Globally, Northern or Steller Sea Lions are found in the "coastal waters of the North Pacific from California and northern Honshu, Japan, and Korea, north to the Bering Strait" (BC Species and Ecosystem Explorer 2009). They reside year-round and breed in British Columbia (DFO 2008), where they are found along the entire coast, usually within 45 km of shore (Cannings et al. 1999). Breeding males are territorial, and pup mortality is about 10% (BC Species and Ecosystem Explorer 2009). According to DFO (2008), from 1912-68, Steller sea lions in B.C. "were subject to predator control programs and commercial harvests. A total of 55,000 sea lions were killed during 1912-68, and by the 1970s breeding populations had been reduced to roughly 25-33% of the peak historic levels thought to have been present in the early 1900s".
In 2003, COSEWIC (2003) listed the status of this species as Special Concern, stating that it "..met criterion for Threatened, D2, but designated Special Concern because the population is increasing and there is a possible rescue effect." In a 2008 status assessment update conducted by the Department of Fisheries and Oceans Canada (DFO 2008), it was found that “the abundance of Steller sea lions in B.C. has increased at an overall rate of 3.5% per year since the early 1970s”. DFO (2008) also indicates that “during the most recent survey in 2006, a total of 19,818 sea lions were counted in B.C. This included 4,118 pups and 15,700 non-pups (7,171 on rookeries and 8529 on non-breeding haulout sites)". COSEWIC status presently remains the same. The species is currently blue-listed in British Columbia (BC Species and Ecosystem Explorer 2009).
