Variable General Info
Upslope habitat ?Comment:"The upslope habitat model evaluates suitability of feeding and breeding habitat for approximately 100 species (Adamus et al. 2000, species-habitat relationships, internal report, US EPA, Corvallis, OR). A subset of species was chosen for the case study to emphasize protection and restoration of habitat for species not modeled by the other submodels. The model iterates over all cells in the landscape and scores each cell using a number of rules that involve LULC and physiographic characteristics of the cell and neighboring cells. Species groups with different biophysical requirements are treated differently. The landscape level score for a species group is an area weighted average. The target species included: Great Blue Heron, Wood Duck, Osprey, Belted Kingfisher, Killdeer, Little Brown Myotis, American Beaver, Mink, Northern River Otter, Pacific Water Shrew, Northwestern Salamander, Western Terrestrial Garter Snake, Roughskin Newt, Red-Legged Frog, Western Pond Turtle." |
