Recent Activities:
Effects of 7 Silvicultural Practices on Terrestrial Salamanders
in Southern Appalachian Forests
Southern Appalachian forests have one of the highest densities and diversities
of salamanders in the world. Salamanders occur in lower densities in forest
stands that have been recently clearcut. However, few studies have addressed
the effects of other timber harvesting practices on terrestrial salamanders.
The size and type of timber harvest produce different effects on wildlife habitat,
and may influence salamander populations differently. This project compares
several economically viable methods of forest management. For the past ten years,
we have monitored the effects of 7 different oak regeneration techniques at
6 sites in Virginia and West Virginia. Preliminary results indicate a decline
in relative abundance of salamanders on plots with any disturbance to the forest
canopy.

Status and Movements of the Bog Turtle in Virginia
The bog turtle is a small freshwater turtle found in isolated sphagnum bogs
and marshy meadows in the eastern United States. Habitat loss and collection
for the pet trade have caused many populations to decline and the bog turtle
is now afforded legal protection in every state in which it is found. The goals
of this study were to re-evaluate the status of known bog turtle populations
in Virginia, and to document movement among wetlands using mark-recapture techniques. We observed dispersal events of several hundred meters. We are continuing work to examine importance of habitat corridors.
Status of ecology of flatwoods salamander and Florida bog frog on Elgin Air Force Base.
The flatwoods salamander and the Florida bog frog are rare amphibians with small geographic ranges. For both species we are evaluating how habitat affects small and large scale distribution and whether current management practices are effective for these species. The maintenance of historic fire patterns and connectivity of habitats may be critical to the survival of these species, but challenging to implement.
