D1
Assessment rationale/justification
The population is small, and is limited by the availability of its principal prey, Chinook Salmon. It is also at risk from physical and acoustical disturbance, oil spills and contaminants. However, this population has been increasing slowly but steadily since monitoring began in 1975.; Cette population est petite et est limitée par la disponibilité de sa principale proie, le saumon chinook. Elle est également menacée par les perturbations physiques et acoustiques grandissantes, les déversements d'hydrocarbures et les contaminants. Toutefois, cette population augmente lentement, mais de façon constante, depuis le début de son suivi en 1975.
