The dataset was originally issued in 2007 by the USDA Forest
Service Washington Office-Ecosystem Management Coordination staff. The Forest
Carbon Plan ecoregions generally follow subsection boundaries with a few
exceptions. In the FCAT Version subsections 341Fa,341Fb341Fc, 341Ff, 341Fe (Eastside) were
coded to the desert. Also, while most of subsection
M261B went to the Klamath Province, subsection M261Bb went to the North
Coast.The original data was compiled at 1:500,000 to 1:1,000,000
scales in participation with Federal and State agencies and nongovernmental
partners. The polygon descriptions are presented for the delineated 190 section
ecological units. Brief descriptions of the section map units provide an
abstract primarily of the climate, physiographic, and geologic substrate that
combine to form ecosystems with distinctive vegetation and other unique
ecological characteristics. More information of this data set can be found at
the FSGeoData Clearinghouse (http://fsgeodata.fs.fed.us/other_resources/ecosubregions.html).For more information, contact [email protected]
