' Vegcration Sampling For 1992 ' "hits" were used to estimate total vegetative cover for each transect according to equation 2. This data is included in Appendix 2. t Parent Totar Vry. Carr . No. Ala on vegaaaon ~21 btal wander aJ po4ea The composition of plant species in each area was evaluated using data acquired from the ' vegetative cover transects. Data from the transects were used in equation 3 to determine the relative cover of each species detected. This data is included in Appendix 2. ' % Rtlarive Cover of Species X = % Cover of Species X ~3) % Tonal Veg. Cover 1 ' Woody plant density was determined through observation of plants along each cover transect. Density data was estimated from two meter wide belts, one meter on each side of the cover transect. Woody plant hits were recorded at the same time as cover data. ' Essentially, no woody plants were recorded during the study. Results ' Since the seeding of the reference plots was completed in the late summer of 1990, the 1992 vegetation sampling occurred toward the end of the second growing season. As a result, sampling indicates that the vegetative stand has not matured. This is apparent by the high percentage of annual forbs which exist on the plots. However, many small grasses were observed under the annual forbs which should become dominant in the 1993 growing season. One aspect which needs to be examined in future studies is the lack of woody plants observed during the 1992 sampling. Woody plants are important because they represent one of the revegetation success criteria. This aspect will be observed closely during the 1993 sampling.
