This number <br />was used as the number of degrees west of magnetic north. The <br />transect was then oriented in that direction. <br />Semi-shrubs were defined as species which are woody at the <br />base and are mostly herbaceous throughout the rest of the plant. <br />No annual forbs were encountered in the production samples. <br />The basis for sorting forbs was whether they were annuals or <br />perennials. The system is appropriate even if no annual forbs are <br />encountered. <br />Figure 1 appears as Plate 16 in the permit application. <br />Dry Grassland. The dry grassland type occurs on ridges where <br />soils tend to be thin and moisture conditions are less favorable <br />than those on slopes and bottomland areas. Mostly, these areas are <br />too dry to support substantial shrub development. <br />Big Sagebrush Shrubland. The big sagebrush shrubland type <br />occurs on side slopes and bottomland areas where moisture conditions <br />are somewhat more favorable than those on upland sites. The soils <br />range from moderately shallow on the side slopes to somewhat deeper <br />on the bottomlands. In winter, snow tends to accumulate on the <br />sagebrush sites to a greater degree than it does in the areas <br />covered by the dry grassland type. <br />F-6 <br />
