• Production (Table 5)
Alfalfa was not present in the samples from this reclamation area. Herbaceous
production for all other species averaged 763.7 pounds per acre.
Woody Plant Density (Table 6)
Native shrubs averaged 202.4 stems per acre. Saskatoon serviceberry contributed more
than two-fifths of this total and chokecherry (Padus virginiana ssp. melanocarpa)
accounted for one-fourth. The balance was contributed by mountain snowberry,
Gambel's oak (Quercus gambeliQ, bitterbrush (Purshia tridentata) and prickly rose (Rosa
sayi).
Wadge Pasture Reclaimed Area
Woody Plant Density Data (Table 7)
Native shrubs averaged 335.9 stems per acre. Big sagebrush contributed three-fifths of
this total. Mountain snowberry contributed nearly two-fifths of this total and the
remaining balance was accounted for by Saskatoon servieeberry.
Mountain Brush Reference Area
(Photographs 9, 11-12)
Cover (Table 8)
Native shrubs were the dominant lifeform in this area and contributed 61.4 percent of
total vegetation cover. Mountain snowberry contributed more than one-third of this total.
• Both saskatoon serviceberry and Gambel's oak contributed more than one-fourth of this
lifeform's total. Chokecherry, Wood's rose (Rosa woodsiQ, silver sagebrush, and big
sagebrush made minor contributions. Native perennial cool season grasses contributed
16.5 percent of total vegetation cover. Agassiz bluegrass accounted for nearly half and
elk sedge (Carex geyen) averaged more than one-fourth of this lifeform's total. Nine
other species made minor contributions. Native perennial (orbs averaged 16.0 percent
of total vegetation cover. Horsemint (Monarda fistulosa var. menthifolia) contributed
more than one-third of this total. Nettle-leaf giant hyssop (Agastache urticifolia)
accounted for nearly one-fifth of this total. Seventeen other species accounted for the
balance. Introduced annual and biennial forbs averaged 3.4 percent of total vegetation
cover. Hound's tongue (Cynoglossum officinale) accounted for more than nine-tenths of
this total. The only other contributor was bull thistle. Bracken fern (Pteridium aquilinum
ssp. lanuginosum) accounted for 1.7 percent of total vegetation cover. Both native
annual/biennial forbs and introduced perennial forbs contributed 0.4 percent of total
vegetation cover. The two main native annuals were linearleaf collomia (Collomia
linearis) and Douglas knotweed (Polygonum douglasir), while the two main introduced
perennial forbs were Canada thistle (Breea arvensis) and dandelion (Taraxacum
officinale). Quaking aspen (Populus tremuloides), a native tree, contributed 0.2 percent
of total vegetation cover.
Total vegetation cover was 66.2 percent. Litter and bare soil were 24.2 and 9.6 percent
respectively. Species density was 34.3 species per 100 sq.m.
