Carroll Cave Conservancy

Biology Project Manifesto

Last edited 6 October 2003 by Lawrence Ireland

 

The purpose of this document is to outline the policies and purposes of the Biology Project of the Carroll Cave Conservancy (CCC).  This proposal may be altered in the future with the approval of the CCC's Board of Directors.

 

The Biology Project, its manager and participants, shall:

1)       Adhere to the written policies of the CCC and the decisions made by its Board of Directors.

 

2)       Report their findings openly and objectively.

a)       All biology trip reports, and the biological data therein, shall be made public (e.g. via the CCC website, www.carrollcave.org).

b)       All biological data shall be contributed to the Cave Life Database, maintained by William R. Elliott, Ph.D.

c)       Professional expertise, from within and outside the CCC, should be sought for the purposes of analyzing and interpreting biological data, and for scientific credibility.

d)       An outline of work objectives, listing short- and long-term goals, will be prepared annually.

e)       A summary report will be prepared annually.

 

3)       Cooperate in the management of the cave in a manner that furthers and balances the goals of the CCC (i.e. "to conserve and protect" via "scientific study" while "ensur[ing] access")

a)       Biology trips will be announced and made available to all interested CCC members.

b)       The Biology Project Manager shall communicate with the Access and Restoration/Conservation committees to advise and respond to issues regarding Carroll Cave's biology and therefore the cave's conservation, including making recommendations for:

i)         Trail marking or rerouting

ii)       Visitation limitations

iii)      Passage closure

 

4)       Inventory the biota of Carroll Cave.

a)       Visit each section of the cave, typifying habitats and assessing the cave's other biotic and abiotic characteristics.

b)       Census each section of the cave, ideally before that section receives considerable caver traffic.

c)       Measure environmental conditions (preferably, simultaneous with the bioinventory).

d)       Census animals and their frequencies, using protocol from the Missouri Cave Life Survey (gross identification, with little disturbance) and, when warranted, standard biological sampling protocol (e.g. randomized quadrants, pit traps, etc.).

e)       Collect voucher specimens to identify species, when absolutely necessary.

f)        Use at least two census trips to estimate "baseline" population sizes.

 

5)       Monitor the biota of Carroll Cave.

a)       Find and collect historical data (Hawksley, Rimbach, Weaver, etc.).

b)       Incorporate observations from non-biology trips. (see also 6.b. and 6.c., below)

c)       Measure environmental conditions, including impact from human traffic.

d)       Prioritize species and/or locations that are at greater risk of impact.

e)       Re-census highest-priority species and/or locations, replicating protocol used during the initial inventory.  Some situations may call for more thorough techniques.  Care should be taken to minimize any stress imposed by the very act of monitoring itself.

f)        Scrutinize changes in population estimates (versus natural population fluctuations) and in the biotic environment; offer explanations.

 

6)       Study the biota of Carroll Cave.

a)       Research and study the natural history of Carroll Cave animals.

b)       Educate others (particularly surveyors) to be better "passive observers" in the cave.

c)       Develop and implement a standard by which others can easily submit biological observations.

d)       Accommodate and encourage further scientific research by other interested parties.

 CARROLL CAVERS:
 
 Our bio-trip last weekend sighted more aquatic invertebrates in
Thunder River's riffles!  We also noticed several isopods which were dead.
 

 In traveling what is unfortunately both Carroll's biological lifeline and its human highway, PLEASE make an effort to NOT cross streams where crossing seems natural: at the shallows.  Any place where the surface of the water "bubbles" over rocks ("rapids") will be higher in dissolved oxygen, i.e. habitat for "cave bugs" like isopods and cave snails.
 

  Elsewhere, the stream bottom is fairly sterile.  Of course disturbing the sediment is bad - any step you take that  disturbs the floor is ultimately contributing to erosion - but far worse is to trample the areas where animals make their home.  This past weekend we saw cloudiness in the water from recent rains.  Turbidity (stirred-up  sediments) is natural; human feet fording across limited, essential habitat is not.
 
  Our concern should probably be less for the cavefish and grotto salamander larvae - when rudely disturbed, they can (usually) just MOVE out of the way.  The smaller animals, prey for fish and salamanders, cannot.
 
 This trip was a highlight for us as it was our first during which we found TERRESTRIAL invertebrates.  Millipedes, mites, and springtails were found at a little oasis of food in the Round Room.  This in mind, be cautious when removing "trash" from the cave, which may be populated by TINY troglobites.
 
 At a side passage, we also found a Ptomophagus beetle in Carroll - another first.  This side passage also contained what I presume to be raccoon tracks.  I have never seen Ptomophagus beetles so far from an entrance - perhaps we have a surface connection?
 
 Andy Isbell will file our official report.  Thanks to Andy, Bill Gee, and Val Schmidt for counting fish with me.

 P.S.  Next bio trip May 10th!

 

2002/10/05 - 11:45 to 13:30 - Lawrence Ireland - 5 cavefish in 150' and 20 min. - also found first grotto salamander larva and 3 cavesnails - took temp. and humidity readings

2002/11/02 - 10:30 to 16:00 - Lawrence Ireland, Sean Ireland, and Jason Covert - found isopods, cavesnails, and 12 cavefish - took temp., humidity, and stream flow measurements

2002/12/14 - entered 13:40 - Lawrence Ireland and John McGuire dug on debris pile in preparation for ladder's footing - took temp & humidity readings

2003/02/08 - 11:30 to 21:30 - Lawrence Ireland, Dan Lamping, and Heather Levy went downstream to DL7, finding 85 cavefish while Andy Isbell, Dave McCool, and Val Schmidt went upstream to the Round Room.  I think the latter party came up with 98 fish.  Other findings from this trip are too numerous to mention here.

2003/04/12 - 12:00 to 19:30 - Andy Isbell, Bill Gee, Lawrence Ireland, and Val Schmidt repeated upstream count, but faster this time and with only 43 fish found in somewhat turbid water - found aquatic and terrestrial invertebrates - briefly inventoried a side passage
 

Common Animals

likely found in the depths of Carroll Cave

Invertebrates

Terrestrial Aquatic

Isopods - "pill bugs"; 1/8"

Isopods - dorso-ventrally flattened, like centipede, often on wood; 1/2"

 

Millipedes - grazers; about 1"

Amphipods - laterally flattened, like shrimp, usually in running water; 3/8"

 

Diplurans - 2 tails, 2 antennae; body 1/2"

Planaria - flatworms, very slow; 3/8"

Springtails - sometimes on surface of pools, often clustered; very small (1/16")

Cavesnails - occur in running water; <1/16"

 

Invertebrate Habitats:  flood debris, feces, decaying animals; high abundance and high-energy environments unlikely, but chemotrophy may be important; otherwise animals will be scarce.

 Vertebrates:

Cavefish - fairly common in Thunder River, historically in Carroll River; note observations (number, habitat, behaviors); minimize impact to stream

Salamanders - grotto or "Ozark blind" salamander; larvae have a large head and at least a white stripe down tail; adults may be beige, pink, gray, or white; any other salamander species may indicate a surface connection (see below)

  • Bats - unlikely, but pipistrelles (our smallest species) may be present; remember that clustering bats are endangered species; minimize winter disturbance

 

Animal signs of a surface connection:

          Cave flies

            Cave crickets

            Webworms

            Vertebrates

                        Cave salamanders

                        Pack rats

                        Raccoon sign

 

Be a passive speleologist!

Take a look around!

Record observations

Look for paleontological remains

Respect virgin floor; preserve sediments (a.k.a. "mud")

Your casual observations could be important!
