Total vegetation cover (first hit) for the type averaged 24 percent, with bare ground at 51 <br />• percent, litter at 21.6 percent, and rock fragments at 3.4 percent (Table 22-4). Lichen <br />and moss accounted for 0.1 percent of the mean cover. The perennial grass component <br />dominated with 23.2 percent cover and the annual grass component at 0.2 percent cover. <br />Shrubs had 0.6 percent cover. Consistent with the type designation, crested wheatgrass <br />(Agroovron Cristatum) had the highest perennial species cover at 22.8 percent (96 <br />percent frequency). The remaining species generally contributed less than one half <br />percent cover to the mean total vegetative cover. <br />Herbaceous production totaled 50.03 g/m2 or 447 pounds/acre with shrubs and 47.77 <br />g/m2 or 436 pounds/acre without shrubs (Table 2.04.10-31). The perennial grass <br />component contributed the highest value at 47.5 g/m (424 pounds/acre) followed by <br />perennial shrubs at 1.3 g/mZ (11.2 pounds/acre). The contribution of annual grasses and <br />perennial (orbs was (1.1 and 0.2 g/m2, respectively). Actual contribution to annual <br />production is most likely higher. In order to sample the perennial species at the peak of <br />their production, many of the earlier maturing annual species were senescent or were <br />already gone from the stand. <br />• The 1999 amendment to the approved the use of this reference area for all <br />reclamation of dryland pasture and rangeland in the New Horizon 2 Mine area. <br />It is proposed here that the same reference area be used for evaluating the success <br />of the reclaimed rangeland and dryland pasture of NH1. <br />.
