Ecoregions of Alaska and Neighboring Territory
Greg Nowacki or Page Spencer USFS or NPS. 2001. Ecoregions of Alaska and Neighboring Territory. Torre Jorgenson
Major ecosystems have been mapped and described for the State of Alaska and nearby areas. Ecoregion units are based on newly available datasets and field experience of ecologists, biologists, geologists and regional experts. Recently derived datasets for Alaska included climate parameters, vegetation, surficial geology and topography. Additional datasets incorporated in the mapping process were lithology, soils, permafrost, hydrography, fire regime and glaciation. Thirty two units are mapped using a combination of the approaches of Bailey (hierarchial), and Omernick (integrated). The ecoregions are grouped into two higher levels using a "tri-archy" based on climate parameters, vegetation response and disturbance processes. The ecoregions are described with text, photos and tables on the published map.
