Steller Sea Lions Rebound Off Endangered List

Steller sea lions

A five year plan to shore up dwindling populations of eastern Steller sea lions, the threatened species that roams from Alaska to California, has succeeded. NOAA Fisheries announced last week it will be delisting the animal as a threatened species, having exceeded its goal for annual population growth by more than thirty percent.

As marine predators that forage on a variety of fish, squid, and other species, Steller sea lions are a vital component of North Pacific Ocean ecosystems. Their recovery is a testament to the value and success of the Endangered Species Act in ensuring the health of marine ecosystems for future generations.

First listed range-wide as threatened under the ESA in 1990 following severe population declines, the Steller sea lion population was later split into Distinct Population Segments of eastern and western in 1997, following an intensive period of research on genetic structure, population trends, movements, and other factors. The eastern DPS, which ranges from Cape Suckling, Alaska, south to the Channel Islands, California, retained its threatened listing while the western DPS was classified as endangered.
