| Abstract |
|
Testudinidae Gopherus polyphemus address some of the problems associated with surveying gopher tortoise burrows to determine the number of tortoises present at a site. We monitored 50 gopher tortoise burrows for two months at Archbold Biological Station and recorded the number of times a burrow changed its perceived condition. Burrows first judged to be active were active on more days than those first judged to be inactive or abandoned. Rainfall on the day of a survey caused more burrows to be judged inactive. The physical structure of the microhabitat immediately outside a tortoise burrow reflects the perceived condition of the burrow.
