• 2.05.4(2)(e) <br />Collection and Analysis of Cover Data <br />Cover is estimated using a point-intercept method <br />along randomly located and oriented transects. Fifty points are <br />sampled along the 50-meter length transects. One point is sampled <br />at each meter interval along the transect. Each point is 0.5 meter <br />from the transect and perpendicular to the transect. <br />The sighting device is mounted on an adjustable <br />tripod to facilitate vertical orientation and point stabilization. <br />Fine cross hairs are used in the sighting device to provide optimum <br />point definition. At each sample point, the sighting devise is <br />directed vertically upward if overstory vegetation was present and <br />then downward into the understory community. The first hit along <br />a vertical line is recorded as vegetative (by species), rock, <br />litter or soil. When vegetation is intercepted on the first hit <br />additional hits are taken until soil, litter or rock was <br />intercepted. First hits are used in calculating the absolute <br />percent cover. <br />n <br />U <br />• <br />2.05-26ii September 1994 <br />
