These forest land maps have been constructed based on data "that indicate the species forming a plurality of live-tree stocking" in their natural range. The maps delineate exactly where each timber cover type most commonly occurs. 1 of 19 Map Of All Major Forest Cover Types USFS Here is an index map of 20 major timber types in the United States as defined by the Society of American Foresters. Each forest type listed on the map is presented where it most frequently occurs within its native range. The tree type map is color-coded by each specific forest cover type and public lands are excluded. 2 of 19 Map Of Aspen-Birch Forest Type USFS This is a forest type map of Aspen-Birch.
