Species of Greatest Conservation Need

The Idaho State Wildlife Action Plan provides a framework for conserving Species of Greatest Conservation Need and the habitats upon which they depend. It is the state’s guiding document for managing and conserving at-risk species. An integrated approach to implementing this strategy across all Fish and Game programs will reduce potential listings under the Endangered Species Act.

Update (9/28/2016): The Idaho State Wildlife Action Plan (SWAP) has been submitted to the U. S. Fish and Wildlife Service for review. This is a list of species included in the 2016 revision.
