1 <br />fifty points per transect. Twenty traneecte were sampled in the entire <br />' area (six in the area seeded in 1984 and fourteen in the area seeded in <br />1988). The Bites that were sampled in 1996 were in the same general <br />' locations as those sampled in previous years. Data were recorded as <br />' "hits" on vegetation (recorded by species), litter, bare soil or rock. <br />The data were summarized by computing mean cover, relative cover <br />' (percent of total vegetation cover attributed to each species), <br /> frequency (the number of traneecte of occurrence by a species divided by <br />' the total number of transects) <br />and relative frequency (percent of the <br /> , <br />' total number of traneecte of occurrence attributed to each species. <br /> Relative cover and relative frequency were summed to o btain an <br />t importance value on which all species were serially ra nked. <br /> Information on species diversity was obtained by keeping track of <br />' all the observed species in each of the sampled areas. The mean number <br /> of species per transect was also determined. Species that were observed <br />' <br /> in each of the areas but were not encountered ae hits on the transect <br />' lines, appear in the cover data tables as species with less than one <br /> percent mean cover and zero percent frequency. <br />' <br /> RESULTS <br />' <br /> Complete cover summaries for the 1984 area, the 1988 area and the <br />' two areas combined are presented in Tables 1, 3 and 5, respectively. <br /> The key cover values are summarized below (+~- values equal the standard <br />' deviation): <br />1 <br /> <br /> -2 <br />' <br />
