This coverage contains ecological provinces for the United States portion of the Columbia River Basin. The base version of this coverage was obtained from Streamnet in 1999. This version is the result of three major revisions by the Northwest Habitat Institute in cooperation with the Northwest Power Planning Council and the Bonneville Power Administration. These ecological provinces align with the current version of the Columbia River Basin 6th Order HUCs coverage.
Purpose:
Created for the Northwest Power Planning Council's (NWPPC) Fish and Wildlife 2000 program.

Attribute_Accuracy_Report:
This data has been reviewed by the Northwest Power Planning Council, Bonneville Power Administration and the Northwest Habitat Institute. The accuracy of the attributes is generally considered good. The ecological provinces are mapped and attributed as defined by the Northwest Power Planning Council's Fish and Wildlife 2000 program.
Logical_Consistency_Report:
Ecological provinces delineations were detemined by staff of the Northwest Power Planning Council's Fish and Wildlife 2000 program and its affiliated organizations. These delineations were derived from and align with the current (version 3) Columbia River Basin 6th Order HUCs and Subbasins coverages.

Source_Contribution:
Version 2 of CRB Ecological Provinces was reviewed and edited by BPA. These edits were passed back to NHI as an ESRI Shapefile. NHI incorporated these edits back into the current coverage (Version 3) forcing the edited delineations to align with the Version 3 6th Order HUCs coverage where appropriate.
