Rattlesnake Exploration Database
The Rattlesnake Conservancy Species Database is a tool that can be used by the public, researchers, government, private herpetoculturists, and the like to find information on the status of rattlesnakes in their state or country. This database is searchable by any field below. We are constantly updating this database, so if you see an error or missing data, please send us a message or email us at !
We are also developing an interactive map that shows the range of all known rattlesnake species in the New World (the Americas).
Least concern - current information indicates this species is not in need of immediate conservation action to prevent extinction
Declining - current information indicates that this species is markedly declining due to various factors, such as rattlesnake roundups, climate change, indiscriminate killing, habitat destruction, fragmentation, lack of habitat management, and/or other natural and manmade features.
Crotalid of Special Concern - Species of rattlesnake that have been identified by TRC as needing proactive conservation measures to prevent becoming imperiled.
Imperiled - Species of rattlesnake that have an immediate threat of extinction or have a small endemic range without a resilient population.
