The Eastern Hellbender (Cryptobranchus alleganiensis) is one of the largest amphibian species in the world, with some individuals growing to over 27 inches. This species formerly occupied 25 counties across the state and is now restricted to less than 10 counties in Ohio. Eastern Hellbenders are fully aquatic and require cool, fast-flowing, rocky streams and rivers. Eastern Hellbenders are protected as an endangered species by the Ohio Department of Natural Resources Division of Wildlife.
Habitat assessments and construction monitoring for Eastern Hellbenders can be performed throughout the year. Visual encounter surveys for Eastern Hellbenders should be conducted during the active season from May through October.
