Ecosystems of Northern Alaska (Jorgenson & Heiner 2003)

Map image, GIS data and publication pending - This map was funded by The Nature Conservancy to provide a seamless ecological context for analysis of the distribution of biodiversity in the Northern Alaska ecoregion. It covers all of Alaska north of the latitudinal treeline on the southern side of the Brooks Range. It includes of the Alaska North Slope and most of the Brooks Range. It is in raster tif format, with 30-m pixel resolution. The legend has 36 terrestrial ecosystem classes and 4 non-vegetated classes, nested within five landscape types: coastal, riverine, lowland, upland, and alpine.

The map classes were modeled using existing land cover maps covering portions of the project area, integrated and reclassified using ancillary information to partition ecological characteristics. Physical, biological and geographical information were incorporated to produce the ecosystem classification.
