|
The long-term persistence of ornate box turtles (Terrapene ornata ornata) will require effective conservation and management strategies informed by scientific investigations. Given the extent to which preferred ornate box turtle habitat has declined and become fragmented, population-level conservation decisions will be critical. In Illinois, where ornate box turtles are threatened, an isolated population resides in a relict sand prairie (Carroll and Whiteside Counties, IL) used highly by humans and managed through controlled burns and vegetation removal. Previous analyses of mark-recapture data for this population from 1996 to 2003 estimated a recruitment rate (l) of 1.02 (±0.06). Genetic diversity was also previously analyzed and found to be similar to that of a larger reference population in Nebraska, despite evidence of a recent bottleneck. Preliminary results indicate that individuals use the habitat non-randomly, with preferential use of woody trees and shrubs during hot mid-summer days. Information from further investigations of habitat use, along with previous demographic and genetic data will be used to develop a suggested management plan for this population.
