Reptiles & Amphibians
Rare Species Guide User Survey
The Rare Species Guide is a dynamic, interactive resource for information on Minnesota's endangered, threatened and special concern species. You can make the Rare Species Guide even better by taking this short survey.
The Minnesota Biological Survey (MBS) conducts field surveys for amphibians and reptiles from April through October. Techniques vary depending on the target species, habitat, and time of year. Captured herpetofauna are weighed, measured, sexed, aged, and photographed prior to release. A variety of survey techniques are used.
