Status of the California Sea Lion, Zalophus calif ornianus, in Canada

Abstract

The California sea lion (Zalophus californianus ) is seen in British Columbia during September-May, primarily off Vancouver Island. Only adult and subadult males are found here. The species was rare in British Columbia between the late 1800s and the 1960s, and was confined to southwestern Vancouver Island. In the 1970s, the range expanded into waters off southeastern Vancouver Island. Total numbers increased from about 500 animals in 1972 to 4,500 in 1984, with most of the increase taking place since 1980.
