EXHIBIT J ( Cont'd) <br /> <br />dominated generally by Sporobolus aeroides (Alkali Sacaton) <br />with Bromus sp. and Agropyron elongatum being subdominants. As <br />the time since disturbance increases, the Bromus and Agropyron <br />become much less apparent and the Sporobolus and Distichlis <br />become strongly dominant. <br />This pattern is also aided strongly by the degree of salt <br />and/or alkali in the soil. Highly alkaline and' saline areas <br />develop dense turfs of Desert Saltgrass, and this often <br />blends into the more upland portions of the Typha - Phragmites - <br />Distichlis wetland. <br />Atriplex canescens becomes common in local areas where <br />saline/alkaline conditions are obvious and disturbance has not <br />occurred for a very long time. It is heavily browsed and <br />therefore in poor condition. It seems to be strongly asso- <br />ciated with Desert Saltgrass. <br />Cover in this group is quite variable as would be <br />expected in a strongly successional community. At its <br />lowest, it exhibits about 25 percent cover. Where saline soils <br />are strongly influential and Saltgrass dominant, cover ranges <br />from 80 percent to 100 percent. <br />The group occurs on both the Wann sandy loam and on the <br />Halaquepts soils. The most saline/alkaline conditions are <br />found on the Halaquepts soils, but local patches of saline/ <br />alkaline soil can also be found in the Wann sandy loam. <br />C. Agropyron - Distichlis group - This group is a <br />fascinating and very important vegetation on the site. More <br />than any other, it indicates what can be done in revegetating <br />-42- <br />
