<br />1 Habitat Suitability is derived from land cover types. Land cover types are a composite of GAP vegetation data, JBLM YTC vegetation data,
<br />and POWER Engineers Inc. (POWER) field survey vegetation data. Suitable habitat includes sagebrush/perennial grassland. Marginal habitat
<br />includes sagebrush/annual grassland, riparian, intermittent stream, and bitterbrush/perennial grassland. Unsuitable habitat includes forb,
<br />perennial grassland, rabbitbrush/annual grassland, annual grassland and noxious weeds, basalt cliffs/rock, trees, and other (includes
<br />agriculture, developed/residential areas and open water).
<br />2 Total within analysis area is less than the sum of all route segment analysis areas due to overlapping buffers
<br />* o = overhead design option; u = underground design option.
