<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 sites that were sampled in 1995 were in the same general <br />locations as those sampled in previous years. Data were recorded as <br />r--- - - <br />' "hits" on vegetation (recorded by species), litter /bare eoiror 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 apeciea divided by <br />the total number of transacts), and relative frequency (percent of the <br />' total number of traneecte of occurrence attributed to each apeciea. <br />Relative cover and relative frequency were summed to obtain an <br />' importance value on which all apeciea were aerially ranked. <br />Information on apeciea 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 transact was also determined. Species that were observed <br />in each of the areas but were not encountered as hits on the transact <br />' lines, appear in the cover data tables as apeciea with lase than one <br />percent mean cover and zero percent frequency. .. <br />1 <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 />1 <br /> <br />' -2 <br />
