  • State Listing Status Sensitive


Special needs

Western rattlesnakes are found in dry areas with low or sparse vegetation. They often use rocky areas for basking, cover, and den sites/hibernacula.

Limiting factors

Widespread habitat loss represents a significant and broad threat to this species. Lack of exposed bedrock may be limiting in some areas. Persecution of rattlesnakes by humans can deplete or eliminate populations locally.

Conservation actions

Maintain or restore low grassland habitat near rocky areas. Minimize disturbance at key den and hibernacula sites.
