Ecosystem/Habitat Classification

Columbia River Estuarine Ecosystem Classification GIS Layers

The Columbia River Estuaryine Ecosystem Classification is comprised of a hierarchical group of 6 geospatial data sets which characterize the unique ecosystem of the lower Columbia River and estuary.  The framework was developed for applications in larger river systems characterized by very long reaches of tidal freshwater (nearly 200 km, in the case of the lower Columbia).
