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