This file includes the spatial boundaries for the Pacific Great Blue Heron Potential Area of Occupancy for its entire Canadian range. The Potential Area of Occupancy is a simple model that highlights the heron's preferred forest habitat at a high level. Potential Area of Occupancy is defined as terrestrial areas within the Coastal Douglas Fir and Coastal Western Hemlock Biogeoclimatic zones that are less than 10 km from a potential foraging area and west of the Cascades mountain range. Potential foraging areas are defined as the entire coastline and major river systems less than 1000 m in elevation. Refer to the "Management Plan for the Great Blue Heron fannini subspecies (Ardea herodias fannini) in Canada" on the SARA Regristry for more information.
