Steller Sea Lions

Steller sea lions (Eumetopias jubatus) are comprised of two populations: the western Distinct Population Segment (DPS) that occurs primarily west of Cape Suckling (144° W. Longitude) and the eastern DPS that occurs primarily east of Cape Suckling.  The eastern DPS was previously listed as a threatened species under the Endangered Species Act but has since recovered to the point that it is no longer considered threatened.  The western DPS has been listed as an endangered species since 1997.  That population is gradually increasing, although its numbers continue to decline sharply in the western and central Aleutian Islands for unknown reasons.  A Recovery Plan guides actions to recover the western DPS and a Post-Delisting Monitoring Plan guides monitoring for the eastern DPS to ensure that it continues to thrive.
