Criteria

Data/Comments

Environmental

 

(2) 100% exclusion of National Park Service and Fish and Wildlife Service managed lands.

USGS Federal and Indian Lands shapefile, Jan. 2005.

(3) 100% exclusion of federal lands designated as park, wilderness, wilderness study area, national monument, national battlefield, recreation area, national conservation area, wildlife refuge, wildlife area, wild and scenic river, or inventoried roadless area.

USGS Federal and Indian Lands shapefile, Jan. 2005.

(4) 100% exclusion of state and private lands equivalent to criteria 2 and 3, where GIS data are available.

State/GAP land stewardship data management status 1, from Conservation Biology Institute Protected Lands database, 2004.

(8) 50% exclusion of remaining USDA Forest Service (FS) lands (incl. National Grasslands).

USGS Federal and Indian Lands shapefile, Jan. 2005.

(9) 50% exclusion of remaining Dept. of Defense lands.

USGS Federal and Indian Lands shapefile, Jan. 2005.

(10) 50% exclusion of state forest land, where GIS data is available.

State/GAP land stewardship data management status 2, from Conservation Biology Institute Protected Lands database, 2004.

Land Use

 

(5) 100% exclusion of airfields, urban, wetland, and water areas.

USGS North America Land Use Land Cover (LULC), version 2.0, 1993; ESRI airports and airfields (2003).

(11) 50% exclusion of non-ridgecrest forest.c

Ridgecrest areas defined using a terrain definition script, overlaid with USGS LULC data screened for the forest categories.

Other

 

(1) Exclude areas of slope >20%. D

Derived from elevation data used in the wind resource model.

(6) 100% exclude 3 km surrounding criteria 2-5 (except water).

Merged datasets and buffer 3 km.

(7) Exclude resource areas that do not meet a density of 5 km2 of class 3 or better resource within the surrounding 100 km2 area.

Focalsum function of class 3+ areas (not applied to 1987 PNL resource data).

aStandard Version, last revised Jan. 2004.

bNumbered in the order they are applied.

c50% exclusions are not cumulative. If an area is non-ridgecrest forest on FS land, it is just excluded at the 50% level one time.
