• As might be expected with a dense evergreen werstory, production in the understory (Table 6) <br />was very low with only 16.5 gm / sq.m. (197 Ib /acre). Perennlel sorb production of 9.9 gm <br />/sq. m. was greater than the 6.9 gm / sq.m. contributed by perennial graminoids. <br />Shrub density in the understory of this forested stand (Table 7) averaged 18.3 stems / 50 sq.m. <br />( 1481 stems /acre). The major portion of this total (14.4 stems / 50 sq.m.) was subalpine <br />fir saplings. The scattering of actual shrubs comprisetl only 3.9 stems / 50 sq.m. (316 stems / <br />acre). Species contributing to this scant total were mountain maple, Saskatoon serviceberry, <br />mouMein lover, trumpet gooseberry, Woods rose, and mountain snowberry. <br />Tree density in the Conifer vegetation type (Table 8) averaged 1 1 1.E stems / 250 sq.m. (1807 <br />stems /acre). Neighi of the dominant subalpine fir trees was consistently 15 to 16m. In the <br />largest dbh class present (50 -60 cm ),saes were 90 to 100 years. A somewhat smaller 39 <br />cm dbh fir was 80 years old. In the abundant dbh range of 2010 25 cm, ages were about 60 <br />years, while in the range of 10 to 15 cm dbh, ages were 29 to 36 years. <br />• <br />3.1.3 MEADOW <br />Throughout the study area, this vegetation type varied from a wetland heavily dominated by <br />sedges to a moist valley bottom dominated by Kentucky bluegrass and rediop (Aorostis albe), as <br />well es locelly abundant weedi~ species such ar hound's tongue (Gynodlossum officinale), Canada <br />thistle (Cirsium arvense), and flodman thistle (Cirsium incenum). As mentioned above, cattle <br />Brazing and sediment pond construction had revulted in extensive damage to this vegetation type <br />in the study area, necPSSiteting location of samples intended to represent this type in a protected <br />portion of the type inside the existing Seneca I I Mine permit areo (Figure 5). In this porticulor <br />location, the meadow was dominated by sedges. Cover was primarily accounted for by perennial <br />graminoids which comprised 77.4 cover out of a total vegetation cover of 80.4 (Table 9). <br />The most plentiful perennial graminoids were Nebraska sedge (Carex nebrascensis, 38.6 ~ <br />cover) end beaked sedge (Cerex utriculate, 34.4 cover). Kentucky bluegrass and fowl <br />bluegrass were the only other graminoids to make up es much es 1 ~ or more cover. Cover by <br />perennial forks was a scant 2.8~, the only major contributions to which were made by Canada <br />. thistle end cornlily (Veratrum tenuipetalum). Only on a few high spots in the meadow were e <br />taw trumpet gooseberry and 8ebb willow (5elix cf. bebbiana) shrubs found. <br />-12- <br />
