• inermis ssp. oumoellianus), sun sedge (Cerex helioohila), end fowl bluegrass (Poe oalustris). <br />Tolal herbaceous production to the Aspen veaetetlon type (Table 2) was 88.6 gm/sq.m. (789 <br />lb/acre). Perennial fortis were the largest contributors (49.6 gm/sq.m.), closely followed by <br />perennial graminoids (36.3 gm/sq.m.). Kentucky bluegrass end bracken fern were the largest <br />individual species contributors. <br />Shrub density In the Aspen type (Table 3) averaged 42.6 stems/50 sq.m. (3448 stems /acre). <br />By far the greatest contributor to this density was mountain snowherry (23.1 stems / 50 <br />sq.m.). Other major contributors were Saskatoon serviceberry (9.5 stems / 50 sq.m.), Gembel <br />oak (2.8 stems / 50 sq.m.), end aspen saplings (2.4 stems / 50 sq.m. ). <br />Average tree density in the Aspen type (Table 9) of 12.5 / 250 sq.m. (202 stems /acre) is, of <br />course, misleading since many of the stands had most or all trees removed by beaver. Of the 15 <br />stands that bed any trams ai all, the average was 16.6 stems / 250 sq.m. (269 stems /acre). <br />The aspen in the camp tad stands where aspen were present averaged i i m in height. The largest <br />trees were typically in the diameter-et-breast-height (dbh) range of 20 io 25 cm, with ages of <br />50 io 65 years. In the abundant 10 to 15 cm dbh size class, egos were in the low 40's. <br />3.1.2 CONIFER <br />The Conifer vegetation type was confined to a single stand on a steep north-facing slope in the <br />northeast pert of the study area (Map 1 ,Figure 3). The stand is dominated by a single species, <br />subalpine fir (Abies lesiocerpa), which forms a very dense overstbry throughout much of the <br />stand (Figure 4). Cover by subalpine fir averaged 65.2`8 (Table 5), by far the bulk of the <br />73.2 total vegetation cover in the stand. Forb and graminoid development was greater in areas <br />where tree werstory was less dense (see Sample 1, Table 5), but overall perennial forb and <br />perennial graminoid cover averaged only 2.4~ each. Perennial forb species present in the scant <br />cover include a vegetative aster (Aster sp.), white-flowered peavine, spreading eniseroot, <br />fendler meadowrue, end violet. Oraminoids occasionally enwuntered included elk sedge ( r x <br />ri), blue wildrye, timothy (Phleum ratertse), end Kentucky bluegrass. <br />Shrubs managed only 2.0~ cover, comprised of Saskatoon serviceberry, Oregon grape, end <br />. mountain snowherry. Mosses and lichens were present in the amount of 0.8~ cover. <br />-9- <br />
