For the combined data for the two <br />' reclaimed areas (Table 6), these four species accounted for 95.7 percent <br />of the cover by all species. In all, 26 species were observed in the <br />' reclaimed areas. There are some differences between the areas reclaimed <br />in 1984 and 1988. In the 1984 area, green needlegrass and big sagebrush <br />' are more abundant than in the 1988 area. Russian wildrye and thickspike <br />wheatgrass 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 over the past eight years suggest that big sagebrush is <br />' increasing in cover very slowly in the 1988 area. In 1996, big <br /> sagebrush was the major species in the area seeded in 1984 and accounted <br /> bl <br />l <br />i <br />h 1 <br /> n t <br />at area (Ta <br />e <br />for 73,3 percent of the cover by a <br />l species ). <br />' Mean cover for big sagebrush increased from 8 percent in 1993 to 20 <br /> percent in 1994 and 22.0 percent in 1996. While this difference may be <br />' related to alight differences in sample transact location, it is clear <br /> that, on the basis of general observations made within the area, big <br />' -3- <br />
