Species of Greatest Conservation Need

The Idaho Comprehensive Wildlife Conservation Strategy 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, most of which are not hunted, trapped, or fished. 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.
