Produced as a framework for organizing and interpreting environmental data for inventory, monitoring, and research efforts. The descriptions of the 20 ecoregions of Alaska contained in this guide were derived by synthesizing information on the geographic distribution of environmental factors such as climate, terrain, soils, and vegetation. The specific procedures and materials used to delineate the ecoregion boundaries are documented, and the environmental characteristics in each ecoregion are described. Accompanied by a full-color oversize map of the ecoregions, their boundaries, and transitional areas. 42 full-color photos.
