Plant material produced during the current growing season and still <br />standing was tallied by species. Litter was considered to be any organic material that had fallen, <br />or had begun to fall to the soil surface. Standing dead was any dead plant material that was <br />produced in previous years but which was still standing and had not lodged or broken off to <br />become litter. Inorganic materials greater than 1 cm in diameter were considered rock. The <br />cover sampling points were optically projected using a Cover-Point Optical Point Projection <br />Device developed by ESCO Associates. The 50 m transects were randomly located and oriented <br />in the reclaimed and reference areas. One hundred points were collected along each transect. A <br />pair of points were collected every meter with points sampled on opposite sides of each transect, <br />0.5 m from the transect. <br />First hit interceptions were used to calculate absolute top layer foliar cover (see COVER column <br />in data tables) by dividing the number of interceptions for a particular species or ground cover <br />type by the total number of points taken (100). First hit relative vegetation cover was calculated <br />by dividing first hit 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 all hits (first-hits <br />0 2
