with mountain snowber:y providing over half of this total. Chokecherry was the other <br />most abundant shrub, while serviceberry, basin big sagebrush, mountain big :;agebrush, • <br />and Douglas rabbitbrush each made similar contributions to the remainder of the total. <br />Soecies Density and Soecies Comoosition <br />Tables 1 through 13 show species density data from each cover sample; the;te data are <br />summarized in Table 39 and are graphically depicted in Figure 4. <br />Species composition, as reflected in cover data, is present in Tables 11 through 13. Table <br />40 summarizes the relative cover data from these tables by lifeform and provenance. <br />Figure 5 graphically depicts these same data. <br />Species and lifeform density data reflect both total species/lifeform richness and <br />equitability. The latter is incorporated by virtue of the fact that the occurrence of species <br />is tallied within fixed unit areas (100 m'), and thus frequency is addressed simultaneously <br />with species richness. The highest total species density of all reclaimed areas was <br />observed in the young reclaimed areas (1988 Wadge and 1988 Wolf Creek), where annual <br />and biennial weedy plants are abundant in early stages of secondary ;succession. Equally • <br />high species density was found in the 1983 Wolf Creek and 1986 W:sdge Fall areas. <br />Highest native species density of all, as well as highest total species density, was in the <br />Native Study Area (Table 391• Mountain Brush and Sagebrush References Areas (22.9 and <br />25.9 native species per 100 m') were actually approached in native species density by <br />several reclaimed areas, most closely by the 1983 Wolf Creek, 1986 Wadge Fall, and <br />1988 Wolf Creek areas (18.9, 16.3, and 16.2 native species per 100 m' respectively). <br />Total species density was greater than both the reference areas in the: 1983 \Nolf Creek, <br />1986 Wadge Fall, 1988 Wadge, and 1988 Wolf Creek areas; total species density <br />exceeded the Mountain Brush (but not the Sagebrush) Reference Aree: in the 1986 Wadge <br />Spring and 1986 Wolf Creek areas. Total species density in the Wadge Pasture (20.9 <br />species per 100 m') slightly exceeded the figure in the Wadge Pasture Comparison area <br />(19.4 species per 100 m'1; the comparison for native species density was very similar <br />(12.1 versus 11.9 species per 100 m', respectivelyl. <br />Annual and biennial forbs were, not unexpectedly, most diverse in the youngest <br />reclamation areas (1988 Wadge and 1988 Wolf Creekl; this was true for both introduced <br />and native annuals and biennials. The level of native annual and biennial forbs: present in • <br />10 <br />
