Ecological Aquatic Units of British Columbia (EAU BC) is a hierarchical classification of BC’s freshwater ecosystems. EAU BC classifies freshwater systems at three spatial scales - Freshwater Ecoregions, Ecological Drainage Units, and River and Lake Ecosystems - based on measurable environmental features, processes and biological data. Freshwater Ecoregions are defined based on zoogeographic patterns in fish recolonization following the last glacial recession. Five Freshwater Ecoregions are identified in BC.
