A GIS dataset delineating Oregon Plan Core Areas as designated in the Original
Draft Oregon Plan dated August 6, 1996.
The purpose of the dataset is to illustrate and quantify the Core Areas.
1:100,000 scale hydrograpy was plotted and provided to staff involved in the Coastal Salmon Restoration Initiative (CSRI) (now known as The Oregon Plan for Salmon and Watersheds). Staff then delineated Core Areas by species using procedures described in the "Original Draft Plan" dated August 19, 1996. This document is available at http://rainbow.dfw.state.or.us/nrimp/default.aspx . The specific delineation procedures are discussed in SECTION VI-H. This information then added to the 1:100,000 hydrography as an item in the .aat. At a later date it was converted to an event table displayed via routed 1:100,000 streams.

Maps of Core Areas for salmon are not intended to cause economic penalties to
private landowners if salmon currently concentrate for spawning or rearing in
stream reaches on their property. The maps are not intended to endorse
relaxation of existing environmental protection rules in areas presently
outside of Core Areas. Such actions would serve to perpetuate existing
geographic patterns of salmon production within river basins and would inhibit
the restoration process.
The useful attributes in this coverage are the species codes in the .aat.
They are defined as follows: 1 - coho; 2 - fall chinook; 3 - spring chinook; 4
- winter steelhead; 5 - summer steelhead; 6 - chum.
Aside from the original delineation there have been no further updates nor
additions to the data.
