About this dataset
Ecological Drainage Units (EDU's) are nested within Freshwater Ecoregions and take into account zoogeographic, climatic, and physiographic patterns that define freshwater systems. Ecological Drainage Units represent distinct major drainage basins that contain unique assemblages of native B.C. freshwater fish. Thirty-six Ecological Drainage Units are identified in BC.
