The Nature Conservancy in Mississippi Camp Shelby Conservation Program Melinda R. Lyman, Matthew G. Hinderliter and James R. Lee Louisiana Quillwort Camp Shelby Overview (Isoetes louisianensis Thieret) LONGLEAF PINE ECOSYSTEM FEDERAL AND STATE ENDANGERED Comprises 134,000 acres within the Longleaf pine ecosystem of Mississippi Monitoring Threats -Anthropogenic and natural -Part of the USFS DeSoto Ranger District which comprises over 500,000 acres of Longleaf pine forest. -Rare ecological communities -Federal and State listed flora and fauna Population Viability & Growth Study -Fill in data gaps in determining future status -Measure variables that influence adults and sporelings to determine potential long term impacts -Five study sites associated with four different M. Lyman/TNC watersheds -Can be potentially incorporated in models used to predict population viability On-the-Ground Science -Monitor, evaluate and communicate threats -Research related to rare species life history and the effects of habitat management M. Lyman/TNC M. Lyman/TNC Camp Shelby Burrowing Crayfish Black Pine Snake Gopher Tortoise (Fallicambarus gordoni Fitzpatrick) (Pituophis melanoleucus lodingi Blanchard) (Gopherus polyphemus Daudin) FEDERAL CANDIDATE, STATE ENDANGERED FEDERAL CANDIDATE, STATE ENDANGERED FEDERALLY THREATENED, STATE ENDANGERED Candidate Conservation Agreement Life History & Ecology -(USFS, MSARNG, USFWS & MDWFP) -Alleviate threat of changing listing to threatened or endangered -TNC scientists perform the monitoring -Telemetry of adult and juvenile snakes to determine habitat usage, refugia types along with seasonal activity, mating and nesting patterns -Response to restoration activities Provide habitat management recommendations J. Lee/TNC -Implement adaptive management -Prioritize areas in need of restoration or other habitat improvements -Monitor and communicate other threats such as wetland disturbance Burrow densities & Habitat conditions -Open Condition (Most favorable) -Moderate Condition -Shrub Dominated -Bottomland Hardwood (Least favorable) Other Camp Shelby burrowing crayfish projects -Population genetics study (collaboration with USFS and Carnegie Museum) Candidate Conservation Agreement (in review) -(MSARNG, USFS, USFWS, MDWFP, other agencies being approached) -Proactive approach to alleviate threat of changing listing to threatened or endangered -Includes monitoring of the snake and habitat conditions to implement adaptive management Other Black pine snake projects -Collaborative study of habitat usage on federal lands vs. private lands -Potential implementation of Candidate Conservation Agreements with Assurances (for private land owners) -Increase the protected area for the Black pine snake as well as associate species on a landscape level J. Lee/TNC Juvenile gopher tortoise -Telemetry at different ages to determine growth, home range, burrow use and construction, movement pattern, cause and extent of mortality Predator-proof enclosure M. Lyman/TNC -Holds hatchlings until they reach the desired age for field tracking Current cause and extent of mortality -Majority of predation by mammals and fire ants -Mammals prey on all ages of juvenile tortoises -Fire ants almost exclusively prey on hatchlings (<1 year old) -Metabolic bone disease (MBD) observed from tortoises placed in the head start pen after 2007 (thought to be related to pen conditions receiving repeated dormant season burns). Collaborative work looking closely as this is currently being initiated. Movement and activity patterns, home range, growth and burrow use data are currently being analyzed.
