Minnesota law requires the DNR to maintain a list of species that are at risk of disappearing from the state. Listed species are placed into one of three categories: endangered, threatened and special concern. The list is based on scientific field studies, such as those conducted by the Minnesota Biological Survey.
Minnesota’s List of Endangered, Threatened and Special Concern Species was first established in 1984, and has recently been updated.
The Statement of Need and Reasonableness (SONAR) contains an overview and supporting evidence for the recent updates.
