Summary

Ecoregions denote areas of general similarity in ecosystems and in the type, quality, and quantity of environmental resources. They are designed to serve as a spatial framework for the research, assessment, management, and monitoring of ecosystems and ecosystem components. These general purpose regions are critical for structuring and implementing ecosystem management strategies across federal agencies, state agencies, and nongovernment organizations that are responsible for different types of resources within the same geographical areas. The approach used to compile this map is based on the premise that ecological regions can be identified through the analysis of patterns of biotic and abiotic phenomena, including geology, physiography, [...]

Purpose

The 16 EPA Level IV ecoregions that interesect the Columbia Plateau project area were lumped into 6 classes based on ecological similarity by Rex Crawford of the WA DNR NHP. These coarser classes were used to geographically stratify some land cover types in the ALI Marxan analysis of the region.
