Columbia River Estuary Ecosystem Classification - Concept and Application

Read more about Columbia River Estuary Ecosystem Classification - Concept and Application

This document describes the concept, organization, and application of a hierarchical ecosystem classification that integrates saline and tidal freshwater reaches of estuaries in order to characterize the ecosystems of large flood plain rivers that are strongly influenced by riverine and estuarine hydrology. We illustrate the classification by applying it to the Columbia River estuary (Oregon-Washington, USA
