Releasing Wildlife

February 9, 2023

Question: Someone posted on Facebook that they were seeking a kingsnake to breed and release into the wild for rattlesnake control. Wouldn’t that be illegal? Should I report the post to CDFW?

Answer: Yes, this would be illegal. Written authorization from the California Department of Fish and Wildlife (CDFW) is required to release animals into the wild. CDFW would not approve this release for two general reasons: (1) The risk of spreading pathogens and parasites and (2) The risk of introducing new genotypes into the environment which could impact the species or ecosystem.

California kingsnakes are ubiquitous and habitat generalists. If a property doesn’t already have California kingsnakes, then it’s probably not suitable habitat. It wouldn’t be a healthy environment for the snakes, and they probably wouldn’t persist for long.

You can report release of captive wildlife through CalTIP, which stands for Californians Turn in Poachers and Polluters. Reports can be submitted anonymously. We genuinely appreciate your help in protecting against those who illegally harm the state’s natural resources!
