Herptile Regulations

Blanding's Turtle

All native herptiles (herps) are considered protected and have some level of protection. An overview of state regulations related to amphibians and reptiles can be found in Wisconsin's Amphibian and Reptile Regulations.

For any planned land-disturbing activities, an Endangered Resources Review should be conducted before beginning the project to ensure that there will not be any impacts on rare species and that planned activities are in compliance with Wisconsin’s Endangered Species Law (s. 29.604 Wis. Stats.), as well as other laws about rare species.
