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 sites that were sampled in 1993 were in the same general <br />locations ae those sampled in 1989, 1990, 1991 and 1992. Data were <br />recorded ae ^hite" on vegetation (recorded by species), litter, bare <br />soil or rock. The data were summarized by computing mean cover, <br />relative cover (percent of total vegetation cover attributed to each <br />species), frequency (the number of transacts of occurrence by a species <br />divided by the total number of traneecte), and relative frequency <br />(percent of the total number of traneecte of occurrence attributed to <br />each species. Relative cover and relative frequency were summed to <br />obtain an importance value on which all species were aerially ranked. <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 />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 />RESULTS <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 />-2- <br />
