• First hit interceptions were used to calculate absolute top layer foliar cover <br />(see COVER column in data tables) by dividing the number of interceptions for a <br />particular species, or ground cover type by the total number of points taken <br />(100). First hit relative vegetation cover was calculated by dividing first hit <br />absolute cover for each species by the total first hit vegetation cover. All-layer <br />absolute cover (COVER-ALL column in data tables) was calculated by dividing <br />all hits (first-hits and additional-hits).for particular species by the total number <br />of points taken (100). In addition, all-layer relative cover was calculated using <br />all hits for particular species divided by the total hits accumulated during <br />sampling of the transect. " <br />Herbaceous Production Sampling <br />Herbaceous production sampling was undertaken in the 1991/1993 <br />Reclamation Area of the Seneca Il-W Mine. Herbaceous production sampling <br />• was accomplished using one-half square meter (0.5 m2) circular quadrats within <br />which all herbaceous growth in a vertical production was removed by clipping, <br />and placed in labeled paper bags. When alfalfa (Medicago saliva) occurred, it <br />was placed in separate, labeled bags. Clipped material was returned to the <br />ESCO laboratory and dried at 105 °C for 24 hours, then weighed to the nearest <br />0.1 gm. Fifteen samples (clip plots) were undertaken in the 1991/1993 <br />reclaimed area. <br />Shrub Density Sampling <br />Shrub density sampling was undertaken in the 1991/1993 Reclamation Areas <br />of the Seneca II-W Mine. Shrub density was measured within 2 X 50 m <br />quadrats ("belt transacts") oriented along the cover transect (where a cover <br />sample was also taken). In the two reference areas, no shrub sampling was <br />conducted, since it had been sampled very extensively in previous years and <br />• resulting data would not have an effect on a woody plant density performance <br />3 <br />
