Conservation reassessment of Mexican reptiles Rhadinaea laureata. The endemic crowned graceful brownsnake is distributed along the Sierra Madre Occidental from west-central Durango southward into the Tranverse Volcanic Axis as far as central Michoacán, Morelos, and the Distrito Federal. Its EVS has been calculated as 12, placing it in the upper portion of the medium vulnerability category, and its IUCN status has been determined as Least Concern. This individual is from Rancho Las Canoas, Durango. Photo by Louis W. Porras. Thamnophis mendax. The endemic Tamaulipan montane gartersnake is restricted to a small range in the Sierra Madre Oriental in southwestern Tamaulipas.
