This checklist covers the Western Salish Sea Region. The Boundary starts from Becher Bay in East Sooke Park and runs up the west coast including Jordan River, Port Renfrew, the West Coast Trail to the village of Bamfield with it extending as far west as the Canada - US Border. The boundary also extends north of Bamfield to include the Broken Islands and offshore to include Barkley Canyon. The boundary follows Loudon Channel east around the Broken Island Group then up Imperial Eagle Channel and Alberni Inlet to Coleman Creek. From Coleman Creek the boundary heads in a southeast direction following the mountain tops [Townicut Mt., Mt. Modeste, Mt. Todd, Survey Mt. To Empress Mt.] that make up the Juan de Fuca Drainage Basin. From here the boundary extends down due south including Sooke Potholes Provincial Park and uses the municipal boundary between Sooke and Metchosin as the checklist boundary following this line down to Becher Bay with it extending as far out as the US border.
