Willamette Valley Synthesis Conservation Opportunity Areas (version 2.0)

Jul 2, 2014
The Nature Conservancy has worked with government agencies and non-profit partners to produce this synthesis of the major Willamette Basin conservation planning efforts. The primary goals of the Synthesis Project are to delineate priority terrestrial and freshwater sites where investment in conservation or restoration would best contribute to (1) the health of historically significant and functional habitats, (2) the survival or recovery of imperiled plants and wildlife dependent on those habitats, (3) improved floodplain connectedness to benefit water quality for aquatic biodiversity and (4) overall watershed health.

This version represents additions to the COA network that were brought forward by partners during the 2012 update process. Additionally, many topology errors have been repaired, and boundaries have been modified slightly to better reflect current landuses.

Spatial Resolution:
The polygons in this dataset have typically been digitized at 1 : 40,000, and all reasonable efforts have been taken to ensure that the best remaining habitat, as well as good restoration sites, are incorporated into this product. However, site boundaries should be considered approximations, and site surveys should be performed by qualified individuals before any conservation activities are performed.
