HERBACEOUS PRODUCTION (TABLE 5)
Total herbaceous production averaged 2,334 pounds per acre.
• Mountain Brush Extended Reference Area
(Photographs 9 through 12)
COVER (TABLE 6)
Native shrubs comprised 70.1 percent of total vegetation cover in this reference area. Gambel's
oak accounted for nearly half and mountain snowberry averaged over one-quarter of this total.
Together, Saskatoon serviceberry, chokecherry and big sagebrush accounted for the balance.
Native perennial cool season grasses averaged 19.3 percent of total vegetation cover. Agassiz
bluegrass (Poa agassizensis) contributed nearly one-half of this total. Elk sedge (Carex geyen)
and needle and thread (Hesperostipa comata) were also abundant species in this lifeform. Native
perennial forbs contributed 5.6 percent of total vegetation cover. Native annual and biennial (orbs
accounted for 0.4 percent of total vegetation cover. Introduced annual grasses, introduced
annual and biennial forbs, introduced perennial forbs and introduced perennial cool season
grasses each accounted for one percent or less of total vegetation cover.
Total vegetation cover was 64.8 percent. Standing dead, litter, bare soil, and rock averaged 2.4,
21.0, 11.2, and 0.6 percent respectively. Total species density averaged 25.4 species per 100
• sq. m.
HERBACEOUS PRODUCTION (TABLE 7)
Total herbaceous production averaged 500.2 pounds per acre.
Sagebrush Extended Reference Area
(Photographs 13 through 16)
COVER (TABLE 8)
Native shrubs were dominant in this area and provided 44.0 percent of total vegetation cover. Big
sagebrush averaged more than one-half of this total. Mountain snowberry contributed two-fifths
of the total. Saskatoon serviceberry, Douglas rabbitbrush (Chrysothamnus viscidiflorus) and
Gambel's oak accounted for the balance. Native perennial cool season grasses accounted for
40.4 percent of total vegetation cover. Agassiz bluegrass comprised nearly one-half of this total.
Native perennial forbs contributed 10.4 percent of total vegetation cover. Together, timber
milkvetch (Astragalus miser var oblongifolius), chokecherry lupine (Lupinus prunophilus),
oneflower wood sunflower (Helianthella uniflora) and James starvvort (Pseudostellaria jamesiana)
accounted for more than one-half of the total. A total of 28 species of native perennial forbs were
encountered during sampling in this area. Introduced annual and biennial forbs accounted for 2.6
• percent of total vegetation cover. Introduced annual grasses accounted for 0.9 percent.
