Maps are based on records compiled for the first edition of Amphibians and Reptiles Native to Minnesota and several other sources including the James Ford Bell Museum (through February 2012), the Science Museum of Minnesota (through February 2009), the Minnesota County Biological Survey (through 2011), DNR Greenslip records, as well as other reports from herpetologists and the general public.

Previous county records lacking details to identify a subunit were not included in these maps.

Names are primarily based on Crother, B. I. (ed.). 2012. Scientific and Standard English Names of Amphibians and Reptiles of North America North of Mexico, with Comments Regarding Confidence in Our Understanding, Seventh edition. SSAR Herpetological Circular No. 39. 98 p.
