The Timber Rattlesnake (Crotalus horridus) is one of two rattlesnake species occurring within the state of Ohio. It is listed as an endangered species by the Ohio Department of Natural Resources Division of Wildlife. In Ohio, this species formerly occupied 22 counties across the eastern and central regions of the state. It occurred as far north as the Lake Erie islands. Today this species is restricted to 8 counties in southeastern Ohio. Timber Rattlesnakes occupy a variety of habitat types across their range. However, they prefer rocky oak/hickory deciduous forests in the rugged hills throughout southeastern Ohio.
Habitat assessments for Timber Rattlesnakes can be performed throughout the year and require walking throughout the project footprint. These assessments involve identifying suitable hibernaculum, gestation, and foraging habitat features. Construction monitoring and visual encounter surveys for Timber Rattlesnakes can be conducted between April 15th and October 31st.
EDGE’s professional herpetologist, Mr. Aaron Crank, is authorized to conduct Timber Rattlesnake surveys and habitat assessments within Ohio. He has extensive experience surveying this species throughout its range. Additionally, he has conducted relocation efforts during active construction. If evaluating and managing potential disturbances to Timber Rattlesnakes is critical to the success of your project, please reach out to Aaron for #furtherinsight.
