As the state’s human population continues to grow, more fish and wildlife species have been put at risk by loss and fragmentation of critical habitat, disturbance and introduction of non-native species. The Washington Department of Fish and Wildlife oversees the listing and recovery of those species in danger of being lost in the state.
A printable PDF version of the list is also available.
