NEW MEXICO GARTER SNAKE
Thamnophis sirtalis – Linnaeus 1758
Thamnophis sirtalis dorsalis – Baird & Girard 1853
IDENTIFICATION:
DISTRIBUTION:
The New Mexico Garter Snake has never been recorded from Mexico. Habitat along the Rio Grande is highly altered by agriculture and industry, but snakes may persist along canals in the immediate vicinity of Cuidad Juarez. In the United States this snake occurs along the Rio Grande Valley from around Albuquerque south to at least Las Cruces.
HABITAT:
Historically this snake occured along the Rio Grande, inhabiting both the main river channel and any associated marshes, oxbows or other aquatic environs. In addition, it is now found around man-made impoundments, and especially the networks of canals that feed the seasonally irrigated agriculture fields that line the Rio Grande Valley.
