KARST SETTTINGS

Ground-water resources within Florida's aquifer systems, as in many other karst
hydrogeologic settings, are vulnerable to contamination due to the relatively
open flow structure in carbonate rocks. This flow structure ranges from
intergranular flow to conduit flow, as well as perforations in confining layers
due to sinkholes. In these complex hydrogeologic settings, models used in
ground-water resource protection should reflect the dynamic and "dual porosity"
nature of this flow system. Aquifer recharge and aquifer vulnerability models
often serve as the scientific basis for land-use planning decisions. Commonly
used for this purpose, DRASTIC is an expert-driven index model developed by the
U.S. Environmental Protection Agency and the National Water Well Association.
Although DRASTIC may be suitable for many hydrogeologic settings, it does not
include a component critical to the understanding of aquifer vulnerability in
Florida - karst.
The Florida Geological Survey is currently developing a geographic information
system (GIS) - based model to estimate relative vulnerability within Florida's
aquifer systems. Development of this model, the Florida Aquifer Vulnerability
Assessment (FAVA), is underway and five pilot counties have been completed with
guidance from a multi-agency advisory committee. The overall intent of FAVA is
to develop a tool for environmental, regulatory and planning professionals to
facilitate the protection of Florida's ground-water resources. The model is
based on a geostatistical method, Weights of Evidence, which quantifies
relationships between spatial data layers and water quality parameters to
predict vulnerability. For development of data layers in the FAVA model, a new,
highly resolved statewide land-surface elevation model has been developed. From
this surface model, two coverages are being created: a topographic depression
coverage to reflect proximity to karst features, and a depth to water coverage,
which is calculated relative to physiographic province. FAVA also utilizes a
statewide soil drainage coverage and a newly developed thickness of confinement
coverage. If statistics in the model justify the need, the head difference
between the surficial and Floridan aquifer systems will also be included for
confined aquifer models.
Adaptability of the FAVA model allows for refinement to reflect "local-scale"
datasets such as cave maps/conduits, lineaments, sinkhole types, and other
hydrogeologic data. Incorporation of these datasets into the FAVA model can
significantly enhance its application as a predictive tool at the local scale,
such as within a spring recharge area (springshed).

Sulphur Spring is located along the Hillsborough River in an urban area of
Tampa, Florida. Survey and water quality data were collected from the spring
cave system as part of salinity control investigation. The study was initiated
because the City of Tampa uses the spring as an emergency water source. When the
spring is pumped for water supply, the hydraulic head of the system is drawn
down and the chloride concentration of the spring discharge increases.
Therefore, water can only be pumped from the spring intermittently.
Survey data show that 25% of the surveyed passages in the cave system have a
height to width ratio greater than 1 compared to less than 10% for typical
phreatic caves in Florida. In fact, the median height to width ratio of the
Sulphur Spring cave system is 0.64 compared to 0.33 for typical phreatic caves,
suggesting some fracture controlled passage development.
Water quality data show the water in the system is well mixed. The only change
in water quality occurs at a penetration of 2800 feet where the passage splits
into the Orchid Tunnel and the Alaska Tunnel. The Alaska Tunnel has higher
temperature, lower pH, and higher salinity than the Orchid Tunnel. Based on
salinity of the two flows, about 70 to 80% of the flow is from the Orchid Tunnel
and 20 to 30% is from the Alaska Tunnel. The Alaska Tunnel appears to be the
source of the majority of the saltwater and, therefore, chloride entering the
cave system.
3. "THROUGH THE
ROOF" MONITORING WATER QUALITY IN MANATEE SPRINGS

Manatee Springs is a first magnitude spring near the City of Chiefland in Levy
County, Florida and the centerpiece of Manatee Springs State Park. In April of
2001, a local mining company initiated the process of obtaining permits to mine
160 acres on its property that is adjacent to the state park and a high density
subdivision. Significant local opposition to the mine mounted including public
protests and rallies that were covered by the media.
In its permit application, the mining company utilized a map of Manatee Springs
cave system generated in the 1980s. Subsequent exploration of the cave system
had identified conduits branching to the north and east toward the proposed mine
site, however, most of these conduits do not allow divers to penetrate into the
aquifer system very far. The exception is the "Blue Water Tunnel" named because
it remains clear when other conduits in the cave system are not. A serious sand
restriction had precluded further mapping of this conduit using back-mounted
tanks, however, cave divers utilizing side-mounted tanks pushed the restriction
and added several hundred feet to the survey. This new survey data indicated the
conduit trends to the northeast toward the proposed mine site which contains a
large karst feature.
Upon receipt of the additional cave survey data, the Park management coordinated
with the cave diving community to have water quality samples obtained from
Manatee Springs and the conduits providing flow to the spring. In August of
2001, twelve cave divers obtained water samples from nine locations within the
cave system. These samples were analyzed by the Department of Environmental
Protection's (DEP) Chemistry Lab for the following parameters- pH, temperature,
conductivity, turbidity (NTU) and nitrate/nitrite (nitrate). Subsequently, in
April of 2002, the Suwannee River Water Management District collected water
samples from the conduits and split them with the United States Geological
Survey (USGS). In addition to standard parameters, isotopic analyses are being
performed by the USGS on these samples.
The data obtained from the sampling of the cave conduit system indicates
significant differences in water quality in the individual contributing
conduits. Nitrate concentrations in the Blue Water Tunnel were found to be
nearly four times greater than those in other conduits in the cave system. These
data and the potential to gain insight into the flow dynamics of the cave system
including possibly being able to identify sub-basins within Manatee Springs'
springshed supported the installation of monitoring wells into the conduits
contributing flow to the spring. Another factor considered in the installation
of the conduit monitoring wells was the expense, logistics as well as the
potential danger to cave divers in obtaining frequent samples from the various
conduits.
In April of 2003, the land surface locations for monitoring wells that would
intersect the conduits- Sewer Tunnel, Blue Water Tunnel and the Main Tunnel were
obtained utilizing cave divers and radio location techniques. By the end of May
2003, the Florida Geological Survey completed the drilling and monitoring well
installation into the three conduits.
Water quality probes, sampling tubes and flow meters have been purchased for
each of the conduit monitoring wells and are to be installed in the near future.
Once in place, real-time water quality and flow information can be obtained
continuously.

4. RESULTS OF
SAMPLING FOR SELECTED WASTEWATER CONSTITUENTS IN GROUND WATER IN THE SILVER
SPRINGS BASIN, NORTH-CENTRAL FLORIDA
PHELPS, G.G., U.S. Geological Survey, 224 W. Central Pkwy, Suite 1006, Altamonte
Springs, FL 32714, tgphelps@usgs.gov
During January-July 2002, 35 wells in the Silver Springs ground-water basin,
north-central Florida, and 3 vents of Silver Springs were sampled for a suite of
compounds commonly found in wastewater. Of the 67 compounds analyzed, 38 were
detected, nearly all in very low concentrations. The most frequently detected
compound was the insecticide DEET (N,N-diethyl-meta-toluamide), which was
evident in 27 wells and all three spring samples. Estimated concentrations of
DEET ranged from about 0.03 to 5.8 micrograms per liter. Other commonly detected
compounds were phenol (evident in 24 wells and 2 spring samples in
concentrations ranging from 0.3 to 1.4 micrograms per liter) and bisphenol A
(evident in 10 wells in concentrations ranging from 0.05 to 4.4 micrograms per
liter).
DEET was developed by the U.S. Army in 1946 for direct application to the skin
to repel, rather than kill, mosquitoes. The U.S. Environmental Protection Agency
has determined that DEET is in Toxicity Category III (slightly toxic, the second
lowest of four categories). DEET enters the wastewater when the user bathes. The
chemical is of low solubility and does not break down easily; thus, DEET appears
to be a useful tracer for the presence of re-used water. In a karst area, such
as the Silver Springs ground-water basin, the presence of DEET in numerous
ground-water samples is indicative of the widespread recharge characteristic of
karst areas. The presence of DEET also may result from the use of septic tanks
throughout much of the basin.
The geology surrounding the wells seemed to affect the presence or absence of
DEET in the water samples; land-use type generally did not affect the occurrence
of DEET. Of the 35 wells sampled, nine were in the outcrop area of the Ocala
Limestone, the principle water-bearing unit of the Upper Floridan aquifer. DEET
was detected in all nine samples. The estimated concentrations ranged from 0.7
micrograms per liter to 0.2 micrograms per liter. Of the 35 samples, DEET was
not detected in eight samples, all of which were in areas where the Ocala
Limestone is covered by younger sediments. Samples in which DEET was not
detected were collected in the following land use types: low density
residential, commercial, crops and nurseries, tree plantations and other upland
forests. The highest DEET concentration was from a well in a commercial urban
area where the Ocala Limestone is overlain by sediments of the Hawthorn Group.
Local sinkholes may breach the Hawthorn Group confining unit, allowing surface
water to recharge the aquifer in the immediate vicinity of the well sampled.
Only one or two compounds were detected in most of the wells and spring vents
sampled; however, several compounds were detected in two wells. In downtown
Ocala, water from one well contained DEET (5.8 micrograms per liter) and 19
other compounds including caffeine (0.14 micrograms per liter). Caffeine breaks
down quickly and is considered an indicator of relatively recent recharge by
wastewater. The concentration of cholesterol, a fecal indicator, was 5.2
micrograms per liter. Phenol was detected at a concentration of 6.3 micrograms
per liter and the concentration of bisphenol A was 4.4 micrograms per liter.
Another well, located at a site formerly used as a pasture but surrounded by
residential areas, contained 3 fecal indicators: 3beta-coprostanol (2.4
micrograms per liter); cholesterol (7.2 micrograms per liter); and an estimated
detection of 3-methyl-1(H)-indole (0.23 micrograms per liter). The concentration
of nonylphenol, diethoxy- (total; NPEO2), a nonionic detergent metabolite and a
known endocrine disrupter, was estimated at 2.7 micrograms per liter. The
concentration of DEET in this sample was estimated at only 0.4 micrograms per
liter.

5. Florida
Spring Glossary and Classification System
Compiled by Rick Copeland
In the spring of 2002, a number of Florida's hydrogeologists met in Ocala and
discussed the significance and importance of protecting Florida's springs from
contamination related to man's landuse activities. Many of the participants
argued that in order to efficiently protect Florida's springs, a firm
understanding of them is critical. It was decided that a glossary of spring
terms should be developed. The Florida Geological Survey (FGS) assumed the lead
role in its development. The FGS organized a Spring Nomenclature Committee made
up of representatives of governmental agencies, the state university system,
hydrogeologists from around the state and private citizens. The glossary
consists of the most commonly used spring terms, along with their synonyms.
Whenever possible, existing terminology was taken from professional dictionaries
and glossaries. It is anticipated that the glossary will enable both the
scientific community and the public to use a set of standardized terms. During
the development stage of the glossary, it became apparent that a spring
classification system should also be developed. This newly developed
classification system is a model that enables one to envision the relationship
of one spring to the others within the state. As it turns out, all of Florida's
springs can be grouped into only a handful of different classes. This was
fortunate in that it greatly reduces the complexity in the way we think of our
springs.

William R. Halliday is NSS Honorary Member for 1955 and served intermittently on
the NSS Board of Governors for 51 years. He has published innumerable books,
papers and maps, including the first geological report and the first modern map
of Oregon Cave. As an especially influential member of the Governor's Committee
on the North Cascades, he had key roles in the creation of the North Cascades
National Park and also Glacier Peak Wilderness Area and Mount St. Helens
National Volcanic Monument. He is widely considered the prototype for Ed Abbey's
Doc Sarvis.
Jay Swofford guided at Oregon Caves National Monument for many years and knows
the cave intimately. He now is Director of Friends of Oregon Caves, and
maintains its website including the largest known research library on the cave.
The 1909 proclamation of a national monument to protect "the unusual scientific
interest and importance" of the so-called Marble Halls of Oregon was the result
of a misunderstanding; in southern Oregon and in California, marble caves now
are known to be common. Oregon Cave is not "a natural feature so extraordinary
or unique as to be of national interest and importance" and should never have
become part of the National Park System. Its 1934 transfer from the US Forest
Service to the National Park Service was an irresponsible political action; the
National Park Service was not prepared to accept responsibility for its
protection. The cave never has been managed as a scientific resource as directed
by President Taft in 1909. Until 1934 the monument was administered as a
recreational area, primarily for the benefit of the people of southwestern
Oregon. The National Park Service did not implement a management strategy until
the tour route and most of the rest of the cave were damaged beyond reasonable
expectations of restoration. It retains value as a show cave, however. Its
management should be returned to the US Forest Service for resumption of its
pre-1934 management strategy with off-trail areas designated as Research Areas
to protect possible biological and known paleontological resources not yet
inventoried. The transfer should be by Executive Order. The name Oregon Caves
National Monument should be retained.
7. Restoring
Impacted Cave Ecosystems
Timpanogos Cave National Monument
by Jon Jasper
Developing a lighted, paved trail to accommodate over 80,000 people/year has
significantly impacted Timpanogos Caves ecosystem. Several projects have been
started this year to study and remediate these impacts. New cave gates are being
installed to improve animal passage and restore natural air flows. Invertebrate
and microbe inventories are being performed to characterize the species native
to pristine cave environments. Water quality and air temperature are being
monitored to record changes from management activities. Trail drainages are
being modified to minimize the amount of sediment introduced into the cave by
visitors and employees. Surveys of bat remains and pack rat middens are being
conducted to reconstruct the undisturbed conditions. These projects should
minimize the impacts from the trails development and high visitation.

Forest
The Hoosier National Forest encompasses a significant part of the karst of
southern Indiana. Over 130 caves have been found on National Forest Service
lands including the Lost River Cave System (17 miles of mapped passages) and
Gory Hole (deepest pit in Indiana). Many caves have been given enhanced
conservation status due to their location within designated forest service
special areas or designated wilderness areas. Examples are Dillon Cave (Grease
Gravy Special Area), Gypsy Bill Allen Cave (Gypsy Bill Allen Special Area), Gory
Hole (Tincher Karst Special Area), Lost River Cave System (Wesley Chapel Special
Area) or Patton Cave (Charles Deam Wilderness Area). Proactive management
involves a detailed understanding of the caves with documentation of the complex
resources involved. Through cooperation with the Indiana Karst Conservancy caves
and karst features are being inventoried and mapped. A detailed bioinventory of
caves on the Hoosier National Forest is being conducted and is providing a
data-intensive basis for cave management plans. As a result of the cave
bioinventory over 60 species have been placed on the Region 9 Regional Forester
List of Sensitive Species. For each of these species a detailed conservation
assessment is prepared as well as an assessment of the habitat and community in
which it occurs. These assessments include a list of the caves from which each
species is known, habitat requirements, analysis of threats, conservation
actions currently being taken and provisions for the management of the species
and their unique habitats.

Inventorying Cave Features Using ESRI ArcPad Software
Timpanogos Cave National Monument
by Jon Jasper
Many locations of findings, project activities, and research in the caves have
been lost due to a lack of a good system for organizing spatial data. Using a
georeferenced map of the Timpanogos Cave System, significant features throughout
the cave such as electrical wiring, historic artifacts, rare formations, and
monitoring stations will be mapped and inputted in the field using ESRI ArcPad
software and a Pocket PC iPaq. This inventory will be organized so that spatial
relations can be studied, data can be quickly found through hotlinks, and
management activities can documented.

Brief Biographical Sketch
Dale L. Pate began his caving career in 1970 as a student at Southwest Texas
State University and became the Cave Specialist for Carlsbad Caverns National
Park beginning in July 1991. He has continued in that position through the
present. Duties for the position include direct involvement with park management
concerning Carlsbad Cavern and supervision of all entry into Lechuguilla Cave.
The direction of his paper is a summation of the cave management program that
has evolved at the park.
Abstract
Carlsbad Caverns National Park in southern New Mexico contains some of the
world's most spectacular, yet fragile, cave resources. The cave management
program that has evolved at the park strives to balance protection,
preservation, and conservation of these non-renewable resources with access at
varying levels for recreational and educational values, and scientific research
and management needs. The tour routes in Carlsbad Cavern with a yearly average
of 500,000 visitors and the management of Lechuguilla Cave with its current
length of over 110 miles (177 kilometers) are examples of the different
management challenges faced by the park. This paper will present a look at the
current programs that help achieve the balance mentioned above.
11. THE IMPORTANCE OF KEEPING DUPLICATE RECORDS
Jerry L. Trout, National Coordinator / Cave Resources
As more and more individuals and/or groups become involved in cave management as
employees, volunteers, researchers, etc., it has become increasingly important
to maintain an accurate accounting of information accumulated in cave files and
to have duplicate files at a different location. It is well known that often the
greatest impacts to cave resources are activities such as surveying,
photography, inventory and various types of research. Meticulous record keeping
and a system that safeguards such information must be established in order to
minimize duplication of efforts to collect data for cave files. History has
shown that a duplicate set of files is often the best insurance against having
to redo information and data collection.

I have reviewed over twenty-five years of census data on gray bats, Myotis
grisescens, from Missouri's Natural Heritage Database and Cave Life Database.
The data were taken in numerous caves, both gated and ungated. Examination of
the census data and information on cave structure, type of management, type of
gate and other factors shows that cave gates are not always needed to protect
this species. However, a proper cave gate often is needed if there is no
vigilant owner or manager living nearby, and the cave is vulnerable to
unauthorized intruders. Vulnerability arises from different factors, but public
ownership is an important one. I shall present several case histories and graphs
to illustrate typical and extreme situations for maternity colonies. A summary
graph will also be presented. Despite my findings, we utilize the latest cave
gating techniques to protect important, vulnerable gray bat caves. That is why
Missouri now has the first and second largest cave gates at Rocheport (Boone)
Cave and Great Spirit Cave, respectively. A Missouri Cave Gate Working Group is
being established to bring together cave owners, state and federal agencies,
cavers and conservationists who can work together on cave protection issues and
funding.

13. QUANTITATIVE REAL-TIME PCR ASSAYS OF BACTERIAL DNA IN SEDIMENTS OF THE
FLINT-MAMMOTH CAVE SYSTEM WITH EVIDENCE FOR NITROSPIRA SPP. AT SITES UNDERGOING
LIMESTONE DISSOLUTION AND KARST AQUIFER EVOLUTION
RICK FOWLER, ELI ROBERSON, AND SHIVENDRA SAHI BIOTECHNOLOGY CENTER, DEPARTMENT
OF BIOLOGY, WESTERN KENTUCKY UNIVERSITY, BOWLING GREEN, KY 42101
Quantitative Real-Time PCR (qRT-PCR) is used to compare the densities of
eubacterial 16S rDNA in sediments from the Flint-Mammoth Cave System while DNA
sequence information and restriction fragment biomarkers demonstrate the
presence of Nitrospira spp. in bacterial communities. Thirteen samples were
collected from sites with a range of hydrologic conditions and compared with
respect to nanograms of DNA per gram of sediment by amplification of
environmental DNA relative to E. coli genomic DNA with universal primers for
eubacterial 16S rDNA. Saturated clastic stream sediments where the process of
limestone dissolution and cavern enlargement processes were active displayed
high DNA levels with the associated presence of a eubacterial clone closely
related to Nitrospira spp. Two sediment samples from an inactive and dry cave
environment were assayed and shown to contain 45 ppm nitrate, but were negative
for detectible bacterial DNA. It is concluded that Nitrospira spp. are
associated with bacterial communities in actively evolving karst aquifers and
may contribute to cavern enlargement by consumption of carbonate minerals as
chemolithoautotrophs in the absence of other carbon sources in the cave
environment. Also, nitrates in dry sediment do not appear to be attributable to
active bacterial nitrification.

14. Mercury and methylmercury in karst ecosystems and its potential effects
on vulnerable biota
Kurt Lewis Helf, Ph.D.
Long-Term Ecological Monitoring Program
Division of Science and Resources Management
Mammoth Cave National Park
Toxicity and bioaccumulation studies of mercury (Hg), the most toxic
nonessential heavy metal, on karst ecosystems are virtually nonexistent.
Available data suggest organisms at higher trophic levels generally biomagnify
Hg at a similar rate and, once it is stored in their tissue, excrete it very
slowly. Further, biota with a slow metabolism and long life span likely
bioaccumulate high levels of Hg. The data presented here are studies of other
nonessential heavy metals taken from extensive literature searches. Bats are
vulnerable to Hg bioaccumulation because they are mobile and generally consume
40-100% of their body mass in prey each night. Bats that feed heavily on
emerging aquatic insects (e.g., Trichoptera), which spend their larval stages in
contaminated sediments, are particularly susceptible to biomagnification of Hg.
Bats exposed to cadmium have been found with damage to their heart, kidneys, and
lungs. Another study indicated cadmium concentration was higher in a troglobitic
(i.e., obligate cave-dwelling) crayfish (i.e., Orconectes australis australis)
than in a troglophilic (i.e., facultative cave-dwelling) crayfish (i.e.,
Cambarus tenebrosus). The authors also attributed significantly higher (p<.05)
concentration of nonessential metals in almost all O. a. australis tissues,
relative to C. tenebrosus, to its increased longevity. A vigorous research
program on the toxicity and bioaccumulation of Hg would enable wildlife managers
to better predict the effects of future increases in Hg deposition on vulnerable
biota.

Development of an Index of Biological Integrity for Endangered Species
Monitoring in Southern Illinois

The Illinois cave amphipod, Gammarus acherondytes, is known only from caves in
the karst of Monroe County in southwestern Illinois. Extirpated from the one
cave where the amphipod was formerly found in adjacent St. Clair County and
apparently declining across the rest of its narrow range, in 1999 the Illinois
cave amphipod was added to the U.S. Endangered Species List. A yearly census of
caves in all groundwater basins in which the Illinois cave amphipod remains is
sponsored by the U.S. Fish & Wildlife Service to monitor the species. The census
data is being analyzed in a number of ways, including the development of an
index of biological integrity (IBI) for cave stream invertebrates. The IBI is a
biomonitoring protocol that was first published in 1981 using data on fish to
characterize the degree of human impact on surface streams. The variables
(metrics) in the IBI were chosen as indicators of the level of impact. The
protocol has been modified to adjust for regional differences and other kinds of
aquatic communities. In the Mammoth Cave area an IBI was developed by Thomas
Poulson and William Pearson primarily using metrics concerning cavefish and cave
crayfish. Neither of these organisms is present in Illinois caves, thus
presenting a challenge in creating metrics that use data primarily concerned
with amphipods, isopods, snails or flatworms. A preliminary IBI for cave
communities in southwestern Illinois incorporating data for 10 metrics has been
constructed and is undergoing testing.
16. Philip L. Moss and Thomas Aley, Ozark Underground Laboratory, Mapping
Presumptive Habitat for Subterranean Aquatic Species of Concern in Management of
Karst Areas.
Generally, populations of species of concern are located by direct observation
or capture. This is a severe limitation when dealing with cavernicoles, since a
very small percentage of potential habitat is accessible to investigators. The
Ozark Underground Laboratory is promoting the concept of presumptive habitat;
that is all groundwater that has subsurface hydrological interconnections should
be presumed to contain the aquatic species of concern that are found in
accessible parts of the groundwater system and that the entire groundwater
system be managed accordingly. Groundwater tracing using fluorescent dyes is a
powerful, empirical tool for delineating groundwater basins and demonstrating
hydrological interconnections between groundwater basins. The recharge are
boundaries representing known and presumptive habitat are important tools for
biological analysis and conservation management. Dye traces help evaluate tested
portions of the groundwater system; dye passes readily only through relatively
open conduits; a significant requirement for most aquatic cavernicoles. Aquatic
cavernicoles can generally move against the hydraulic gradient and cross
drainage divides under more variable flow conditions than does tracer dye. The
migration of fauna against the hydraulic gradient permits more gene flow than
may be suggested by dye tracing.

We documented the nocturnal foraging range of the cave cricket Ceuthophilus
secretus (Orthoptera: Rhaphidophoridae) at a cave in Coryell County, Texas.
During 17 nights between 8 May and 10 July, 2003 we marked more than 1000
emerging crickets at the cave entrance with UV-bright paint. Using battery
powered ultraviolet lights, we searched the area around the cave logging our
search path with a GPS receiver. Over the course of this study, 291 marked
crickets were located. Preliminary analyses show that the crickets were found at
38.5 meters from the cave on the average, with distances varying from 2.3 meters
up to 105.7 meters. Ninety percent of the crickets were found within 72 meters
of the cave entrance. Crickets were active from about 9 pm to at least 3 am.
Ceuthophilus secretus is important in central Texas cave communities because it
brings significant energy into the cave through its' surface forays. On the
surface, the Red Imported Fire Ant (RIFA), Solenopsis invicta, is an important
introduced predator. Possible interactions (competition and/or predation)
between cave crickets and RIFA could, therefore, have significant impacts on
cave communities. Thus, the foraging range of the cricket has significance for
land managers who may wish to control RIFA populations around caves that contain
federally endangered terrestrial cave invertebrates.

Biography
Joey Fagan started caving in 1966 in Virginia. He works as a Karst Protection
Specialist for the Virginia Department of Conservation and Recreation Division
of Natural Heritage Karst Program. Joey currently serves as the Secretary of the
Virginia Cave Board. He is one of the founding members of the Blue Ridge Grotto,
a member and Conservation Chair of the VPI Cave Club, and active in the Virginia
Region of the NSS. He was VAR Conservation Chair and Secretary/Treasurer during
the 70's as well as a past Director of the Cave Conservancy of the Virginias and
of the Virginia Speleological Survey. He serves as the Caving Coordinator for
the Girl Scouts of the Virginia Skyline Council Adventurers Program and is on
the NSS Youth Group Liaison Committee. Joey has been a member of the NSS for
more than 35 years and became a Fellow of the Society in 2003.
Good things can happen when diverse groups of people work together. This is one
example. The Girl Scouts of the Virginia Skyline Council Adventurers have
provided many opportunities to educate young people and the public about the
importance of cave conservation and karst sourcewater protection. Involvement
with the Adventurers began with a few Girl Scout Caving Trips led by the author
with assistance from members of the VPI Cave Club. Presentation of a strong
safety and conservation message and basic information on cave science was a
major element of every trip. Over the years, as the program's reputation
gradually became established, opportunities to spread the word about karst-related
environmental issues presented themselves. Occasional feature stories in area
newspapers provided an excellent venue to inform the public about why karst
sourcewater protection and cave conservation are essential. The scout trips
continued at a rate of two or three trips per year. The aim was to allow small
groups of motivated young people to learn about and experience caves without
appreciably increasing the number of new cavers. One particularly enjoyable
media experience was a project to produce a piece on the Adventurers Caving
Program for the National Geographic Today Show. The National Geographic
Television segment delivered a strong cave conservation message to a national
audience. A recent project to clean out a trash dump from Nellies Cave in
Blacksburg, Virginia involved cooperation between girl scouts, members of the
Virginia Region of the NSS, local and state government agencies and the news
media.

Congressional legislation directed the National Park Service (NPS) to establish
the National Cave and Karst Research Institute in the Carlsbad, New Mexico, area
to facilitate speleological research, enhance public education, and promote
environmentally sound cave and karst management. The legislation further
requires that the NPS jointly administer the Institute with a public or private
agency, organization, or institution.
The Institute has a national, even international, mission. Currently, Institute
funding comes from two sources: The National Park Service and the State of New
Mexico. As the Institute must at least equally match federal funds with
non-federal funds, an important issue for the success of the Institute is
establishing an extended network of non-federal funding sources, which might
include non-federal grants, partnership initiatives, fee-based services, product
sales, and public donations.
Determining the exact functions and organizational structure of the Institute
within these requirements constitutes a major component of the current Gearing
Up phase. The Institute staff has made major strides in extending the base of
participants in this effort over the last six months, involving major academic,
government, and non-profit organizations and several national laboratories
nationwide. The goal remains to develop a broad coalition of diverse cave- and
karst-related partners working together towards improving our national
understanding and stewardship of these sensitive terrains.

Biography: Kriste Lindberg has been an active member of the caving community since 1992, mainly in the fields of conservation, education, and interagency cooperation, having been introduced to it while working with the Chicago Academy of Sciences after receiving a BGS and MSEd in natural resources. She has served on the Indiana Karst Conservancy board as a Director, Secretary, and President, is currently a Director and Chairs the Education and Outreach Committee, which she created. She is employed by both the City of Bloomington’s Parks and Recreation and Utilities Departments as an Education Specialist, has recently been appointed by the Mayor to serve on Bloomington’s Environmental Commission, and has done numerous articles and presentations for cave-related venues, including the NCKMS 1999, 2001. In 2002, she received the NSS Conservation Award and was honored as Fellow of the NSS. In 2003, she was elected to the board of Project Underground.
Abstract: Partnerships are helpful, if not essential, for karst protection. As the use of such areas is on the rise, particularly in the way of development, increased efforts need to be made to protect it. This can pose a challenge, mainly as those involved may see things differently. However, steps can be taken to help bridge the gap. Education is a valuable tool in this endeavor as it has the potential to assist parties in reaching understandings without feeling threatened. Thus, increasing cooperation, decreasing duplication of effort, and inviting camaraderie. For example, Lindberg has brought many together for their mutual benefit by presenting them with the knowledge they need to understand karst areas and how and why it is important to work together for its, and their, protection. She has found that working with them has produced positive results. Serving as a liaison between area agencies, land trusts, planners, developers, the public, etc., she has helped them see how karst areas function – just because their features may be out of sight, they should not be out of mind. In the City of Bloomington, Indiana, efforts are being made to help all understand the way karst fits into daily life. For example, inter-related programs involving natural (karst) and man-made (storm drain) drainage systems have been developed and are being implemented. They include initiatives with Hoosier Riverwatch, Project Underground, storm drain marking programs, and so on. Viewers will learn not only what is being done but also how to go about doing it.

Biography: Carol Zokaites started caving in 1973 while attending Virginia Tech.
She participated in many cave mapping and conservation projects. She has helped
create several karst publications including "Living On Karst," educational
materials for the IMAX film, "Journey into Amazing Caves," and the guidebook for
the 1995 NSS Convention "Underground in the Appalachians." Carol is a Fellow of
the NSS and has received the NSS Conservation Award. She is now the National
Coordinator of Project Underground and Karst Education Coordinator for the
Virginia Department of Conservation and Recreation.
By the early 1990's, it became apparent that Virginia needed to protect its
karst landscape. Twenty-seven Virginia counties depend heavily on karst aquifers
for water supply. Industrial, agribusiness, and rural residential development
were placing increasing stress on karst aquifers already impacted by traditional
agricultural land use. The problem was convincing government agencies and local
citizens of the need for karst groundwater protection. Education proved to be
the solution. This paper examines the many ways education has furthered the
cause of karst protection in Virginia. Educational materials from government
agencies and the caving community have increased citizen awareness of Virginia's
karst resources. The Cave Conservancy of the Virginias produced the widely
distributed book Living on Karst, which explains basic karst science in layman
terms and makes a strong case for karst protection. The Virginia-based Project
Underground curriculum brought karst issues into primary and secondary school
classrooms, as well as to environmental educators at museums, state parks, and
soil and water conservation districts. The bench-scale karst groundwater model,
produced by the University of Nebraska - Lincoln, is a visual tool that
demonstrates surface water and groundwater interactions in karst. Numerous
Virginia agencies and non-profit organizations now use this model. Numerous
presentations and workshops have helped planning district commissions, local
governments and state and federal agencies create new standards and ordinances
protecting karst watersheds. Ten years ago most citizens in Virginia's limestone
regions had never heard the word karst. Today, awareness of karst is widespread,
and stakeholders are taking concrete steps toward karst protection.

The Western
Kentucky University Source Water Protection Program: Educating Water Resource
Managers and the Public about the Vulnerability of Rural Karst Drinking Water
Supplies

Bowling Green, KY 42101
Since 1998, the Western Kentucky University Technical Assistance Center for
Water Quality, with funding from the US Environmental Protection Agency, has
been working to provide technical, managerial, and financial assistance to rural
drinking water providers in Kentucky. To improve public health within Kentucky,
the Center's Source Water Protection Program assists water providers, their
customers, and other local stakeholders with an approach that assumes that
better the quality of source water when it reaches the treatment plant, the
easier and cheaper is to treat.
The roughly 50% of Kentucky underlain by karst aquifers present special
challenges as these waters are especially vulnerable to contamination by rural
land use, including bacteria, pesticides, and nutrients. Since land use is
closely tied to groundwater quality in these areas, education about the
functions of such systems can be a powerful tool for protecting vulnerable
drinking water sources. A major component of this program provides education to
landowners, local government officials, utility managers, citizens groups, and
the public about source water issues.
This poster describes educational tools we are developing, with the module
Impact of Karst on Source Water Protection as an example. Similar to other
modules in the program, this has been designed as a workshop, but also includes
printed materials and a website for wider dissemination. Subsections of the
module include Concepts of Source Water Protection, Karst Landscapes and
Aquifers, Karst Related Environmental Problems, Best Management Practices for
Source Water Protection in Karst, GIS in Source Water Protection, and
Partnerships for Source Water Protection.
A Systems Approach
for the Understanding of Agricultural Contaminant Sources and Transport within a
Karst Groundwater Drainage Basin
Patricia Kambesis
Hoffman Enivornmental Research Institute
Western Kentucky University, Bowling Green, KY
The sources and transport of pesticides, nitrates and bacterial contaminants in
an Iowa karst groundwater basin will be determined using isotopic analysis,
antibiotic resistance analysis, and general water quality testing, coupled with
a detailed evaluation of the extent and land use of the recharge area, and
surface and groundwater movement in the basin. The basin under study is a
shallow karst aquifer in an agricultural area of northeastern Iowa and southern
Minnesota. Previous analyses of water quality results have shown that both
surface streams and groundwater within the basin contain anomalously high
concentrations of nitrates, waste-related bacteria, and pesticides. The high
nitrates imply that sources other than soil organic matter have contributed
nitrates to the shallow karst aquifer. High fecal coliform levels suggest an
influx of waste products from humans and/or livestock and/or wildlife. Pesticide
levels in the study area fluctuate seasonally and are a reflection of seasonal
application on row crops. Water quality testing conducted during normal and high
flow conditions indicates that contaminant movement through the basin is rapid
and temporary degradation of water quality is significant after storm events. In
order to address these problems of contamination of karst aquifers, a systems
approach is required in which the function of the aquifer and its relationship
to the recharge area, and the sources of contamination, are considered
separately and as integrated parts of a karst groundwater study. The development
of effective management practices to preserve water quality, and remediation
plans for areas that are already polluted, requires identification of the actual
sources of contaminants and understanding of the processes affecting local
contaminant concentrations. In particular, a better understanding of hydrologic
flow paths and solute sources is required to determine the impact of
contaminants on karst groundwater basins.
Survey of
Microbial Diversity within Wind Cave Using DNA Analysis, Wind Cave National
Park, South Dakota
Rolland E. Moore
Western Kentucky University
Bowling Green, Kentucky
Microbiology is one of the newest frontiers in cave research. Cave bacteria have
been shown to influence primary speleogenesis by raising carbon content and
producing higher acid levels in streambed. Also they precipitate or influence
the formation of secondary mineral deposits. The major problem in studying cave
bacteria is that they evolve and live in inter dependant communities and most
often cannot survive alone. This is a problem for traditional microbiologist
because they need to isolate and culture individual bacteria to be able to study
them. Using DNA analysis techniques allows us to study bacteria that cannot be
cultured in addition to making possible new types of analysis. Currently there
is a need for a broader background database before specific research can be
meaningfully conducted or reliable. Genetic fingerprinting is ideal for creating
this background database because it is economical for use on a large scale and
enables us to distinguish species within a community. Using this technique in
conjunction with real time PCR quantitatively monitor unidentified species
within karst microbial communities.

22. Indiana bat
hibernation caves: restoration as a step beyond conservation.
Jim Kennedy, Cave Resources Specialist, Bat Conservation International, Post
Office Box 162603, Austin, Texas, 78716-2603. 512-327-9721. jkennedy@batcon.org
The Indiana bat (Myotis sodalis) is a federally-endangered species reliant on
very cold Eastern caves. Many historic roosts are no longer suitable due to
saltpeter mining, commercial development, and excessive disturbance. Disturbance
can be controlled through well-designed gates and other protective measures.
However, physical changes to the cave, such as enlarging passageways and
modifying entrances, can alter the microclimate inside the cave so that it is no
longer suitable for Indiana bats, even with gating. In 1998 Bat Conservation
International and the U. S. Fish and Wildlife Service began a long-term project
to monitor and better characterize the temperatures and microclimates of some of
the most important current and former roosts. This led to the discovery that
many of the sites we felt were important and protected, were in fact marginal
roosts that the bats retreated to when their primary roosts were no longer
available or suitable. Other formerly important sites were not even recognized
as such. Further microclimate research in one cave, Saltpetre (Carter County,
Kentucky), led to a predictive model of changes in microclimate throughout the
cave system and throughout the year. This summer the first modifications to
restore former habitat conditions were completed. Impacts to tourism and
cultural material had to be considered. Microclimate monitoring and future bat
counts will help us adjust our modifications to achieve the desired 3°C drop in
the overall cave temperature.
AUTHOR BIO: Jim Kennedy has worked as a camp counselor, environmental educator,
and Interpretive Director at Laurel Caverns, a show cave. He began working with
bats as a non-game wildlife technician for the Pennsylvania Game Commission. For

23. Rick
Olson, DON'T MESS WITH MAMMOTH DAYS in the Pike Spring Basin of Kentucky
"Don't Mess With Mammoth Days" is a cooperative effort among private and
governmental organizations to clean up groundwater recharge of the Pike Spring
Basin in and near Mammoth Cave National Park. In alphabetical order, the
organizations consistently involved are the Cave Research Foundation (CRF), Hart
County Solid Waste (HCSW), Mammoth Cave National Park (MCNP), and the National
Speleological Society (NSS). It is important to keep in mind that the horsepower
within these organizations is provided by people who match their rhetoric with
hard work. Bill Hack, the previous director of HCSW, was particularly helpful in
getting this project off the ground.
24. Ecosystem
Management and the Idea of Cave Wilderness In Protecting Karst Resources
Patricia E. Seiser, PhD
NSS 28650 FE
Findings from a recent study on the idea of cave wilderness indicate the need
for an ecosystem management approach in the stewardship of cave and karst
resources.
In planning for the use and allocation of, as well as the protection of, natural
resources, land managers must consider both social variables and biophysical
factors. The sole use of ecological information in the protection and
restoration of natural resources, such as karst aquifers, may be self-limiting,
as it does not present a holistic understanding of an area and its resources.
This paper will explore using an ecosystem management framework and the idea of
Cave Wilderness in protecting karst resources.
