Forest Resources of the United States, 2007. A Technical Document Supporting the Forest Service 2010 RPA Assessment.

摘要

Forest resource statistics from the 2000 Resources Planning Act (RPA) Assessment were updated to provide current information on the Nations forests. Resource tables present estimates of forest area, volume, mortality, growth, removals, and timber products output in various ways, such as by ownership, region, or State. Current resource data and trends are analyzed and placed within the context of changes since 1953. Additional analyses look at the resource from an ecological, health, and productivity perspective. A mini-atlas of map plates includes national displays of forest type, ownership, biomass, fragmentation, and other key spatial elements.
