• houndstongue (0.2 percent average total cover, 80% frequency) and Canada thistle (no
measurable cover, 40% frequency).
Total average vegetation cover, for first hits, was 33.6 percent. Total average vegetation cover,
for all hits, was 34.8 percent. Standing dead, litter, bare soil, and rock each had 0.2, 6.4, 59.2,
and 0.6 percent cover, respectively. Average species density was 27.4 species per 100 sq.m.

Cover
(Table 8)
Native perennial forbs were most abundant, contributing 73.0 percent toward the total 152.4
percent vegetation cover (all hits). Within this group, western aniseroot (Osmorhiza occidentalis),
mountain bluebells (Mertensia ciliata), and serrate groundsel (Senecio serra) were most
extensive, having 19.3, 12.0, and 11.1 percent cover (all hits), respectively. Native shrubs
• composed 38.4 percent all-hit cover. Saskatoon serviceberry (Amelanchier alnifolia), mountain
snowberry, and chokecherry were the dominant native shrubs with 18.1, 14.4, and 4.5, percent
all-hit cover, respectively. Native perennial cool season grasses, provided 10.5 percent cover, of
which most was blue wildrye (Elymus glaucus), with 7.7 percent all hit cover. Quaking aspen
(Populus tremuloides) was an important component of the vegetation, contributing 28.8 percent
all-hit vegetation cover. In general, this area had high cover values because of the prevalence of
shrubs and trees. Because of the existence of tree, shrubs and herbaceous layers, all-hit cover
data summed to a total percent cover of greater than one hundred.
Total average vegetation cover, for first hits, was 92.9 percent. Total average vegetation cover,
for all hits, was 152.4 percent. Standing dead, litter, and bare soil, each had 0.5, 5.1, and 1.6
percent cover, respectively (first hits). Average species density was 28.6 species per 100 sq.m.
Production
(Table 9)
Total average production was 1477.5 Ibs per acre. Native perennial forbs contributed the majority
to production with 1247.3 Ibs per acre. Native perennial cool season grasses contributed an
average production of 198.1 Ibs per acre. Introduced annual and biennial forbs and introduced
perennial forbs were also present, each with less than 30 pounds per acre.
