<br />Ycgetation Sampling For ]993 <br />' counted. Woody plants whose branches and leaves crossed into the transect area but whose <br />stems were not rooted within the belt were not counted. <br />Results <br />' Mean vegetation cover values for both the reclaimed and reference areas are summarized in <br />Table 2. Data summaries for each area are provided in Tables 8A and 9A in the data Appendix. <br />The raw data for each transect is found in Tables 8B and 9B in the Appendix. <br />' TABLE 2 <br />Summary of Sample Adequacy Calculations <br />Canadian Strip Mine - 1993 Point-Intercept Transects <br />Computed <br />Mean Vegetation Standard Actual Adequate <br />Area Cover (Percent) Deviation Sample Size Sample Size <br />' Reclaimed 41.4 5.13 10 5.1 <br />Area IV <br />Reference 56.0 4.90 6 3.1 <br />AREA <br />1 <br />The survey showed that 41.4 percent of the reclaimed area was covered by vegetation. Bare <br />' ground accounted for 24.9 percent of the surface area, while little and rock comprised 32.5 and <br />1.2 percent, respectively. <br />' In terms of relative vegetative cover, perennial grasses accounted for the majority of the cover <br />(76.1 percent). Cool season wheatgrasses (Agropyron spp.) accounted for 72.0 percent of the <br />relative cover in the reclaimed area. Perennial forbs accounted for 23.4 percent of relative <br />cover while shrubs comprised only 0.5 percent. No annual grasses or forbs were sampled in <br />the reclaimed area. <br />' The absolute vegetative cover value of 56 percent on the reference area was 14.6 percent greater <br />than on the reclaimed area. Litter and bare soil comprised 25.0 and 13.7 percent of the absolute <br />' cover, respectively. In terms of relative vegetative cover, subshrubs and shrubs comprised 49.4 <br />percent in the reference area, with perennial grasses being the next dominant vegetative form <br />~ ~~® <br />' S <br /> <br />
