The Great Blue Heron Ardea herodias is an iconic species representing the natural heritage, interconnectedness and ecological richness of Puget Sound and the greater Salish Sea Puget Sound, Strait of Georgia and Strait of Juan de Fuca. This area constitutes the greatest concentration of Great Blue Herons on the West Coast and harbors some of the largest heronries in North America. As a predator and nearshore-associated species, heron populations are indicative of levels of environmental toxins, availability and connectivity of shoreline-upland habitat, and conditions of eelgrass and intertidal habitats.
