Wildlife Programs: Amphibians and Reptiles

Blacksnake Along the trails, visitors may encounter such creatures as frogs, toads, turtles, lizards, and salamanders. Trail walkers may even see a few snakes during the warm months. The Clinch River Environmental Studies Organization (CRESO) has put together lists of the reptiles and amphibians that they have inventoried on the Arboretum property.
