For the combined data for the two reclaimed areas (Table 6), <br />' these four species accounted for 92.6 percent of the cover by all <br /> species. In all, 26 species were observed in the reclaimed areas. <br /> There are some differences between the areas reclaimed in 1984 and 1988. <br /> In the 1984 area, green needlegrass (Stipa viridula) and big sagebrush <br />t are more abundant than in the 1988 area <br />Russian wildr <br />e and thickspike <br /> . <br />y <br />' wheat grass are more abundant in the 1988 area than they are in the 1984 <br /> area. The greater abundance of big sagebrush in the 1984 area may be <br />' related to the differences in ages of the two areas, however the cover <br /> data collected aver the past six years suggests that big sagebrush is <br />' increasing in cover very slowly in the 1988 area. In 1994 <br />big <br /> , <br />' sagebrush was the major species in the area seeded in 1984 and accounted <br /> for 64.5 percent of the cover by all species in that area. Mean cover <br /> for big sagebrush increased from 8 percent in 1993 to 20 percent in <br /> 1994. While this difference may be related to slight differences in <br />' sample transect location, it is clear that, on the basis of general <br />1 <br />' -3- <br />
