Summary
[edit]
| Description |
English: "Unified Ecoregions of Alaska: 2001. This ecoregion map combines the Bailey and Omernik approach to ecoregion mapping in Alaska. The ecoregions were developed cooperatively by the U.S. Forest Service, National Park Service, U.S. Geological Survey, The Nature Conservancy, and personnel from many other agencies and private organizations."
Quoted from source (Metadata): The Ecoregion units are arranged in two higher levels along
gradients of climate, vegetation and disturbance processes.
Thirty two ecoregions fit into eight groups at Level 2, and
three regimes at Level 1 (Boreal, Maritime and Polar).
Please refer to the tri-archy found on the back of the
published map. Written descriptions are located in the
section of Overview Description, following the individual
ecoregional descriptions.
