Plains Gartersnake (Thamnophis radix) - Ohio Herp Atlas

Plains Gartersnake Thamnophis radix - Endangered

Strange as it may seem, Ohio has an isolated colony of Plains Gartersnakes. These brightly marked gartersnakes occur only in Wyandot County, in the vicinity of the Killdeer Plains Wildlife Area where they inhabit remnants of what was once the most extensive wet prairie in Ohio. A distinctive feature is the lateral stripes along the third and fourth rows of scales. Their dorsal stripe is more orange than their yellow lateral stripes. This snake is designated as state endangered. LENGTH: 18”–24”
