Learn more about Amphibians and Reptiles in Minnesota.

MHS is committed to the study and conservation of Minnesota’s 50 species of amphibians and reptiles. We regularly fund grants in herpetological conservation and research conducted in Minnesota and beyond. MHS also conducts field surveys throughout the state.

MHS is also active in many aspects of herpetological education. We developed and implemented educator workshops to help prepare classroom teachers and naturalists to use reptiles and amphibians in the classroom by providing training and materials, beginning with four “Tips and Tools for Teaching About Reptiles and Amphibians” workshops in 2001. Find out more information about HandsOn events here.

    Journalist William Souder follows this story in his book, u201cA Plague of Frogs: The Horrifying True Storyu201d. Souder tells this tale better than anyone and his book is a great overview if youu2019re interested in Minnesotau2019s deformed frogs.
