acre. The latter value is 86.7 ~ of the success standard. <br />' Thus, it may be statistically within the success limits set <br />for the community. Perennial production in the west area <br />' exceeds the standard (1793 pounds per acre), while the east <br />area falls well short (1268 pounds per acre) and more closely <br />approximates the grassland slope community production. <br />Woody stem density: (Table 6; summary in Table 11). <br />The woody stem density of the riparian area is much <br />t higher than for the grassland community. Average stem density <br />for the whole community was 1053 stems (or stem clumps) per <br />' acre. The west area had double the stem density that the east <br />area had. <br />Species diversity: (Table 8; summary in Table 12). <br />Twenty-six species were sampled over the 10 multiple hit <br />' riparian area transects. All but one of these species were <br />encountered in the west area (6 transects). However, only <br />' eleven species were sampled in the four east area transects. <br />' Five grass species contribute greater than 5 % relative <br />' cover, four of which are cool season grasses. Two are bunch <br />grasses (Elymus trachycaulus, Elytrigia intermedia) and two <br />' are sod formers (Poa pratensis, Pascopyrum smithii). The <br />community therefore lacks one cool season bunch grass <br />contributing greater than 5 ~ relative cover. The community <br />15 <br />
