Acreages within Risk of Mortality classes and Fire Condition Classes 1,2, & 3 stratified by Inventoried Roadless Area Category
Alaska and Puerto Rico are not included in this table because Fire Condition Class data were not available for those states.
All acreage figures are rounded to the nearest 1,000.

Definitions of Categories of Inventoried Roadless Areas
1B	Inventoried roadless area where road construction or reconstruction is not allowed
1B-1	Inventoried roadless area where road construction or reconstruction is not allowed, and the forest plan recommends as wilderness
1C	Inventoried roadless area where road construction or reconstruction is allowed
Definitions of Fire Condition Classes
1	Forested areas with an historically short fire return interval usually have frequent fires of low intensity
2	One or more fire return intervals have been missed, possibly resulting in increased fire sizes and intensities and decreased landscape mosaics and diversity
3	Multiple fire return intervals have been missed resulting in dramatic departure from historical conditions
