Borehole Sites <br />Many of the borehole sites for the D-seam area were inspected. 'T'hey are at various stages of <br />vegetation establishment. In general the revegetation is good and the sites are stable. A table <br />is attached providing remazks for each location. <br />Other Sites <br />B-vent Shaft and access road <br />This site was disturbed and seeded in 1998. 1999 was the first growing season for this site. <br />Seedling establishment was somewhat sporadic but showed good signs of growth form <br />diversity. Several species of fortis and shrubs did well on this site. Parts of this site aze <br />heavily infested by Cheatgrass. This is not surprising since the herbaceous vegetation on the <br />undisturbed site was dominated by this species. <br />Emereencv coal stockpile area b~TS-2 <br />This site was reseeded in 1998. Russian thistle continues to be a problem on this site. <br />Periodic spraying may be necessary to allow stand establishment. Additional monitoring will <br />be necessary in 2000. <br />Recommendations <br />Species and growth form diversity appear to be good in most of the recent seedings. <br />However, problems do exist where weeds have become established. The weed problems <br />appeaz to be caused by two factors. First, the long-term prevalence on certain sites by <br />Cheatgrass and second, the early establishment by broadleaf weeds. Cheatgrass will continue <br />to be a problem in localized areas where it dominates adjacent undisturbed vegetation. The <br />best method to control broadleaf weeds is to reclaim a site the same year i[ is disturbed when <br />possible. More attention may be required to annual broadleaf weed control on sites prior to <br />reclamation when they cannot be seeded the same yeaz as disturbed. Under certain <br />circumstances herbicides may be necessary and sacrifices made of desirable species. <br />
