I Sample size adequacy was. calculated after the first five plots. Sampling continued until the <br />indicated sample size was reached. Sample size adequacy was achieved on the dryland <br />reference area with 31 plots (Table 1). On the irrigated pasture reference area, 17 plots <br />were required for adequary. <br />I Following completion of the field work, all production samples were air-dried. The samples <br />were then reweighed. The results of the reweighing were used to estimate mean herbaceous <br />production for each proposed reference area. <br />SPECIES COMPOSITION <br />The composition of plant species in each area was evaluated using the same data acquired <br />from the vegetative cover transects. The analysis involved calculating a relative cover value <br />for each species. The equation used in this analysis was: <br />Percent Relative Cover of Species X = r % Cover of Species X 1 ~1~~ <br />l % Total Vegctative Cover J <br />
