The United States Fish and Wildlife Service has proposed listing both the Rim Rock crowned snake and the Key ringneck snake as endangered under the Endangered Species Act. According to the service, there will be no habitat left for both snake species by 2080 in the lower Florida Keys and they will potentially perish without action. The Rim Rock crowned snake is considered to be North America’s rarest snake. An individual was photographed after it had died trying to eat a centipede.

The service has also proposed to protect 2,604 acres for the Key ringneck snake and 5,972 acres of critical habitat for the Rim Rock crowned snake. The pine dockland habitat in which these snakes live has been reduced by 98 percent. The Key ringneck was identified as needing protection in 1982.
