Ecological Drainage Units (EDUs) group watersheds that share a common zoogeographic history, physiographic and climatic characteristics, and therefore likely have a distinct set of freshwater assemblages and habitats. EDUs are hypothesized to account for the variability within fish zoogeographic sub-regions due to finer-scale drainage basin boundaries and physiography. EDUs are delineated as groups of 8-digit US Geological Survey Hydrologic Unit watersheds. EDUS were qualitatively defined by the TNC Freshwater Initiative using primarily USFS Fish Zoogeographic Subregions, USFS Ecoregions and Subsections, and major drainage divisions.
EAU BC is a hierarchical classification of BC's freshwater ecosystems. It is a spatially explicit classification designed to aid in the management and conservation of BC freshwater ecosystems and their associated biodiversity. EAU BC quantifies the interplay between freshwater species distribution and their ecosystem physical habitat, and environmental processes. It defines what is currently known about freshwater ecosystems and their abundance and distribution across the Province. It is packaged as a database and accompanying geographic information system (GIS) that enables the classification and its underlying data to be queried and viewed at multiple spatial scales. Available EAUBC GIS data include EAUBC Freshwater...
This table contains information on the Ecological Drainage Units for streams and catchments in the Upper Colorado Basin. This table can be linked or joined via the "COMID" field in the National Hydrography Dataset Plus Version 1 (NHDPlusV1) data.
