Steller Sea Lion Haulout Counts in British Columbia
The Steller sea lion (Eumetopias jubatus) is the largest of all sea lions and enjoys a lifespan of up to thirty years. In Canada, the Steller can be spotted along the rocky coast of British Columbia. These highly mobile marine mammals typically travel alone or in small groups, but they congregate in large numbers at traditional rookeries and haul-outs during the mating and pupping season. The population was severely depleted in Canada but following its protection in 1970, the size of the adult population has more than doubled.
The survey targeted Steller sea lions and sites were chosen based on knowledge of historically occupied rookeries and haul-out sites with nearby areas monitored for potential shifts in distribution. This dataset contains counts that have been collected from sightings of individuals in the 2016/2017 survey season.

- Supplemental Information
- Counts of pups and non-pups (adults or juveniles) in summer and fall or counts of non-pups in winter (pups no longer distinguishable from older age classes) were obtained from top-down digital photographs of sea lions on terrestrial haul-outs (rocks, reefs, sandbars, or infrastructure such as docks, etc) acquired during aerial surveys in 2016-2017. Surveys were conducted via Cessna 180 light aircraft at altitudes of ~ 180 m (600 ft) and speeds of ~ 200 km per hour (125 miles per hour).
