This report presents a summary of the most recent inventory information for Idaho's forest lands. The report includes de- scriptive highlights and tables of area, number of trees, biomass, volume, growth, mortality, and removals. Most of the tables are organized by forest type, species, diameter class, or owner group. The report also describes inventory design, inventory terminology, and data reliability. Results show that Idaho's forest land totals 21.4 million acres. Nearly 76 percent (16.2 mil- lion acres) of this forest land is administered by the USDA Forest Service. Douglas-fir forests cover almost 6.3 million acres or roughly 29 percent of Idaho's forested lands, making it the most abundant forest type in the State. The lodgepole pine type is the second-most common type comprising 11.5 percent of Idaho's forest land. In terms of number of individual trees, subalpine fir is the single most abundant tree species in Idaho. Net annual growth of all live trees 5.0 inches diameter and greater on Idaho forest land totaled 376.2 million cubic feet. Average annual mortality totaled nearly 814.6 million cubic feet.
