditions involved
with caving. Although the GPS and antenna are stored in a dry-bag during our
time in caves, they are being beaten around nonetheless. When in use in the
bush, outside of the caves, the cable to the antenna is invariably catching on
things and getting strained at the connection to the receiver. Organisations
with suitable financial resources would be expected to have two full sets of
GPS gear, but unfortunately, the JCO cannot afford this).
2.2.3.
The accuracy of the received positions varies according to several
parameters. These include: the number of satellites being received; the
trigonometric spread of the satellites; and ionospheric disturbance. We will address
these in more detail below.
2.2.3.1.
It is necessary to receive signals from at least three satellites to
establish a horizontal position. Four or more satellites allow 3D positions
(i.e. including altitude). As would be expected, the accuracy increases as more
satellites are received, with a maximum of 12 possible on the Garmin GPS76. It
is rare that as many as 12 satellites would be received, and in fact the JCO
has only one cave position with that number out of the over 200 positions that
we have obtained since May 2000. A reasonable number of satellites needed to
obtain an accuracy of better than +/- 5m would be 6 to 8, depending on the
trigonometric spread.
2.2.3.2.
The GPS system uses triangulation to establish a position on the
Earth's surface, and the accuracy of the technique increases as the angular
spread of the received satellites increases. The GPS constellation consists of
24 satellites in orbits that cause them to vary their apparent location as time
passes (unlike the WAAS satellite described below which stays in one fixed
point in the sky). At any given time, all of the visible satellites may be
grouped in one part of the sky (as seen from a cockpit), or they may be spread
out. If it is the latter case, four available satellites can give an accuracy as
good as five that are more closely grouped.
2.2.3.3.
The last factor, varying transmission signal paths due to ionospheric
disturbance, is greatly mitigated by the use of the Wide Area Augmentation
System, WAAS, which supplies corrections determined by ground-station
monitoring that are transmitted from a dedicated geosynchronous satellite over
the Atlantic. Because there is only one satellite available to receive this
from, and it is in a geosynchronous orbit that causes it to orbit at the same
rate as the Earth's rotation, making it stay at the same point in the sky, WAAS
reception is very dependent on the surrounding topography. A location in a deep
cockpit, that has hills blocking the signal from all parts of it, will not have
WAAS corrections available. When it is available, sub-metre accuracy is
possible with the reception of eight or more satellites.
2.2.3.4.
Accuracy can be increased with "averaging", which simply
involves letting the GPS receiver run for a certain amount of time, and then
plotting the position in the middle of the track-drift. Over the course of 5-10
minutes, while in a fixed location, the apparent position will drift back and
forth, as accuracy varies. Given enough time, it will describe the true
location, which will be found in the middle of the drift, and this is where the
waypoint will be taken (done by using the cursors in most receivers).
2.2.3.5.
When the location of the desired position does not allow suitable
satellite reception (such as a cave entrance under an overhanging cliff), it is
necessary to find a point further away, where reception is improved, and then
survey between the two points (this can often be done with only one survey
leg). For this reason, it is important to have a good quality compass (we use a
Brunton Eclipse), and a survey tape. Magnetic deviation must be taken into
account when using the compass, especially with long survey legs.
2.2.4.
We recorded GPS reception details on our field sheets that would allow
us to supply a rough indication of the reliability of the coordinates that were
obtained while carrying out our fieldwork on the PiP Project. This consisted of
WAAS availability, and total satellite number, along with comments on how
stable the position was when averaging. We have done this in the past, and have
been able to determine approximate degrees of accuracy on subsequent return
visits to cave entrances. It is not foolproof, but generally gives a good
indication of how trustworthy the position is.
2.2.5.
We have included our estimate of the accuracy of every
GPS-georeferenced position in both the database and this report, although the
reception information only appears in the database. We have been somewhat
conservative in our estimates and some positions quoted as +/- 15m might be
much better than this. We have generally limited our estimates of +/- 5m to
those where we had 7 or more satellites in view, WAAS available, and a position
that repeated almost exactly when the GPS was turned off and then turned back
on to check again. We must note that this technique of checking twice, with the
receiver turned off in between, was used as often as possible to ensure that
there were no gross errors. A further check on the trustworthiness of the
positions was done by plotting them on the topo maps afterwards, and comparing
them to our recollection of the topography.
Although we
believe that most of the supplied coordinates have accuracies to within the
stated allowances, it must be noted that we recorded over 100 positions during
the project and we have little doubt that a few of them might turn out to be
less accurate than we thought. We encourage all who use the supplied positional
data to inform us when gross errors are encountered. We suggest that the
techniques described above for improving accuracy be used to ensure that our
original data was indeed in error.
2.3.
Datum transformations
2.3.1.
All of the original positional data is in the geodetic GPS datum,
WGS84. In this report, and the database, these coordinates are the most
accurate. We have given them only in latitude and longitude, because most GPS receivers
will convert on the fly to the other WGS84 coordinate system commonly used,
which is UTM. For the sake of users of maps referenced to one of the two main
Jamaican datums, these being JAD69 and JAD2001, we have used Geotrans to
convert the original WGS84 coordinates into these systems. They will be found
in both the report and the database.
2.3.2.
There are several versions of the JAD69 datum parameters in existence.
In fact, the datum was never accurately defined before its recent abandonment
in favour of JAD2001. We have chosen to use the parameters defined by Newsome
and Harvey for transformations. These, along with a walk-through of the WGS84 -
JAD69 datum transform will be found below.
2.3.2.1.
JAD69 is based on a non-geocentric Clarke ellipsoid established in 1866
that in Jamaica differs from WGS84 by hundreds of metres. The datum shift
causes the natural origin of the Jamaica Metre Grid, 18º N, 77º W, to be
situated apx. 311 metres to the NNE of what a GPS will call the same latitude
and longitude. In short, the latitudes and longitudes found on the Jamaican
topos must be converted to WGS84, or the GPS datum must be user-defined to
JAD69, to have the two agree. At this time, no handheld GPS units include JAD69
in the datum list and the user-defined datum parameters are poorly defined.
2.3.2.2.
The following parameters have been used in all JCO JAD69 datum
transforms. We believe these to be the most accurate of the three sets that we
possess. For our own purposes, we have designated it JAD69_3. The ellipsoid is
Clarke 1866. The parameters are: dx 65.33 +/- 0.96 m, dy 212.46 +/- 1.49 m, dz
387.63 +/-0.69 m (published by Mugnier from Newsome and Harvey).
2.3.2.3.
To use these numbers, download Geotrans, and then in Geotrans create a
new datum with a Clarke 1866 ellipsoid (CC). Enter the dx, dy, dz, and make the
valid domain a few degrees either side of 77 W, 18 N. Click OK. In the lower
window, set the datum to the one you have just created, then set the projection
to Lambert Conformal Conic. Enter 77 W for the meridian, 18 N for the origin
latitude, and 18 N for both standard parallels. Make the False Easting 250000
and the False Northing 150000. Enter your GPS lat/long positions into the upper
window, with the datum at WGS84 (WGE), and then convert upper to lower. The
Easting and Northing displayed in the lower window are the Jamaica Metre Grid
coordinates used on the 1:50k topo maps. You can of course run the conversion
in reverse to turn JMG coords into WGS84 L/L.
2.3.3.
The parameters for JAD2001 follow:
Lambert Conformal Conic Projection
Datum: WGS84
False Easting: 750000m
False Northing 650000m
Latitude of 1st Parallel: 18 N
Latitude of 2nd Parallel: 18 N
Longitude of Central Meridian: 77 W
Latitude of origin of projection: 18 N
Spheroid Name: WGS84
2.3.3.1.
It should be first noted that the spheroid is WGS84. This means that
JAD 2001 is a datum in name only; it is in fact the reference spheroid against
which datums are offset. There is one great advantage to this and one
significant disadvantage.
The advantage, of
course, is that there is no need for a datum transformation to convert Jamaica
Grid Coordinates to WGS84, and visa versa; one merely deals with the
projection, the False Easting, and the False Northing. A 2D position will have
the same latitude and longitude in both JAD 2001 and WGS84, thus ensuring that
errors are not introduced by dodgy datum parameters when GPS derived positions
are turned into Ja grid coordinates.
The disadvantage
is caused by the geoid height. To put it simply, WGS84 sea level is not the
actual level of the sea in Jamaica. Because of variations in the Earth's mass
concentrations and resultant equipotential surface, the planet's true sea
level, the orthometric height, is not a perfect spheroid, but instead bulges in
some places and is dimpled in others. The WGS84 spheroid is just the best fit,
not a perfect model of the Earth's surface. To compensate for this, we have a
dataset that is not a model but is empirically derived. The name for this is
the WGS84 EGM96 geoid. It will tell you the actual, local altitude for a particular
WGS84 position. We can therefore see that this geoid height problem is not such
a great disadvantage and is easily overcome. An online Geoid Calculator can be
found at NIMA (note: orthometric Height = GPS ellipsoidal height - geoid
height).
We present below
a walk-through of how to convert WGS84 L/L to JAD2001 using Geotrans.
2.3.3.2.
Open Geotrans, and leave both the upper and lower windows at the
default datum, "WGE"; this is WGS84. In the lower window, click where
it says, "Universal Transverse Mercator (UTM)", and by using the drop
down menu on the right, set it instead at "Lambert Conformal Conic".
You will then see a new choice of variables and these must be entered as:
Central Meridian: 77 0 0.0 W, Origin Latitude: 18 0 0.0 N, 1st Std Parallel: 18
0 0.0 N, 2nd Std Parallel: 18 0 0.0 N, False Easting (m): 750000, False
Northing (m): 650000. You are now ready to convert positions.
In the upper
window, enter your Geodetic Lat/Lon positions and click, "Convert: Upper
-> Lower". In the lower window, the result is where it says
"Easting/X (m)" and "Northing/Y (m)". These are the JAD2001
Metre Grid Coords. You can reverse the procedure by entering the JMG in the
lower window and converting Lower -> Upper.
2.3.4.
To convert from JAD69 to JAD2001, and back, you will need to create the
JAD69 datum in Geotrans and use the methods described above.
2.4.
Species Identification
2.4.1.
We have received assistance in identifying invertebrates found in caves
primarily from Dr Stewart Peck, of Carleton University, and Dr. Christoph
Schubart of the University of Regensberg. As much as possible, we attempted to
do this photographically, but some collection did take place. Collected
specimens were stored in 70% ethyl alcohol for those that would be determined
through body morphology, and 95% ethyl alcohol for those that would be
identified by DNA sequencing. DNA sequencing was limited to stygobitic crabs
and shrimp, and continues to be carried out by Dr Schubart.
Project funding
did not allow us to pay experts to identify species, so we have relied on the
goodwill, and free help, of Dr Peck and Dr Schubart. Accordingly, things are
not progressing as quickly as we would like and many of the specimens collected
remain unidentified at this time. This backlog will eventually be taken care of
and we will issue a supplement to this report, to be delivered electronically
to TNC-J, when identification is complete.
2.4.2.
Identification of particular species in the past has allowed the author
of this report to determine their presence when encountered in caves. Amongst
these are Gaucelmus cavernicola, Troglopedetes jamaicensis, Sesarma
verleyi, Sesarma windsor, Nelipophygus sp, Neodytomyia
farri, and water striders in the family Veliidae. As time passes, and we
have more species identified by our collaborators, the list grows longer. It is
our intention to eventually publish a field key to Jamaican cave-adapted
invertebrates, and the JCO will forward a digital copy of this to TNC-J when it
reaches full fruition.
2.5.
Determination of Hydrological Activity
2.5.1.
In our assessment, hydrology is addressed in some detail. The
introduction to Appendix A will describe the data values used, but we will
discuss here the methods used for determining activity.
2.5.2.
The caves of the Cockpit Country may be broadly grouped into two sets.
These are: those that consist of stream passages that are active at least
during rainy times, and those that never see an actual flow, but in some cases
do have an input of water through percolation from the land above. We have
called these two sets Wet and Dry.
Stream passage
caves that have an actual flow of water during rainy times can be quite dry at
other times. To differentiate between these caves, and those that consist of
fossil stream passages that are always dry, we looked to the terrain
immediately outside of the entrances. In most cases, seasonally active stream
caves will have some sort of streambed at the entrance. It might be dry at the
time of the visit, but it will clearly show if there is at least occasional
activity. The topography will also indicate if the entrance is a sink (i.e.
taking water from the outside), or a rising (i.e. a resurgence). If the
streambed found at the entrance runs across land that drops in elevation as one
moves away from the cave, it cannot feed water into the cave. This might seem
obvious, but if one looks only at the entrance, not the surrounding terrain, it
will be uncertain which way the water is flowing in the rains unless the slope
is pronounced. We used two methods to be sure of direction of flow: actual
examination of the terrain while in the field, and examination of the
topographical maps afterwards, when the positions obtained with the GPS were
plotted.
2.5.3.
Determination of hydrological activity inside the cave, in passages,
was done by looking for stranded detritus on walls and ceilings. When a cave
takes water, inevitably some material is washed in. In the past, this would
consist entirely of organic material, but in many cases now the detritus also
consists of trash and litter. Along with bamboo leaves stuck to the walls,
there will be plastic bags, etc (in one case in St James, we have observed a
large tire hanging on a stalagmite). The organic debris is very good for
showing the time elapsed since the last flooding of the passage, because the
older it is, the more rotten it is. One cannot say how many months it has been,
but one knows if it has been months, or years. Examining how far this detritus
extends vertically in the cave directly shows how high the water rose during
the last flood period. In some cases, the debris will be hanging on formations
on the ceiling, indicating that the passage flooded to the roof. In caves where
this occurs, the invertebrate species present will be different from those
caves that always retain some dry space.
2.5.4.
Caves that are risings can still have organic debris, trash and litter
in them. This will occur when there is an upstream sink into the cave that
feeds detritus to the system. That sink may be another "entrance" to
the cave, and allow human entry, or it may be impassable because of siltation
or boulder-chokes, and is thusly not considered an entrance. We have determined
the locations of choked sinks for several caves that are risings (e.g. Swanga),
and included this information in both the notes and the database.
2.6.
Field Techniques
2.6.1.
We will quote extensively from information available on the JCO website
in this section. We present first a description of our field techniques, and
our recommendations for an overall approach (2.6.2), and then general guidance
for cavers and researchers who might not be familiar with conditions in the
field in Jamaica (2.6.3).
2.6.2.
Our approach to cave exploration and monitoring on the island of
Jamaica differs from the traditional methods employed in the initial surveys
and route finding of the past. Although the work accomplished by the GSD, NSS,
JCC, Bristol U. et al. [1] was truly invaluable and provided the base upon
which subsequent exploration and monitoring could proceed, the advantages
gained by the use of large parties when balanced against the potential for harm
to the cave environment suggested that a different approach was needed.
The progression
of Mountaineering methods, from the early years of Mallory, through the “siege
tactics” employed for the first ascents of Annapurna, K2, Kangchejunga, and
Everest and on to the, “fast and light”, approach favoured during the seventies
and eighties, can serve as a useful analogy for caving techniques. It was found
that although the use of large parties, great quantities of gear, food, and
logistical calculations could indeed put someone at the summit, the increased
risk and costs, both human and monetary, made the structure created fragile and
expensive. Improvements in Single Rope Techniques eventually enabled small
teams to be more certain of achieving the sought after result, and “siege
tactics”, became something only currently employed in the tourist industry. As
in mountaineering, improvement in rope and gear has created new opportunities
and enabled a small team to safely and thoroughly monitor and explore
unfamiliar or new caves in a short time with minimal harm to the environment by
using only SRT and temporary protection. We will outline below the methods used
and the advantages gained.
2.6.2.1.
Size of Team
The optimal
number of cavers engaged in any one cave is three. Two is insufficient for any
self-rescue attempt; it requires two team members to transport an injured caver
out of a cave. The use of a fourth member will slow the progress on difficult
ground, especially when talus slopes and rockfall are factors. Communications
will be less efficient; the larger the team, the more chance there is for
confusion. Interaction with the cave ecosystem and the possibility of damage to
formations requires the use of the smallest possible team. As seen above that number
is three. That said, the JCO often uses four people, but broken into two teams
of two people each who know the location of the others and can provide mutual
assistance. To make this work, there must be definite rendezvous times arranged
beforehand
2.6.2.2.
Rope
With modern nylon
rope, there is no need for cable ladders. However, the frequent presence of
sharp rock in Jamaican caves, when combined with the use of SRT, makes the use
of 11mm static nylon rope the best choice rather than the lighter lines often
used by mountaineers. If all ropes and webbing are inspected regularly for wear
and damage, then the use of cable ladders does not need to be considered. The
great weight involved is unnecessary with a team of three and proper SRT, and
there will be less damage done to the cave because of the use of a smaller
group. Large teams are only necessary when ladders are used.
2.6.2.3.
Anchors and Protection
All anchors must
be temporary. SRT when used with tubular webbing slings on natural anchors
eliminates the need for bolting on all movement downward into a cave system.
This is the scenario encountered most frequently in Jamaica. In most caves,
there will be natural protection in the form of boulders or large stalagmites
available at some distance. Tubular nylon webbing with a width of 25mm is very
light, very strong, has little tendency to roll on rock and does minimal damage
to formation structure. Slings should be placed around the anchors, then
caribinered to the static rope. The length of the sling must be such that the
carabiner and the sling lines will form an angle of no greater than 90 degrees;
i.e., slings should always be of a circumference at least 50% greater then that
of the anchor. The angle formed by the static rope and two anchors should not
be greater than 90 degrees. [2]. Long single lengths can be extended to the
edge of the drop, if necessary. Long lengths of webbing should be brought along
on every expedition so that two anchors may be found up to a distance of 50m
from the pitch. It should be noted that webbing by nature of its flat profile
is less liable to be cut by rolling on a sharp edge at the lip of the drop.
Rope protection in the form of a pad or slit hose should be strongly considered
if it is necessary to have the static rope in contact with sharp edges. All
caribiners should be of the locking type. Deviations or re-belays should use
only natural anchors slung with webbing. If initial upward movement cannot be
achieved through belayed climbing using slung chockstones, non-fragile
formations or rocks, or by the use of lightweight maypoles, the route should be
abandoned; preservation of the cave structure must be given priority.
2.6.2.4.
Descent and Ascent
Descents on
anything other than very long drops are most easily accomplished with the use
of a Figure-8. The weight saved when compared to Racks is considerable; the
simple nature of their use makes them much less prone to being set improperly
when compared to more complicated mechanical descent devices. On pitches
greater than 30m, Racks are to be preferred due to their greater ability to
absorb and radiate heat built up through friction. The use of a safety brake in
the form of a Prusik knot is not recommended due to the doubtful outcome in the
case of an out of control rappeller. The wisest course is to ensure that the
other team members are not in a position to cause rockfall onto the rappeller.
This careful positioning of team members at both the top and bottom of pitches,
when strictly adhered, to will eliminate the chance of an experienced caver losing
control on a descent. The only real danger encountered is rockfall and if the
person on rappel is not hit, then there is no need for a belay or anything
other than SRT.
Ascenders of a
quality comparable to Jumars, when used correctly, negate the need for a third
“safety” ascender. Use of the European, “frog”, system [3], with the upper
Jumar backed up with a tie-in to the seat harness is not only safe but
eliminates the extra weight of a third ascender or problems associated with
Prusik knots as a backup. An easily tied length of webbing can be substituted
for the chest harness to keep the chest Jumar in place. This system is more
energy efficient than rope-walking methods on long pitches and permits the
passing of diversions, re-belays and knots more easily. If all tying in, and
setting up of gear is checked thoroughly before the ascent, there is no need
for belaying. The two other team members will be out of the rockfall zone, or
if at the top of the pitch, in a position where nothing can be dropped onto the
ascending climber. Etriers of suitable length can be useful at the top of a
pitch, especially in the case of overhangs. Climbers should stay attached by
the Jumars to the rope until a completely safe stance is reached.
2.6.2.5.
Movement on Talus Slopes
Steep talus
slopes such as the second entrance at Bristol Cave and the top entrance at
Windsor Great Cave require special precautions. There is a real danger of
starting a serious rockslide; movement must be cautious and staged. The use of
long static ropes and gear on this type of ground often makes the situation
worse. The rope will tend, in its natural to and fro motion, to dislodge rocks
directly above the caver who is on-rope. Progress is best accomplished through
delicate movement by the caver and an awareness of the danger. Only one caver
should move at a time; the other two cavers should be stationary. Look for the
most probable route of falling rocks and then find a good stance as safely out
of the way as possible. The caver in motion must take all care to avoid
dislodging rocks but it should be noted that there is a likelihood that rocks
will indeed fall.
2.6.2.6.
Light and Batteries
All lights should
be electric. The effect of combustion by-products on cave fauna is
undetermined; carbide should be avoided. The three members of the team should
each carry two primary sources of light and one backup. The two primary sources
should consist of a headlamp mounted on the safety helmet and a hand lamp for
conditions when insect numbers preclude the use of the headlamp. The backup
light can be as small as a Mini-Mag but should have fresh alkaline batteries
and should never be used unless necessary. It is helpful if one of the team has
a powerful 6V tight-beam hand-lamp for finding openings in large chambers. The
hand-lamps should be attached with small diameter Kevlar line or webbing to the
harness to prevent loss on difficult ground. Each caver should use only one
light at a time, when possible, and turn off all lights during rest stops. Each
caver should carry one set of extra batteries and spare bulbs for every light.
If rechargeable batteries are used, they must be at least Ni-Cad and the
duration of the battery life must be determined. It is advisable for every
caver to have one of the extra sets be fresh alkaline batteries. It should be
remembered that the shelf life of batteries in Jamaica is usually short due to
the ambient heat during storage.
2.6.2.7.
Route Marking
Route marking
should be of a temporary nature. It is best achieved by the use of flagging
ribbon removed after use. The cave system should be left as it was found. All
junctions should have the initial entry passage marked in a manner that
indicates the ultimate way out. This can be done by using different colours of
ribbon or doubling the ribbon in the direction towards the entrance. On
unfamiliar ground flags should be visible from adjacent flags. The use of
Scotchlite reflective cloth ribbon is to be considered despite the cost; it can
be reused many times and is easily visible in low light conditions. An accurate
compass should be brought into the cave system and consulted often by the lead
caver to maintain orientation. Altimeters can be useful in many situations
although their accuracy is problematic in conditions of high humidity or
rapidly changing barometric pressure. Physical surveys are best carried out
with a non-intrusive method such as laser range finding to avoid widespread
interaction with the cave floor. Compaction destroys the habitat for many floor
dwelling invertebrates.
2.6.2.8.
Self-Rescue and Safety
It is unwise to
assume that outside help will be available in the case of injury or confusion
over the route, in any Jamaican cave. You must be prepared to get yourselves
out. That being said, in cave systems with multiple pitches it is advisable to
have, when possible, a strong, responsible member of the local community at the
top of the first drop. Injuries are least likely to occur when the movement is
vertical on rope; more likely is a bad fall on slippery or rocky ground. If
problems arise, it will probably be in the form of bad cuts, abrasions and
broken limbs. A basic first-aid kit is advisable. Include compression bandages
and lightweight splints. If faced with serious injuries, yam-sticks, bamboo
etc., are often near to entrances and, when used with webbing and harness, can
be used as a very functional stretcher. Bring two carabiner slung pulleys and
adequate rope for mechanical advantage up pitches. Wear a helmet and strong
boots. Take as few chances as possible. Never, ever get lost. Always consider
the worst-case scenario and how you would respond to it. Remember at all times
that caving is inherently dangerous.
2.6.2.9.
Cave Etiquette
Never has the old
adage, “Tread lightly upon the land”, been more appropriate than in the case of
caves. Cave environments are fragile both biologically and structurally. Those
of us who are fortunate enough to gain access to these hidden places bear a
great responsibility; the preservation of that which attracts us. Formations
that have taken tens of thousands of years to grow can be destroyed by one
wrong move. Bat populations, especially during the time before the pups are
weaned, are highly susceptible to harm during even brief entries into caves.
Troglobytic crabs and other invertebrates can be crushed underfoot by a
careless caver. The overall health of the cave system must always have top
priority. First and foremost in the mind of any caver in Jamaica must be the
question, “Am I doing harm?” If the answer is, “Maybe”, then the expedition
must be reconsidered. Some of the caves that once supplied habitat for bats
retain substantial colonies. Some show historical evidence of bat occupation,
in the form of staining, and guano, but have been abandoned because of human
activity [4]. When passing through caves with existing bat populations it is
essential to keep light and noise to a minimum. Avoid shining lights toward the
roof of the chambers. Spend as little time as possible in roosting areas. Many
invertebrates make their homes in the loose guano found on the floors of
biologically active caves. Compaction is a danger to these creatures and is
best minimized by keeping to one track. Try to establish a route that all three
can stay on and use it for every passage through the cave. Formations should
never be wilfully broken or removed. Cavers must resist the temptation to leave
signs of their visit to a cave system [5]. Collection devices and bottles used
for research purposes must be removed as soon as their purpose has been served
[6]. Researchers should avoid leaving permanent markings [7]. Any available
opportunity should be taken advantage of to educate local Jamaicans in the
factors influencing the health of their cave. This is best done over cold Red
Stripes, at the closest shop, in a friendly and respectful manner.
2.6.2.10.
The advantages gained by employing a small party of cavers using SRT to
explore and monitor caves are two-fold: The expedition is fast, light, flexible
and requires a much smaller outlay of monetary and human capital. The damage
done to the cave environment is minimized by the avoidance of cable ladders,
the small number of cavers on the team and by spending the least amount of time
interfering with the cave ecosystem. Fewer lights are required, noise is
reduced, less compaction of guano is caused and there is a lessened chance of
invertebrates being walked on. The Single Rope Techniques required are
trustworthy and proven. Thorough familiarity with SRT methods is necessary
before entry into a cave, but the skills are easily learned and used. The use
of large survey parties in the future should be reconsidered, despite the great
work accomplished in the past.

2.6.3.
The following section is generally intended for first-time visitors to
Jamaica, and we present it here for those who might read this report in Foreign
and contemplate a trip to the island to explore its caves.
2.6.3.1.
Logistics (getting where you're going with what you need).
Transportation
will usually present difficulties for visiting cavers. The three options are:
to rent, to hire a driver, or to buy a car.
The first choice,
to rent, while seeming chancy to a person handing over a credit card, is a
viable option. Most of the car rental companies are as trustworthy as those
found anywhere else on the planet. The increased mobility, and lack of the time
constraints imposed by having a driver waiting, will make it possible to do a lot
more caving. Be sure to get a car with good clearance. Despite the extra cost,
a 4 x 4 can be very worthwhile and will always get you where you want to go.
Smaller vehicles such as Starletts and Corollas can also be suitable depending
on the districts that you intend to visit.
However, if
you're nervous about driving on the left, concerned about putting down the
deposit on the credit card, or intimidated by the madmen taxi-drivers who
careen around the roads of Jamaica, then consider hiring a driver. This will
require careful, lengthy, negotiations with at least several drivers. You will
have no problem finding a number of candidates from which to choose. Firstly,
try to determine which one is least likely to rush you for more $$ when you are
in the field. Make sure that he understands that he might be getting back late.
Make sure he has a vehicle with suitable clearance for the rough roads you will
encounter. Compare prices and try to get the best deal from the most honest
person. Do not head off into the hills with someone who seems dodgy.
The third option,
if you expect to visit Jamaica often or already live there, is to buy a car.
Lada Station Wagons can be purchased for a reasonable cost, have good clearance
and traction, and parts are cheap and available. It ends up being much cheaper
in the end, if you intend to do a lot of caving. Make sure you shop around;
don't be timid about haggling.
Whatever way you
travel, expect rough roads, wandering livestock, large cane trucks suddenly
coming around corners, and flat tires. Try to not let it get to you.
When heading into
the hills to cave, always go prepared. In addition to ropes, vertigear,
batteries, bulbs, helmet, headlamp, maps, flagging and all the other equipment
necessary for entering a cave, you'll need food, water, and money.
It will not
always be possible to find food and water in the vicinity of the caves.
Although small shops are common in rural areas of the island, some caves will
be so remote that you will be either eating what you have brought or you will
be going hungry.
Water can be an
even greater problem. Be sure to bring as much as you can carry, and expect to
go through over 2 litres per person per day. The climate of Jamaica is hot,
even on a cool day, and those unaccustomed to these temperatures will sweat
profusely both in and out of the caves. Tales are told of tourists who have
almost died of dehydration after having ventured on long hikes into the hills
without an adequate supply of water. If you seem to have extra near the end of the
day, and your back is feeling the effects of having carried too many kilos,
then you can always pour it out to lighten the load, but never do this until
you know for certain that what remains will be enough to last for the hike out.
Bring money.
Bring real money, not plastic, in Jamaican dollars. Wean yourself from
dependence on bank or credit cards. Forget everything everyone has told you
about using U.S. dollars, and bring an adequate supply of Jamaican cash in
denominations smaller than the 1,000$ bills, commonly know as Joshua's, that
the cambios will try to give you. They are almost unspendable because no one in
the hills will ever be able to make change for such a large bill. The best
bills to bring are 100$. Bring a good supply, you won't be mugged or robbed of
them. Be brave; carry cash.
If you have done
things properly, you will now be in the hills, in the right parish and
district, and ready to look for a cave.
2.6.3.2.
Site Location (finding the entrance).
There are a
number of "Show-caves" on the Island, and although these consist
mostly of grottos located near resorts along the coast, some large inland caves
may be easily located and will usually have someone close-by that will act as a
guide and give you a "tour". If you have no, or limited, experience with
caving, it is suggested that you start with one of these tours. For those who
have had at least some experience in the underground, and who will be seeking
rarely visited systems that seldom see tourists, the actual finding of the cave
entrance can be very difficult.
Cavers interested
in serious caving in Jamaica are encouraged to make two purchases: Firstly, a
copy of Alan Fincham's book, Jamaica Underground. It gives a good overview, and
will help greatly in deciding on what caves to pursue and how to find the
general area where the caves are found. Nevertheless, many of the sites listed
in the book are unknown, or seldom visited, by the people of the district and
the positions given are accurate to 100 metres nominally, and in practice are
at times out by hundreds of metres. The entrances to many large cave systems
are sometimes quite small and/or hidden in the bush; it is possible to stand 20
metres from the entrances to many caves and yet see no trace of the way in.
This leads us to the second purchase: Topo maps of the 1:50,000 Metric Grid
Series for the areas where one will be. These, despite the datum shift problems
that render the stated latitudes and longitudes virtually worthless, are
invaluable. The metric grid found on these maps is the coordinate system used
in the Jamaican Cave Register. More importantly, by using the topos and
standard orienteering techniques it is possible to logically deduce where a
given cave may be found, and then by use of map and compass, find it.
Hydrologically
active systems will always be associated with identifiable features on the
topo, either as a source of a river, or a sink that take the waters of one.
Often the streambeds will be dry outside of the rainy season, but the feature
will be shown on the map and can be found on the ground as an obvious dry
river-course.
Caves that
consist of simple breakdown chambers usually have the entrances located on the
sides of hills, or on saddles, and are seldom found low in a cockpit.
Sinkholes are
located in cockpit bottoms, or obvious blind valleys. In fact, if the blind
valley has a large enough catchment (i.e. the area funnelling the waters to the
low point), then more often than not there will be some sort of sinkhole. These
will often be choked or narrow fissures, but it is possible to look at the topo
map and predict the presence of such a feature.
When one has
completed the homework, it is time to get out in the field to find the cave.
The first thing to try, always, is finding an older gentleman who has farmed,
or cut lumber, in the area where the cave is thought to be. It is often
possible to trade a few cigarettes, or a couple of beers, for valuable
information. It can be made clear that you don't actually require any work from
the person, just information about openings to caves that the person may have
come across over the years. Stress that you are searching for, "a serious,
dread cave, man, not just a likkle shelter", or else you may wind up
hunting down countless shelter caves and waste the limited time that you'll
probably have. Unless the cave has been mined for guano, the local people will
have not entered it because of lack of flashlights and will be mostly familiar
with shelter caves.
If no one can be
found who knows of the sought after cave, then it's time to guess at the most
likely place and start beating the bush. Always bring along a machete or two.
They will be required if one is to stand any chance of finding a site that has
no trail leading to it. Search methodically. Use the compass and try to approach
it by running a grid. Either east-west or north-south, methodically sweep line
after line through the bush. With much work, this will often find you the
entrance. Be aware that most of the time you will not be on level ground, but
will be working rocky, vined-up hillsides or bamboo-choked bottom lands.
Sometimes it will
take more than one attempt to finally succeed. Sometimes you will never find
the thing. Never expect 100% success because it will never happen.
Having now found
the cave (think positively), you can put on the helmet, switch on the lights,
and head on in. This brings us to the physical challenges to be expected once
you have entered the caves of Jamaica.
2.6.3.3.
In the Cave (what to expect and how to not die).
Jamaican caves
are formed by the percolation, or flow, of the slightly acidic rainfall that
twice a year pummels the soluble limestone in which the systems are found. The
resultant terrain is called Karst topography. In the central part of the
Cockpit Country, all rivers flow underground. In other areas, rivers will
appear and disappear along their course as they take the easiest route to the
sea. This is what makes the island such a wonderful place for cavers.
Because of the
great amount of precipitation received during the two rainy seasons, May-June,
and September-November, the caves of Jamaica grow much more quickly than those
found in more northern parts of the world. Formations can be spectacular as a
result, but this bounty of water introduces two important elements to caving on
the island: mud, and flood-risk. The mud, if you are good on your feet, is
merely an annoyance. The flood-risk is real and dangerous.
In many caves,
the mud will make walking and scrambling treacherous. It is a rare person who
does not occasionally find themselves doing a little dance of slipping and
sliding as they try to stay upright. Always wear a helmet for this reason if no
other. If you take a fall, it might be on to boulders far down a nasty slope,
or on to sharp rocks right under your feet. You do not want to bounce your head
off any of these. This mud also makes photography difficult without having fine
grains of material lodged in all moving parts of the camera forever. If you
bring a camera, work out a way of keeping it clean. It has been found that
keeping it in a ziplock bag and only exposing the lens when shots are taken,
while holding the camera with your hands on the outside of the bag, can work.
There are probably other methods but give this some consideration before you go
in.
The risk of rapid
flooding in hydrologically active caves, during the rainy season, is real,
dangerous, and must never be forgotten. We have seen water levels rise at a
rate that would not be believed unless you had witnessed it yourself. This rise
can be on the order of metres per hour. If you repeatedly take chances at the
wrong time of year in such systems, you will eventually die in a cave. It
cannot be over-stressed that you must not enter a river cave that has long
stretches of low passages or crawls during the rainy season. If you do, there
is a very good chance that you will end your days in a watery grave; there will
be little chance of your body ever being recovered.
Assuming that you
have taken precautions to avoid drowning or knocking yourself unconscious in a
fall, there are still further considerations: Self-rescue, not getting lost,
and etiquette.
Be aware that if
you run into trouble, by getting lost or having a serious injury, no one will
come to rescue you. When you are in a serious cave in Jamaica, in most cases you
are on your own. No one will come to help because no one will be able to. The
people of the district will not have adequate lights, gear, or expertise. They
will also not be too inclined to enter a dark hole where people who supposedly
know what they are doing have already come to mishap. Calls might be made to
the police, once it has been noticed that you have disappeared (assuming that
you've notified someone of your plans before you go into the cave), but when
they arrive, if they have found the cave entrance, they too will have neither
the gear nor expertise to do anything. They will call the army who will
probably take one look at what you have done and write you off as goners.
You must have a
minimum number of three people in the caving party so that two can assist a
third injured member out of the cave. Two people alone is not good enough. The
one will stand no chance of getting the other out. Do your best to avoid
problems and remember: you are on your own. This is part of the attraction for
some; it is refreshing to have your fate entirely in your own hands, but if
caving without a vast support system on the outside to come to your rescue is
not your cup of tea, forget about Jamaica.
Do not get lost.
If you do, you are on your own for all of the same reasons stated above. The
easiest method to keep from getting lost is to flag. Take rolls of flagging
tape, a different colour for each person, and use it. Flag more than you think
is necessary. No matter how well you try to remember the route that you have
taken in, it will all look different on the way out. In complex caves, every
flag must be visible from the adjacent flag. Come up with a system to indicate
line of travel outward when T-junctions are encountered so that you avoid going
in circles if you loop around to your previously marked route. Keep looking
back in complex systems of small passages. You might pass a spot where a
passage joins from above, not notice it, and because of inadequate flagging
take the wrong passage on your return. One's natural inclination is to go up,
and the upper passage will be followed by mistake. No flags will be found and
confusion will ensue. Do your best to ensure that the route out is never lost.
You might get lucky and recover it or you might not.
Etiquette demands
that we leave the cave as we found it. This means that every effort must be
made to recover the flags on the way out. Caves that you intend to visit again
in the near future may be left flagged in difficult or confusing sections, but
eventually every flag must go. Etiquette also requires us to take every
precaution to avoid damaging formations or stirring up bats unnecessarily by
shining lights on the ceilings of chambers where they roost. The cavers should
also attempt to stay to one path, rather than spreading out. Compaction of
material underfoot, especially in outer sections of caves where there will be
more biological activity, is damaging to the troglobytic species that live
there.
Remember at all
times that you are just a visitor to the cave and that many others call it
home. Caves in Jamaica are biological islands, with rich and diverse
communities of living creatures dwelling in the dark. Take time to look closely
and carefully at these. Consider how you might do less damage to their habitat.
Show some respect.
We now move on to
cultural considerations involved in Jamaican caving.
2.6.3.4.
Cultural Considerations (giving respect and getting respect).
If you live in
Jamaica, you can skip the next part. If not, please continue.
Although many
people visit Jamaica and never see anything other than a resort, for you things
will be different. You will get to see the real Jamaica, the one that the
resort bunch will never experience. This is a good thing.
If possible, do
not stay on the coast; find a good base in the hills. This has two advantages:
First, you will be closer to the caves. Secondly, you will be away from the
riff-raff that congregates outside the hotels waiting to rush any tourists who
are bold enough to venture outside of the compound.
The people who
live in the hills of Jamaica are much like rural inhabitants anywhere. They
live close to the land and know its ways and rhythms. The pace of life is less
frenetic. They say Good Morning and wave if they know you when you pass them.
They know the names of the birds, trees, and flowers that surround them. All in
all, they are great folks to spend time with. In the evenings, after a day of
caving, don't be shy, get out and meet them. You will not be robbed or chopped
despite what the hoteliers, in hopes of keeping you a money-spending captive,
might tell you.
Visitors who are
on the island for the first time, those who come from tightly controlled
"proper" countries, are sometimes taken aback by the boisterousness
and joie de vivre of the Jamaicans they meet. The one sure-fire cure for this
is to drop some of your reservedness and let them teach you how they have a
good time. This is best done over Red Stripe, with music and dancing, and as
long as you drink enough water before you go to sleep to avoid a hangover will
be very rewarding.
Special
conditions apply during the day when you are out caving. Do not expect
something for nothing. If you ask for information be prepared to offer
something in return. This need not be a great amount: cigarettes, a beer or soft
drink, a hundred Jamaican dollars, any of these will usually be enough payment.
If someone tries to rush you for 20 US$, walk away and ask someone else. An
older gentleman will often be your best source for important information but
youths can sometimes be knowledgeable and trustworthy.
Be conscious of
the fact that at times you will be on private property. Try to get permission
to cross people's land or yards when getting to a cave. If they ask for
something in return, negotiate but be fair. It will be rare that this will
hinder your trek to the cave, but have respect for other people's property in
the pursuit of your goal and always ask first, if possible.
Most of the
foregoing has involved your need for respect for the people you meet while
caving. As it goes most places, in Jamaica, if you show respect, you will get
it in return. You will be pleasantly surprised at how quickly local people will
come to appreciate what you do when they see you sliding down a rope into a
dread cave that most of them, like people everywhere, would never consider
entering. You might at times have an audience. Make it absolutely clear that
rigging and ropes must not be touched, and that no objects should be tossed
into the cave. You can consider hiring someone for a small amount to safeguard
things up top for you. This is an especially good idea when removal of a rope
from outside will cause you to be trapped. Ropes are very inviting to people
who have livestock that needs to be tied up.
Before closing
this section, it is important to remind you that even though you might be
comparatively poor at home, you will still have much more than many in the
hills that you will meet. Don't give away all of your money in a fit of guilt,
or let yourself be constantly rushed like fool, but at the same time don't be
afraid to buy someone a beer or shot of rum occasionally, especially if they're
a friend and you're downing your fifth Red Stripe as they get thirstier and
thirstier watching you.

Conclusions
4.1.
Current Conditions
4.1.1.
In 2005, the conditions found in the caves of the Cockpit Country span
a range that extends from highly-degraded to pristine. The criteria for the two
extremes of this range, highly-degraded and pristine, are as follows.
4.1.2.
Those caves that we regard as highly-degraded are in one or more of the
following states:
4.1.2.1.
They have lost historically recorded bat-roosts, for whatever reason,
or currently have bat populations that are orders of magnitude less than they
once were. (Example: Welsch Ratbat Cave).
4.1.2.2.
Bat-roosts have had guano deposits entirely removed. (Example: Vauxhall
Cave).
4.1.2.3.
Invasive species, principally the American Roach (Periplaneta
americana), have caused a great reduction in the variety of species that
would have been expected to occur in the cave if the roaches were not present.
(Example: Penthouse Cave).
4.1.2.4.
Siltation has greatly reduced the accessible area of the cave with
respect to what is known by historical records (i.e. determined by comparison
to past cave-surveys). (Example: Farmyard Cave).
4.1.2.5.
Human activity has caused appreciable damage to speleothems, introduced
large amounts of garbage, or altered the morphology of the cave in a way that
has caused a great change in internal-ambient conditions. (Example: Wondrous
Cave)
4.1.3.
Those caves that we regard as pristine are in the following state:
4.1.3.1.
They have rarely been entered by humans.
4.1.3.2.
The land-use outside of the cave has not been altered from its original
state to an extent that would greatly affect the interior of the cave. (Of
course, no part of the island currently has flora and fauna identical to what
existed before European occupation, but some caves have always had some amount
of forest around them, and many of the original native species continue to
exist in the local area).
4.1.3.3.
There has been no siltation, and no rafted garbage introduced to the
cave.
4.1.3.4.
There are no invasive species in the cave, such as P. americana.
(This automatically follows from a lack of visitation and absence of garbage.
Roaches to do not walk through the bush to get to a cave, they are carried
there, either in fertilizer bags or on rafted garbage).
4.1.3.5.
Unfortunately, there are only two that we can call pristine out of the
87 sites we have visited in the Cockpit Country. These are Home Away Cave, and
Barbecue Bottom Hole-2. Every other cave visited has been disturbed to one
degree or another. The reasons why the two pristine caves continue to be that
way are given below:
Home Away is not easy to
access. It is in forestland south of the Escarpment, and Pantrepant, and it is
a difficult hike. The logging appears to have always been selective, and there
is good canopy. A vertical pitch is involved to get beyond the entrance area.
There is no record of it having been explored prior to a JCO visit in 2001 (but
a large shelter chamber at the Main entrance has certainly been used in the
past, at least by the Taino, because there are petroglyphs present).
Barbecue Bottom Hole-2 is
also not particularly easy to access, although much easier than Home Away. It
has a large shelter cave at the entrance that has undoubtedly been used often
over the years, but the actual "cave" is reached via a 15m pitch at
the edge of this. This descent, with vertical gear, had never happened prior to
the JCO visit in 2005 (and it would be best if it never happened again).
4.1.4.
We have not yet assigned a value to individual caves that represents
the degree of degradation, but this could be easily derived through filtering
of the database and is on our to-do list. We invite others to use the
information contained in the database to determine this for their own purposes.
We would appreciate suggestions on additional indicators that we might use in
the future.
4.2.
Degradation
Although we have not
assigned a definite value for the degree of degradation found in any particular
cave, we will discuss below the mechanisms involved and cite specific examples.
4.2.1.
Guano extraction:
During the Second World War,
Jamaica was in need of fertilizer. The guano deposits found in caves with
bat-roosts were an obvious source. The Lands Department (later to be renamed
the Geological Survey Department) undertook a search for suitable caves, [1].
This began the modern era of the exploitation of caves for bat guano resources.
We do not know to what extent guano extraction had taken place before then, but
it certainly put the idea in everyone's minds afterwards.
Guano mining from the time
of the GSD onwards has been carried out primarily by the commercial sector and
small-scale farmers. The number of sites that were mined by the government in
the early part of this era is a fraction of what was carried out by others
afterwards.
Large-scale commercial
mining in the last decade has been primarily for the export market, to supply
hydroponics gardening stores in North America and Europe. The JCO looked into
this two years ago and identified one of the main sources, and the primary
distributor, but we will not name names in this document, lest we invite a
lawsuit. We will say that tremendous damage has been done to some caves,
although we know of none currently being commercially mined in the Cockpit
Country. We have limited the positional information available on our website
for sites that are at risk, to avoid causing this to happen.
Local farmers are the second
of the groups currently mining guano. It is taken in relatively small amounts
and does not have the vacuuming effect of commercial operations. It is, though,
very widespread and frequent in caves that have not already been exhausted.
The damage that is done to
caves by guano extraction is addressed below:
4.2.1.1.
When detritus is not available, much of the fauna in Jamaican caves is
dependent on bat guano as the food source. The wholesale removal of the bat
guano eliminates the bats in the process through repeated disturbance of a
creature that lives on the metabolic edge. It also results in the elimination
of the species that depended on it. The cave biota is greatly altered. Bats
might eventually return, but perhaps not with all of the original species. The
troglobitic invertebrates may never return. Several examples of heavily mined
sites that had large bat populations according to historical records, but now
have none or few, are Vauxhall Cave, Carambie Cave, Welsch Ratbat Cave, and
Penthouse Cave.
4.2.1.2.
As well as supplying a habitat for living creatures, old guano deposits
contain records of the climatic conditions of the island that extend back for
thousands of years [2]. They also contain the fossilized remains of Quaternary
fauna. When the guano is shovelled into bags, and shipped overseas, all of that
is lost.
4.2.1.3.
Physical damage to formations is unavoidable during the mining process;
it is not possible to have people shuttling in and out of a cave repeatedly,
with fertilizer bags on their heads, and not have speleothems being hit.
4.2.1.4.
The main vector for the introduction of the invasive roach P.
americana is the fertilizer bags that are commonly used for removing guano.
Roaches crawl into the bags to consume the guano at the yard where the bags are
stored between use, and then hitch-hike into the cave the next trip.
We find a direct correlation
between guano extraction and the presence of invasive roaches. Filtered
extracts from the database illustrate this in Table 4.2.2.4, described below:
First, it will be seen that
of the 18 caves we identified to have definitely been mined (evidenced by
fertilizer bags, scoops, or by historical records), 12 have roaches, and only 6
do not. Secondly, of the 6 that do not, 5 of those were mined in the early part
of the era (our definition of Historic is more than several decades ago, and
our definition of Current is having occurred during the last few decades). It
appears that current activities are a factor in the presence of roaches. In the
Cockpit Country, all of the current guano extraction is being done by local
farmers. The one cave currently being used that does not have roaches is Nanny
Cave. This seems to be because the roost is limited to Artibeus fruit-bats in a
twilight area just inside the entrance (apparently, Artibeus will put up with
more light than American roaches). The rest of the cave is a low stream passage
that floods often.

4.2.2.
Periplaneta americana (American Roach):
The American Cockroach is an
introduced species that has become abundant in some caves. It is very good at
what it does, which is scavenging, and it has out-competed most other
invertebrate scavengers that it has come up against. The effect of this is
two-fold: the native scavenging species that were not able to get to the food
first starved to death (P. americana move very quickly); some of the
species that were out-competed, and eradicated by the roaches, served as food
for cave-adapted invert predators that then lost their prey. The result is that
caves that have had P. americana introduced have seen a great loss of
their original biodiversity.
The JCO has seen this effect
at its greatest in two caves outside of the PiP Project area. These are St
Clair Cave in St Catherine, and Geneva Mountain Cave in Westmoreland. Both
sites have large bat-roosts and few invertebrates other than roaches. There are
no caves affected to this degree in the Cockpit Country, but there is the
potential for this to happen at Marta Tick Cave.
4.2.2.1.
Marta Tick has a large bat-roost that is seldom disturbed due to its
inaccessibility (in the bush north of Quick Step). Guano deposits are thick and
fluffy. There are many troglobitic invertebrate species. There are no roaches.
Some guano extraction has occurred, but it has been infrequent and very small
amounts have been taken. To our knowledge (we are quite familiar with the
area), there has been no mining in the last 3 years, and possibly none for much
longer than that. If land-use changes, to bring farmers closer to the cave, it
is inevitable that roaches will invade. Marta Tick is an example of a cave in a
primarily natural state.
On the other end of the
spectrum is Welsch Ratbat Cave. It is located close to farmland and has been
mined often for guano. The deposits are exhausted and current mining activity
is low (2005). There were no bats seen during our visit. We consider it to be
highly-degraded.
4.2.2.2.
We will contrast Marta Tick Cave, in 2005, to Welsch Ratbat Cave.

Table 4.2.3.1
In addition to the species
listed for Marta Tick, we also saw Gaucelmus cavernicola; Nesticidae fam;
Troglopedetes jamaicanus; and Marava jamaicana. There were other
species seen that were not identified.
At Welsch Ratbat, no other
species were seen, other than the frog E. cundalli near entrance openings.
We believe that the greatest
factor in the difference in biota of the two caves is guano mining.
Secondarily, it is the presence of American Roaches. Troglobites are found in
nutrient poor caves (and in some cases prefer them) as long is there some
amount of food available. Although we did not see any bats, we did see
individual faeces that indicate an occasional use continues. The people of the
district, whom we asked, told us that at certain times of year there are bats
in the cave. The only invertebrate species that we saw were roaches. We suggest
this mechanism is at play: There is limited nutrient input, but there is some.
The roaches have been getting to it first, before other scavengers, since their
introduction to the cave. They have now eaten everything else out of house and
home.
4.2.2.3.
It is difficult to remove American Roaches from Jamaican caves. The
author of this report read of a study that was combating a similar invasive
roach, albeit not one in caves, by using pheromones. Perhaps it will someday be
possible to remove the roaches from the caves, but it will certainly not be
easy. What can be done now is to prevent them from invading the few bat-caves
that are not yet infested, and number one on the list must be Marta Tick Cave.
4.2.3.
Siltation:
Siltation is a process where
loose soil and clays are washed into river caves by seasonal rains. It is most
pronounced when the flow is across cultivated land into a cave entrance that
takes water (i.e. a sink). If great enough, the siltation can fill a cave with
mud to the extent that it can no longer be entered.
The main factors influencing
the rate of siltation are the slope of the catchment area and the degree of
ground cover. When a steep slope upstream of a cave has loose cultivated soil
(as found with many Yam farms), the resulting siltation will be severe. The
siltation is also severe on shallow slopes if the cultivated area upstream is
large enough.
Siltation is a great source
of cave degradation in the Cockpit Country. Many instances will be found in the
database and our notes for the caves. The local negative effects are a
disruption to traditional drainage patterns and the removal of habitat for
troglobitic and stygobitic species. On a larger scale, the river caves that are
affected by this problem are often an upstream part of the water supply for
downstream communities. When the waters that rise in Springvale are muddy, and
the Pumphouse must be turned off, it is because of topsoil that entered the
system at the farmlands of Maroon Town.
We present three cases here
that illustrate the process of silt input to caves, all in the southeast
Cockpit Country. The first two, Wilson's Run and Farmyard caves, are
highly-degraded. The third, Pool Cave, is an example of a cave with minimum
siltation due to good ground cover upstream.
4.2.3.1.
The following is from our notes for Wilson's Run Cave and is our first
example of a cave highly-degraded by siltation.
"The
topology of the cockpit that we reached, where the cave is listed to be, is
such: a medium-sized cockpit bottom is surrounded on most of it's circumference
by slopes of up to 45 deg. Where the slope extends furthest, to a generally
higher area to the south, much of the hill is in yam cultivation. Across the
bottom of this cockpit, a stream flows. It rises from the bottom of the hill on
the southeast and flows to the northwest, to sink, we believe, in Wilson's Run
Cave. I say "believe", because although we did trace the course of this
stream (with much effort), to where it sinks close to the other side of the
cockpit, all we found there was a cut in a low hill where the waters sank into
what appeared to be mud-choked boulders (the boulders were not visible, but
something was holding a great amount of mud in place at the stream sink). The
cut into the hill faced in the right direction for the entrance according to
the Liverpool cave map.
At
any rate, there was no entrance to be entered, just small holes in a large
section of inclined muddy pit into which the stream drained. It should be noted
that in many cases the Jamaica Underground positions are out by hundreds of
metres. When there is a map available for a cave, such as Wilson's Run, this is
how we make a positive identification, especially in districts where there are
many caves. In this case, it was not possible. The area map, and the text
description, certainly indicate that we had the right target, but we cannot put
the identification at 100%. But, assuming that we indeed were at Wilson's Run
Cave, the explanation for the lack of entry is obvious: the yams on the hills
above.
Inquiries
were made of residents of the area on how long the yam farming had been going
on. We were informed that it began about 10 years ago (apx 1995), and greatly
expanded in the last 2-3 years. A close look was taken at the cultivation
technique, and it was seen that the main drainage trenches led directly
downhill into the bottomland. The soil is deeply cultivated. A build-up of silt
was seen in the streambed that crosses the cockpit bottom. Wilson's Run Cave,
unfortunately, has likely joined Farmyard Cave, Rock Spring, on the list of
caves lost due to agriculturally induced siltation. Perhaps if the drainage
method employed on the hills above were to change, this stream cave might
eventually be flushed clear, but this is uncertain."
4.2.3.2.
The following is from our expedition notes for Farmyard Cave and our
second example of a cave highly-degraded by siltation.
"Before
me in the weeds was a very small opening about 75cm high rising from the dirt.
Calling out to Dietrich that I might have it, I took off my pack, turned on my
headlamp, and squeezed my head and shoulders in.
To
the left, a low passage ended in mud about 5m away. To the right, the passage
carried on past the entrance, also low and muddy, but continuing if you were to
slither on your belly. D had now caught up, so I slithered in to see what could
be found. After about 20m, I saw signs of another small mud-choked entrance,
and now realizing that things were beginning to match the KHE map (although
with one great difference), I worked my way back to where I'd come in,
searching for what should be a continuing passage leading upstream, that is to
the left of the entrance that I'd come in by. It had looked mud-choked, but it
needed a closer examination. I spent 5 minutes looking for any chance of
getting past the choke, and found nothing. I crawled back out of the
"cave" to have a closer look at the printed scan of the cave map.
The
map, [found earlier in this report in the entry for Farmyard], shows the
passage that leads upstream or at least once did, because it does no longer. It
also shows three entrances, of which only two remain. Lest any who read these
notes suspect that I had found the wrong cave, note that the two entrances that
we found match the map perfectly in location and aspect. It is immediately
upstream of Thicket Entrance, Printed Circuit Cave. There was nothing else in
the vicinity that could be found. We had the right cave, but unfortunately, it
is now so full of mud and silt that it is essentially filled-in. I am unsure
which of the three entrances I entered by, but suspect it is what remains of
the "South Entrance". At any rate, we could only find two entrances,
so the third apparently is filled-in.
I
will quote the KHE notes from Jamaica Underground: "The southern
continuation of Printed Circuit Cave where flux passage reaches the surface at
Thicket Entrance. A meandering passage continues to the Main Entrance beyond
which are two ducks over rimstone pools and a crawl to a sump. Right leads to a
sump. Left, a low wet passage for 25m to a T-junction, choked on the left and
sumped on the right."
As
can be seen, this passage was never terribly high to begin with, and because of
the heavy cultivation of the land upstream (the sumps noted by the KHE were
merely low parts of the passage, and are being fed by upstream sinks with
locations undetermined), and at the entrances (which take water seasonally), it
is now gone. We noted several other cave entrances during our days in Rock
Spring, most notably Good Hope One Cave - Sink, that suffered from the same
problem, no doubt exacerbated by Hurricane Ivan, but Farmyard Cave was the most
extreme example. The district is heavily farmed, especially in the south
catchment area, by very hard-working farmers who constantly keep the land
tilled with no vegetative cover other than their coffee plants and yams, that
is, with roughly 95% of the dirt loose and easily washed away in heavy rains.
In fact, a farmer who was of much help earlier in the week showed us a sink
that was currently blocked (barely seen, but he knew where it was from when it
had been open) that he noted needed to be cleared to allow water to drain from
his field. What is one to do? The farmers are hard working, and doing the best
they can to maximize what profit is available, but in the course of this
industrious cultivation they are doing great damage to the river-caves that are
found here. I will merely describe the situation for now, but in the notes for
Pool Cave, which was quite silt-free thanks to an acre or two of bush cover at
the sink entrance that was holding silt, I will make what recommendations I
can.
One
can speculate that if vegetative cover were to return to the catchment area,
eventually the mud in the cave might be washed out and the cave would return,
but realistically this has a low probability of happening at any time in the
near future. For now, there are no biological observations for us to note,
because there was virtually no cave for us to access. Perhaps upstream,
something remains, but it is not possible to get to it without many weeks with
a shovel, tunnelling up the passage."
4.2.3.3.
The following is from our expedition notes for Pool Cave and an example
of a cave that is not degraded by siltation.
"This
cave was visited immediately after Crayfish Cave. We entered through the rising
entrance, and exited from the sink entrance. We noticed soon after we were in
the passage that siltation was low. When we came out at the far end, we found
that the seasonal streambed that feeds into the cave had a very dense cover of
bush and shrubs, with the more open areas covered with tall weeds. This was the
only sink in the district that we found in this state, and it was the least
muddy cave. The floor of the passage was clean rock, and rimstone pools held
clear water. This cave can be contrasted well to Farmyard Cave that is not far
away. Farmyard, which takes most of its flow from cultivated land, is almost
entirely choked with silt.
The
passage held no rafted-in garbage. Invasive roaches were not present."
4.2.3.4.
The above examples are not isolated instances. Other sites will be
found described in the notes, and found in the database, that show the same
pattern; siltation is directly related to land-use with cultivation being the
main factor.
4.2.4.
Tourism:
We have
not found tourism to be a great factor in the degradation of the Cockpit
Country caves. Of the 87 sites that were investigated, only three were used for
tourism. These are Windsor Cave, Printed Circuit Cave, and Wondrous Cave.
Guidelines and monitoring are highly advisable, but at the current level of
activity, tourism is not an immediate threat to the biota of the Cockpit
Country caves.
4.3.
Conservation priorities:
The factors in the
degradation of the Cockpit Country caves have been discussed in the preceding
section. In this section, we will identify conservation priorities and sites
most deserving of protection.
4.3.1.
Priorities:
4.3.1.1.
Our investigations indicate that guano extraction is the greatest threat
to the biological health of the caves of the Cockpit Country. For many caves it
is too late, but not for all. Efforts should be made to reduce or eliminate
guano extraction. We will address this further in our recommendations, found in
section 4.4.
4.3.1.2.
Land-use must be considered in all cave conservation planning. The
biota of a cave is connected to the terrestrial biota found in the general area
and cannot exist independently of it. The hydrology of a cave is an integral
part of a larger system that includes surface flow. Caves deemed worthy of
protection should be considered in a larger context; the land outside of the
cave must be included in protection planning. Priority targets should have an
area of at least several hectares, outside of each entrance, that is maintained
in a natural state.
4.3.1.3.
We are aware of seven Amerindian cave sites in the Cockpit Country
(listed in the database and the notes). Three of these have extant petroglyphs:
Pantrepant Cave, Spring Cave, and Home Away Cave. The need for the preservation
of these artefacts should not be lost amongst concerns of biology and
hydrology.
4.3.2.
Vulnerable sites:
All sites have been assigned
a value that indicates the degree to which they are vulnerable to future
degradation. The values are Low, Medium, and High. The criteria is subjective
but generally uses the following method.
4.3.2.1.
Low vulnerability: Caves that are not experiencing visitation. Caves
that do not contain mixed-species bat-roosts or troglobitic invertebrates.
Caves that are not part of a hydrological system experiencing siltation. In
this category, some of the sites listed could be subject to degradation if
local land-use practices were to change - vulnerability would then increase.
The following sites have been listed in the database with this value; reasons
will be found in the notes supplied for the individual caves.

High vulnerability: Caves that have large mixed-species bat-roosts,
Amerindian artefacts, or are experiencing severe siltation. The following sites
have been listed in the database with this value; the reasons will be found
here, as well as in the notes:
APPLETON TOWER MAZE: We found Taino pottery here. The site was not
previously listed to be Amerindian. There is potential for archaeological
study. The site is in a well-populated area and experiencing visitation. |
BARBECUE BOTTOM HOLE-2: The section past the vertical pitch has a
good bat-roost, thick fluffy guano deposits, and no introduced roaches. This
is one of the two sites in the Cockpit Country that we regard as pristine. We
suggest that it be recognized as one of the more biologically valuable sites
and given whatever degree of protection is possible. |
COFFEE RIVER CAVE: Bat-roosts are found in several dark-zone areas
that we believe to consist of multiple species. Some guano extraction is
taking place. Roaches have already been introduced, but the roosts continue
to be of value. |
FARMYARD CAVE: Severe siltation. Good candidate for investigations of
methods that might reduce silt input. |
GOOD HOPE ONE CAVE - SINK: A great amount of garbage is washed into,
and through, this cave. Siltation is also great. This is a good candidate for
investigating methods to inhibit input of garbage and silt. |
GOOD HOPE TWO CAVE - SINK: We are listing this site with a high
vulnerability for the same reasons as Good Hope One. There is a great amount
of garbage being washed into, and through, this cave. Siltation is also
great. This is a good candidate for investigating methods to inhibit input of
garbage and silt. |
HARTIES CAVE #1 - MAIN: We are listing this site with a high
vulnerability due to the bat-roost and the frequent disturbance by visitors.
This cave was probably more interesting biologically in the past. We suggest
that if the guano mining were to be stopped it would be a good candidate for
monitoring of the bat-roost to see if overall numbers increase. |
HOME AWAY FROM HOME CAVE: One of the two Cockpit Country caves that
we consider pristine. Not currently visited by tourists, or people of
the district, so no immediate threat, but it is one of the few bat-roosts in
the Cockpit Country with deep, undisturbed deposits of guano. These continue
to contain paleoclimatic records. Petroglyphs are present and deserving of
protection. |
MARTA TICK CAVE: This
is one of the few relatively undisturbed bat-roosts in the Cockpit Country.
Historically, it has been of great scientific value, and in its current state
should continue to remain so. However, this state is subject to change
depending on several factors, chief amongst these being whether the track to
the cave is improved, or left as it is now. The cave, and track to it, is on
Forestry Reserve land. This gives some protection, but it could also be a
two-edged sword. If selective logging is allowed in the district near the
north end of the Marta Tick track, access will become much easier, with a
concordant increase in visitation for guano extraction. This would do great
harm to the cave. We recommend that the present conditions on the approach to
this cave not be altered, and would suggest that Forestry set aside a
protected area around the entrance to a radius of 500 metres from the
entrance. |
MOUTH MAZE - SINK: We're listing this cave with a high vulnerability,
due to the great amount of garbage being washed in and the heavy siltation.
At present, post-Hurricane Ivan, it's a total mess. The only thing comparable
I've seen is Rota Cave in St James, which also takes floodwaters full of
trash. The cave is one of the larger on the island and troglobitic species
are present. Passages conduct floodwaters to points further into the Cockpit
Country and a continuing input of plastic garbage will possibly result in
some of these being blocked by a build-up of garbage and silt. This will
impede drainage in rainy-times. Even though the cave is degraded now, it will
become worse as time passes. |
PANTREPANT CAVE: Taino petroglyphs present on stals. This site, along
with other Amerindian sites in the Cockpit Country, should be given some
degree of protection. |
PENTHOUSE CAVE - MAIN: We are listing this site with a high vulnerability
due to it having a degraded bat-roost and a history of guano mining. If local
visitation could be decreased, perhaps the quality of the bat-roost would
improve (more bats of more species). |
SPRING CAVE: As with the near-by Pantrepant Cave, Taino petroglyphs
present on stals. This site should be given some degree of protection. |
WELSCH RATBAT CAVE: We are listing this cave with a high vulnerability
because of the historical bat-roost and guano extraction, but in truth it is
degraded to the point where little more damage can be done. Nevertheless, if
visitation could be limited, perhaps by way of local education, it is a good
candidate for monitoring to see if improvement occurs. |
WILSON'S RUN CAVE: Presently mud-choked due to siltation. This is a
good candidate for investigating methods of limiting agriculturally induced
siltation. |
WINDSOR GREAT CAVE - MAIN: We are listing Windsor Great Cave with a
high vulnerability for two reasons: the possibility of the resumption of
guano extraction (and especially the damage that would be caused by this
occurring in the Main Roost); and the tourist activity that is not as controlled
as it might be. Further recommendations will be found in the notes for the
cave found in section 3.1. |
4.4.
Recommendations
The two main factors that we
have identified in the degradation of Jamaican caves are guano extraction and
local land-use practices. We will discuss below methods to mitigate the
degradation of caves due to these factors:
4.4.1.
Guano extraction, as discussed in section 4.2.1 of this report, is a
great source of cave degradation. The mining itself occurs in two forms, local
and commercial. We will address these separately, starting with local mining.
4.4.1.1.
We have found through inquiry in the districts where local guano
extraction is occurring that the main use of the fertilizer obtained is in the
production of recreational drugs, specifically ganja. To a lesser extent, it is
also used for production of food crops. We have not attempted to determine the
source of the association of "Ratbat Dung" guano with ganja
production, but, for whatever reason, it is believed to produce superior "Ital"
herb. It is not our place to comment on the pros or cons of ganja consumption,
but we can safely say that it is not a priority crop, insofar as it does not
put food on the table, or in the marketplace. At any rate, the availability of
commercial fertilizers precludes the need for bat guano fertilizer in both food
and ganja production and there is simply no reason to disturb a bat-roost in
order to supply a dubious boost to the potency of what is found in the
"spliff" being smoked by the grower.
We strongly recommend that
an educational program be initiated that stresses the importance of maintaining
the quality of bat-roosts in local caves. There are real benefits to preserving
local bat-roosts and we believe that if these were presented in a respectful,
non-demanding way, that those who are the targets of the educational program
would appreciate them. Amongst the benefits that can be presented is the role
that bats play in fruit-tree pollination and the service supplied by bats in
the reduction of local mosquito populations. We should stress, though, that if
the approach were heavy-handed it would not convince anyone; entering a
community and dictating behaviour will be counter-productive in the end. It is
our belief that education, not legislation, is the solution to this problem.
4.4.1.2.
We are not aware of commercial guano extraction taking place in the
Cockpit Country at this time, but the potential is there. Several of the listed
sites contain large deposits of fluffy guano and there is money to be made in
the export market. It should be noted that our investigations on the Internet
suggest that, again, the main use of the bat guano seems to be in the
production of ganja, in this case sold at "Hydroponics" stores and
used in indoor grow operations. Somehow, the association of bat guano with
ganja quality has reached beyond the shores of Jamaica and is now an
international phenomenon. Although we do not recommend a heavy-handed approach
to local guano mining, in the case of commercial operations, we suggest that
the Government of Jamaica legislate an end to the export of bat guano. By
focusing on export, rather than mining, the small-scale extraction done by
local farmers, for their own use, will not be legislated against, only the
commercial practices. This twofold approach, local and commercial, will result
in paths of communication being maintained with the people of the districts
where bat caves are found, while also removing the greater, but more easily
managed commercial threat.
4.4.2.
Our investigations show a correlation between local land-use patterns
and degradation. This is most obvious when it takes the form of siltation, as
discussed in section 4.2.3, but as we note in 4.3.1.2 it also has a great
effect on the biota of a cave.
We recommend that for those
sites deemed to be most deserving of protection, an area around the cave
entrance be maintained in a natural condition. The extent of this area will be
dependent on existing land-use. To minimize disruption to the residents of the
district in areas where much of the land is presently in agriculture, it will
need to be smaller than in areas currently forested.
The creation of protected
areas outside of vulnerable caves will have the following benefits.
4.4.2.1.
The creation and maintenance of a flora and fauna that resembles that
found in pre-colonial times will supply necessary habitat for the full range of
bat species that would have originally been present in the cave. Even if some
of those species are no longer there, you supply an attractive roost for them
to possibly re-colonize in the future.
4.4.2.2.
Troglophilic species (those animals that like, but are not restricted
to caves) make up a large component of the fauna of a cave. The diversity of
this group is allowed to approach the original state if the flora and fauna
external to the cave are similar to what was originally present.
4.4.2.3.
Troglobites (animals that are restricted to caves) utilize the nutrient
input supplied by troglophilic and opportunistic species. As with troglophiles,
the diversity of this group is allowed to approach the original state if the
flora and fauna external to the cave are similar to what was originally
present.
4.4.2.4.
Siltation is a factor in the degradation of caves, as discussed above
in section 4.2.3. Of the three examples we presented, it will be seen that Pool
Cave, 4.2.3.3 has a buffer of thick vegetative cover that effectively limits
silt input. The area supplying this buffer is not great, perhaps a hectare or
two (we did not measure it), but it is enough to make this the least silted
cave of all the river caves we visited in Rock Spring. For the others, the land
upstream of the sinks was in cultivation, or had been recently, and the caves
had accumulated much soft, deep mud. In the case of Farmyard Cave, 4.2.3.2, it
had been entirely filled in and no longer allowed an appreciable flow, instead
directing it above ground through a farmer's field. By maintaining good
vegetative cover upstream of a river cave, siltation is reduced or eliminated.
4.4.3.
Tourism can be a factor in cave degradation. Only one of the project
targets, Wondrous Cave, was in this state during our expeditions, but there is
the potential for this situation to worsen. It is our belief that tourism and
cave preservation can co-exist, but only if there are definite guidelines and
procedures that are followed by everyone concerned. We offer in the following
sections several suggestions for a responsible approach to cave tourism in the
Cockpit Country. (Specific suggestions for Windsor Cave will be found in
section 3.1).
4.4.3.1.
Caves that are identified as highly vulnerable because of biological
factors, such as the presence of large mixed-species bat-roosts, should not be
considered for tourism. For example, Marta Tick Cave should not be used for
tourism in any form, now or in the future. Monitoring to ensure that this is
indeed the case, perhaps combined with concurrent monitoring of the cave biota,
would be circumspect. We will discuss this further in section 4.5.
4.4.3.2.
Those caves that are deemed able to withstand some visitation, and
thusly considered for tourism, must be safeguarded nonetheless. All caves are
fragile to one degree or another. Specific methods to limit damage will be
found below.
4.4.3.3.
Smaller groups are easier to supervise. By limiting the number of tourists in a cave to three or four at
a time, you can ensure that they stay to a predefined route and do not touch
formations. We strongly recommend against taking large groups of tourists into
caves. There will be no control over what is walked on, or touched, and damage
is inevitable.
4.4.3.4.
There should be a limit to the total numbers of visitors to any one
cave over a specific period. This limit will vary according to the specific
cave, e.g. caves with bat-roosts are allowed fewer visitors per month than
caves without bat-roosts. The criteria remain to be established, but we suggest
that this approach be considered.
4.4.3.5.
Kerosene torches, such as bottle-torches, should not be used. If there
are bats present in the cave, the combustion by-products will collect at the
top of the chamber and immerse them in toxic fumes. All lighting should be electric.
4.4.3.6.
Visitors should be told to avoid shining their lights on the ceiling in
an effort to view the bats. It is our experience that if you walk quietly
through a bat-roost, with your headlamp aimed at the floor, bats tend to stay
put and not erupt into a flurry of panicked flight as is the case when several
people collectively shine their lights at them.
4.4.3.7.
A definite track should be established, and flagged, that avoids
delicate formations, guano deposits, and anything else considered susceptible
to damage.
4.4.3.8.
Caves used for tourism should have a Warden who is responsible for
supervising activities at the cave. In most cases, this will be the owner, or
someone appointed by the owner, who acts as the lead Guide for the cave. This
person should receive training that allows them to appreciate the biological
importance of caves, as well as training in safe caving techniques and rescue
methods. A first-aid kit should be available and the Warden should know how to
use it. Helmets and lights should be mandatory for guests. These can be
available for rent for guests who do not have their own.
There is little point in
having guidelines and procedures if they are not adhered to, so we suggest that
periodic monitoring take place to ensure compliance.
4.5.
Monitoring
In this report, we have
attempted to supply a snapshot in time of the general condition of the Cockpit
Country caves in the year 2005. It is intended to supply base-line information
against which future conditions can be compared. An ongoing monitoring program,
involving selected caves, could turn our snapshot into a continuum of
observations that might eventually reveal unsuspected patterns in cave
degradation and recovery.
It would be difficult to
monitor all of the caves of the Cockpit Country on a regular basis, unless
resources and personnel numbers were relatively unlimited. What can be done is
to choose a subset of representative caves and monitor these. This can be done
by using the indicators in this report, or others that seem more instructive.
The interval between visits would need to be determined by way of collaboration
between specialists, funding agencies, and field technicians, but we would
suggest that three to four times per year would be sufficient.
4.5.1.
The monitoring process itself should be non-disruptive. We suggest that
the following approach be considered.
4.5.1.1.
Passive observations are preferred for recording biological indicators,
using field examination that does not result in the death of the specimen.
Photographic records could be of help in this, allowing a detailed inspection
by specialists afterwards.
4.5.1.2.
To determine bat species, capture and release will be necessary.
Harp-nets have been used successfully in a bat-monitoring program being carried
out by the Windsor Research Centre, in Trelawny, and the same methods could be
employed at other caves.
4.5.1.3.
Degrees of siltation can be determined by measurement in selected parts
of river caves. These should include an area close to the entrance, and several
areas further into the cave.
4.5.1.4.
The quantity of garbage in the cave can be determined by counting items
of trash in designated parts of the cave.
4.5.1.5.
Access to the cave, and travel within, should be done using a definite
route that will cause the least amount of soil compaction and no damage to speleothems.
4.5.2.
Suggestions for candidate sites follow:
4.5.2.1.
The program should include several of the most vulnerable sites, with
Marta Tick Cave a priority. Other candidates are Penthouse Cave, Welsch Ratbat
Cave, and Good Hope Cave One.
4.5.2.2.
A selection of the caves that are of medium vulnerability should be
included so that patterns of degradation can be identified. Monitoring of these
sites will also indicate if they have become deserving of greater conservation
resources. There are many candidates to choose from in this group.
4.5.2.3.
Several of the sites we have designated to be at a low vulnerability
should be included so that a full range of caves is represented.

We present below a column-by-column explanation of the database that
accompanies this report (on a CD-R).
5.1.1.
A - CAVE NAME: We have included entries for multiple entrances to
caves. The rows that present entrances other than the Main Entrance have
information limited to values specific to that entrance. That is to say, we
have only included data entries for bats, etc, in the row for the Main
Entrance. This was done to reduce the amount of time needed to enter
information into the database. Additions to JU, i.e. new discoveries, are
marked **

part of the PiP Project. Excluded sites, and those not found, have coordinates
limited to the original JU coordinates, found under JU_JAD69, columns X-Z, with
accuracy unknown. WGS84, JAD69, JAD2001 columns, and all "Included"
columns, for the excluded sites have U=Undetermined, 0=Undetermined, or N/A=Not
applicable, as place-holders. (It was necessary to use 0 in the positional
columns for the sake of Arcview use of the .dbf version.) Reasons for exclusion
will be found in columns Q-S.

Perhaps
ten or fifteen hundred years ago a new tribe arrived on the larger islands of
the Caribbean Sea.
They were the Tainos, long
known as the Island-Arawaks or simply the Arawaks. Their ancestors were the
Arawaks on the mainland of South America but with the passage of time they
evolved a new culture. Their link with the mainland Arawaks was a common
Arawakan language.
They settled in the Greater
Antilles, that group of larger islands of the Caribbean Sea that comprises
Cuba, Hispaniola, Jamaica and Puerto Rico. There occupied some of the smaller
islands of the Bahamas too.
They came to dominate an area
that had been earlier occupied by the Casimiroid peoples. The descendants of these people in Cuba and
likely Jamaica belong to the Redondan subseries. Not much is known of this
earlier Redondan culture in Jamaica but that they might have lived outdoors and
in caves and though a Stone Age people might have used ceramic utensils.
The Tainos would have over the
centuries conquered, subdued or assimilated the previous inhabitants of these
territories and come in total possessions of them.
The Tainos settled into an
agricultural life-style, with hunting and fishing and trapping. It was now
their land.
They had a political structure
with village heads or kings called caciques and regions encompassing
several villages headed by a regional cacique. The cacique’s ceremonial chair
was the duho which was both functional and highly ornate.
They lived in houses made from
wood and roofed with thatch. Some of these were circular, caneys, and
some - those inhabited by the caciques - rectangular, bohios.
They were a people with time on
their hands, not always rushing out looking for the next meal. They enjoyed the
leisure of games. One of these, they played with a rubber ball on a large
rectangular court. The name of this game was batey and the rules included
using only your torso to move the ball. Use of hands and feet was illegal.
Diego Mendez who was instrumental in getting the stranded Christopher Columbus
off the island of Jamaica in 1503 owes his life to the importance of this game.
Mendez had been captured by Tainos who left him to play their ball game to
determine who would 'dispose' of him. During the game, he made his escape.
The Tainos would also use this
rectangular court for ceremonial functions including rites involving healing.
They had their healers who,
with an understanding of health and sickness and possibly their causes,
effected a physical and psychological cure.
They had a structured life. The
male and female had roles. The males for the most part hunted and fished and
females tended the gardens. They grew their root crop, cassava, on mounds of
earth called conucos akin to the modern Jamaican “yam hill” or “yam
bank”.
They used cotton trees for
making boats and the gourds from calabash trees for the making of plates and
utensils. They baked their cassava on a clay griddle, and they fashioned their
pots from clay.
They had hammocks for sleeping
and tobacco for smoking.
They often buried their dead in
caves that they would sometimes mark with petroglyphs.
They made clothes from cotton
but wore them sparsely. The women would wear a nagua, a skirt, the length of
which would vary depending on her status - the higher the status the longer the
skirt. Men would wear a loin garb.
Children would not wear clothes. Body painting was usual. Annatto was used in
this exercise. Annatto is a seed that provides a red dye.
Body piercing was also a
requisite and in these orifices would be placed feathers or jewellery,
particularly important in ceremonial activity. In order to toughen the skull, a
board would be placed against the forehead of children that also had the effect
of flattening the forehead.
In Jamaica, evidence of their
habitation has been found throughout the island, though not much work has been
done in sifting out this evidence and understanding its significance.
In Trelawny, which contains
most of the Cockpit Country, for example, over 19 sites have, at one time or
another been identified. These were places found accidentally. Not much
concerted effort has been made to find Taino sites.
Of the sites listed in this
document some are new and need further work and some have been thoroughly
investigated:
Appleton Tower Maze is newly
defined as a Taino cave with the surface finds of Bivalve shells and potsherds.
Home Away from Home Cave newly
defined with the finding of petroglyphs
Long Mile Cave excavated by Don
McFarlane
Pennhouse Shelter 1 newly
defined as a Taino Cave with the surface finds of Potsherds
Ruined Ground Cave was explored
by H E Anthony
Spring Cave was explored by the
Jamaica Caving Club in 1965 and thought to be the same as Pantrepant Cave. This
shelter cave is described in archaeological reports as Pantrepant East Cave and
is different from Pantrepant Cave.
Pantrepant Cave This is
described as 30 metres long and is referred to in archaeological reports as
Pantrepant West Cave
History has recorded that the Tainos were decimated by the brutality of the Spaniards and the diseases of the Europeans, but there are people who now say that the blood of these Tainos ‘run in their veins’. The culture has disappeared but the bloodline might not have.
