Cover Sampling
Cover data were collected along 50 m transects using a point -intercept method in which data were
recorded as interceptions of a point with a plant species, litter, standing dead plant material, soil, or rock.
Plant material produced during the current year and still standing was tallied by species. Litter was
considered to be any organic material that had fallen or had begun to fall to the soil surface. Standing
dead was any dead plant material produced in previous years, but which was still standing and had not
lodged or broken off to become litter. Inorganic material greater than 1 cm in diameter was considered
rock. The cover sampling points were optically projected using a Cover -Point Optical Point Projection
Device developed by ESCO Associates. The 50 m transects were randomly located and randomly
oriented in the reclaimed and reference areas. One hundred points were collected along each transect.
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
transect, thus minimizing trampling effects.
First hit interceptions were used to calculate absolute top layer foliar cover (see FIRST HIT AVERAGE
COVER column in data tables) by dividing the number of interceptions for a particular species or ground
cover type by the total number of points taken (100). First hit relative vegetation cover was calculated by
dividing first hit absolute cover for each species by the total first hit vegetation cover (see FIRST HIT
