WIC will get bond release on portions of NH1. If the two consecutive studies are not favorable, <br />then any further NH1 vegetation studies will use the Airport Dryland Reference area . <br />As far as NH2 dryland vegetation studies are concerned, only the Airport Dryland Reference area <br />will be used. <br />Total vegetation cover for the 1999 Dryland Reference area (first hit) for the type averaged 24 <br />percent, with bare ground at 51 percent, litter at 21.6 percent, and rock fragments at 3.4 percent <br />(Table 2.04.10-30). Lichen and moss accounted for 0.1 percent of the mean cover. The perennial <br />grass component dominated with 23.2 percent cover and the annual grass component at 0.2 <br />percent cover. Shrubs had 0.6 percent cover. Consistent with the type designation, crested <br />wheatgrass (Agropyron Cristatum) had the highest perennial species cover at 22.8 percent (96 <br />percent frequency). The remaining species generally contributed less than one half percent cover <br />to the mean total vegetative cover. <br />Herbaceous production totaled 50.03 g/m2 or 447 pounds/acre with shrubs and 47.77 g/m2 or 436 <br />pounds/acre without shrubs (Table 2.04.10-31). The perennial grass component contributed the <br />• highest value at 47.5 g/m (424 pounds/acre) followed by perennial shrubs at 1.3 g/m' (11.2 <br />pounds/acre). The contribution of annual grasses and perennial (orbs was (1.1 and 0.2 g/mZ, <br />respectively). Actual contribution to annual production is most likely higher. In order to sample the <br />perennial species at the peak of their production, many of the earlier maturing annual species <br />were senescent or were already gone from the stand. <br />• (REVISED 8/15/00) 2.04.10 - 77 <br />
