* These GIS overlays were prepared from coverages compiled at various scales and resolutions. To account for the differences in scales and resolutions, a percent-area by attribute was calculated for each characteristic overlay layer. The acres in each roadless category/characteristic attribute were calculated by multiplying percent-area and total acreages from the Inventoried Roadless Area coverage. Derived acres have been rounded to the nearest 1,000 acres.

All acreage figures are rounded to the nearest 1,000.
