Eastern Ribbonsnake

The Eastern Ribbonsnake (Thamnophis sauritus) is listed as 'Threatened' under both the federal Species at Risk Act and the Nova Scotia Endangered Species Act.  Its range in Nova Scotia appears to be limited to the interior of southwest Nova Scotia, with the majority of sightings occuring in the Mersey and Medway watersheds. Little is known about this small, harmless, cryptic snake.  Researchers are studying the Eastern Ribbonsnake to determine its range in Nova Scotia, its population structure, size and trends, and to better understand threats. Threats include loss of habitat due to shoreline development, alterations to watercourses, being run over by vehicles on roads, tracks and trails, and being intentionally harmed by humans. Our limited understanding and lack of knowledge of its biology, distribution, and overwintering sites may be the greatest hindrance to its recovery.
