Graph of the Day: Abundance of Steller Sea Lions at Año Nuevo Island, 1990-2004

The decline of the central California breeding population cannot be attributed solely to any single threat listed below, but instead is the result of a combination of multiple threats. In some cases, exposure to one threat may make the animals more susceptible to the others (e.g., high level of contaminants may make an animal more susceptible to disease). The relative importance of many of these threats is not known.
