2014 Phase 11 BRB -2b <br />(Photographs 1 through 30) <br />COVER <br />(Table A -1) <br />The dominant lifeforms in the BRB -2b in 2014 were native perennial cool season grasses and introduced <br />perennial (orbs with 18.7 and 10.9 percent all -hit vegetation cover respectively. Introduced perennial forb <br />cover was composed mostly of alfalfa (Medicago sativa) and native perennial cool season grass cover <br />was predominantly composed of western wheatgrass (Pascopyrum smithii). Native perennial forb cover <br />comprised 5% of total vegetation cover and included 29 species, the most abundant of which were <br />western yarrow (Achillea millefolium ssp. lanulosa), showy goldeneye (Heliomeris multiflora), Rocky <br />Mountain penstemon ( Penstemon strictus), and American vetch (Vicia americana). Also observed in the <br />area were the noxious weeds bull thistle (Cirsium vulgare), hound's tongue (Cynoglossum officinale), and <br />Canada thistle (Cirsium arvense). <br />Total average vegetation cover for first -hits was 48.2 percent. Allowable all -hit herbaceous cover was <br />40.1 percent (Table F -1). Cover by standing dead, litter, bare soil and rock averaged 1.1, 24.5, 24.0 and <br />2.2 percent, respectively (first hits). Average species density was 29.1 species per 100 sq. m. <br />2014 Aspen Reference Extended Area <br />(Photographs 31 through 45) <br />COVER <br />(Table A -2) <br />Native perennial forbs were the predominant lifeform observed in the Aspen Reference Area, contributing <br />64.7 percent all -hit vegetation cover. The largest contributors to this total were nettleleaf gianthyssop <br />(Agastache urticifolia), leafybract aster (Aster foliaceous), showy daisy (Erigeron speciosus), northern <br />bedstraw (Galium septentrionale), white - flowered peavine (Lathyrus leucanthus), chiming bells (Mertensia <br />ciliata), western aniseroot (Osmorhiza occidentalis), Fendler meadow rue (Thalictrum fendlen), and <br />American vetch. Native shrubs and trees also contributed heavily with 36.4 and 41.7 percent all -hit <br />vegetation cover respectively - Saskatoon serviceberry (Amelanchier alnifolia) contributed 7.5 percent, <br />mountain snowberry (Symphoricarpos rotundifolius) contributed 12.1 percent and aspen contributed 41.7 <br />percent all -hit vegetation cover. Native perennial cool season grasses also made a moderate contribution <br />12 <br />
