4 <br />and Sy,^~phoricar;>os oreophilus, respectively. Other common names • <br />and scientific names used in this report can be cross matcYied in <br />Tables 1 through 3. <br />IJhen purchasing seed or seedlings it is important to 4:now the <br />plant species; however, this information may not be accurate. A.s <br />an example, we intended to use mountain brome which is Bro,.TUS car~- <br />inatus (Plummer et al., 1968) in all of the herbaceous seed mixes. <br />However, the seed purchased as mountain brome was in reality smooth <br />brome (Brorrus Lrrermis), Thus, all of our "native" mixes now include <br />- smooth brome (an introduced species) instead of mountain brome. <br />On the revegetation test plot, lambsquarter and a mustard were <br />abundant in 1976. In 1977, lambsquarter was the only common weedy <br />annual. In 1978, lambsquarter, mustard, and chickweed were the corri- <br />mon weedy annuals, but their abundance was limited. The weedy <br />annuals are not controlled on most of the plots in the study as <br />they will be common on reclaimed areas during establishment of - <br />desired perennials. Thus, competition between volunteer species and <br />seeded shrubs and herbaceous species may be a problem. However, it <br />is felt that this competition will be minimal after the first few <br />growing seasons as the cool-season perennials will leave little soil <br />moisture for the annuals. The volunteer species may be useful in <br />providing shade for seedlings and aiding in the accumulation of snow <br />by acting as a snowfence, Cover data was collected on volunteer <br />species in 1976, 1977, and 1978. This data along with data in future <br />years will lend insight into the ecology of these volunteer species. <br />The volunteer species were pulled on replication I of the <br />individual species seedings because one of the purposes of the study <br />was to serve as an orientation to the individual species. These ' <br />seedings could not serve this function if the seeded species were <br />obscurred by volunteer species. Also, the elimination of the volun- <br />teer species on the one replication will act as a control in deter- <br />mining the competitive importance of the volunteer species in <br />replications II and II[. <br /> <br />
