FRO Resources <br />daisy, knotweed, aster, stickseed and curly cup gumweed (Figure 4, Table <br />• 6). Mean herbaceous cover in this stand is approximately 3%. <br />The shrub layer of the Juniper Woodland type is also poorly developed. <br />Total shrub cover in the affected and reference sites are 4% and 18%, <br />respectively. The dominant shrub is little rabbitbrush (Chrvsothamrus <br />viscidiflorus) with a cover value of 2%. Big rabbitbrush is the second <br />most important shrub in this type with a cover value of 1%. Sagebrush has <br />a cover value of 1%. Other shrubs that occur are winterfat (Ceratoides <br />lanata), mountain mahogany (Cercocarpg_s montags) and prickly pear <br />(Wuntia pnlyacantha) (Figure 4, Table 6). <br />Tree density in the affected stand sampled is 831 individuals per hectare <br />(Table 8). Mean basal cover for Utah juniper is 0.07m2 in this stand. <br />Primary herbaceous productivity in the juniper woodlands is second lowest <br />of all affected vegetation types sampled. Total mean weight in the <br />affected site sampled is 8.7 g/m2. Cheatgrass accounts for the largest <br />ispart of the primary productivity in the juniper woodland type at 3.7 <br />g/m2. Other species that contribute substantially to primary <br />productivity in this stands include fleabane daisy, baby blue eyes and <br />curly cup gumweed. Grasses account for low levels of biomass. Westerr <br />wheatgrass averages 0.1 g/m2. Squirreltail grass accounts for 0.1 <br />g/m2 (Figure 5, Table 9). <br />E <br />The juniper woodlands are a topo-edaphic climax vegetation type in the <br />Intermountain Region. These woodlands are typically self-perpetuating <br />stands with orderly replacement of dead and diseased trees. The stands <br />sampled are relatively even -aged, but saplings of both Utah and Rocky <br />Mountain juniper do occur, even if infrequently. <br />The predominant use of the mine permit area is as sheep winter range. The <br />juniper woodlands are principally used as cover by sheep during winter <br />II.F-26 <br />
