Litter was <br />considered to be any organic material that had fallen, or had begun to fall to the soil surface. Standing <br />dead was any dead plant material that was produced in previous years but which was still standing and <br />had not lodged or broken off to become litter. Inorganic material greater than 1 cm in diameter was <br />considered rock. The cover sampling points were optically projected using a Cover -Point Optical Point <br />Projection Device developed by ESCO Associates. 50 m transects were randomly located and randomly <br />oriented in the reclaimed and reference areas. One hundred points were collected along each transect. <br />At each meter along the 50 m length, points were projected 0.5 m to the right and 0.5 to the left of the <br />transect, thus minimizing trampling effects. <br />First hit interceptions were used to calculate absolute top layer foliar cover (see FIRST HIT AVERAGE <br />COVER column in data tables) by dividing the number of interceptions for a particular species or ground <br />2 <br />
