Oka,= <br /> ONION:_ inasnounzainioi�, <br /> 8 <br /> the extreme difficulty in counting individuals of certain species of shrubs <br /> typical in the mountain shrub type, such as snowberry, oak, rose, and <br /> serviceberry. In addition, this vegetation type itself is quite variable. Also, <br /> sample adequacy for production was not achieved for this type. Fifty plots, <br /> the point at which the Division allows a sampling cutoff, were clipped. <br /> Vegetation cover and herbaceous production of the meadow reference area <br /> are statistically equivalent to cover and production of the entire inventoried <br /> meadow area (see Table 29). Species composition, as reflected by cover <br /> data, differs somewhat from the meadow type as a whole. The reference <br /> area has more Kentucky bluegrass and forb cover and less timothy relative <br /> to the meadow area. It appears that the reference area has had somewhat <br /> greater utilization by livestock in the past than much of the rest of the <br /> area, and this utilization may possibly account for the reduced occurrence <br /> of timothy. <br /> Rock Tunnel Area. This area consists of a single vegetation type comprised <br /> of a dominant aspen overstory. The area is 11 acres and the vegetation is <br /> fairly uniform throughout. Vegetation cover, over 98 percent, is high. The <br /> dominant grass species is blue wildrye, with bearded wheatgrass, purple <br /> redgrass, mountain brome, and Kentucky bluegrass also comprising <br /> significant portions of the total grass cover. Grasses contribute about 42 <br /> percent of the total vegetation cover. Forbs contribute nearly 58 percent of <br /> the total vegetation cover. Dominant forbs include white peavine, anise <br /> sweetroot, wild geranium, and tuber starwort. <br /> Production in this area is 101 grams per square meter (oven-dry). Woody <br /> plant density averages 8 plants in a 15 meter by 5 meter transect. The two <br /> most abundant woody species are aspen and western snowberry. <br />
