Wisconsin's endangered and threatened species list

Some banner

The first list of Wisconsin endangered and threatened (E/T) species was developed in 1972 following enactment of Wisconsin's endangered species law. The list was created to restrict the taking, possession or marketing of species threatened with extinction from the state.

How and when is the E/T species list revised?

Since 1972, the list has been revised 11 times, most recently in January 2014. The DNR's Natural Heritage Conservation Program policy recommends that the E/T list should be reviewed at every five years or earlier, as needed, based on changes in species population condition. However, because changes in a species status can occur more frequently, these changes are reflected in the state's Natural Heritage Working List, which is dynamic and is updated as new information becomes available. Additionally, according to Wisconsin Law - Chapter NR 27.04 Wis. Adm. Code [exit DNR] - "Any 3 persons may petition the department to review the status of any listed or unlisted wild animal or wild plant."

E/T list revision 2014

In 2010, a comprehensive list review began that resulted in adding eight species [PDF] and removing 15 species [PDF] from the list. The changes became effective January 1, 2014. As a follow-up action, the department initiated a new administrative rule process (ER-30-13) and in 2015, Blanding's turtle was added to the protected wild animals list.
