This report presents the results of an inventory of Utah's forest lands, completed in 1995. It is the first of its kind for the Interior West States in that it includes all forested lands, regardless of ownership or administrative status. It also includes information on a multitude of forest ecosystem attributes. Included in this report are tables and highlights of area, numbers of trees, biomass, volume, growth, mortality, successional stage, understory vegetation, removals, and net change. Much of the information is organized by forest type, species, diameter class, or owner. The report also explains inventory design and inventory terminology, and discusses data reliability. Roughly 29 percent of the area of Utah is forest land, and about 83 percent of the forest land is administered by government agencies. Only about 5 percent of the forest land in Utah is reserved from being utilized for wood products. The most common forest type is pinyon-juniper, composing 49 percent of the total forest land. The tree species estimated to have the highest percent of the total number of trees is Gambel oak, with 25 percent. The tree species estimated to compose the largest percent of biomass is Utah juniper, with 24 percent of the total biomass and 25 percent of the total cubic foot volume. The total volume of wood in live trees in Utah is estimated to be over 15.3 billion cubic feet. The area of timberland not reserved from harvesting is about 4.9 million acres, or 31 percent of the forest land. The net volume of growing stock on nonreserved timberland is over 7.4 billion cubic feet, with almost 78 percent of that on lands administered by the National Forest System.
