1.3 Sampling Design <br />Sampling for species diversity, percent cover and production will be conducted <br />using a quadrate method. 1n revegetation azeas at least 20 (9.6 sq. ft.) plots will <br />be randomly located for sampling. A visual estimate of cover will be made for <br />individual species, rock, bare ground, litter, lichens and moss. The number of <br />species per 9.6 sq. ft. plot will be used to determine the diversity of the <br />vegetation. Also, a visual evaluation of soil erosion will be noted, based on <br />evidence of sheet, rill or gully erosion and deposition of soil particles. <br />A double sampling technique will be used in order to deternne herbaceous <br />production. At least five of the 20 plots, per sample unit (i.e. revegetation area <br />or control), will be clipped and individual species bagged. The clipped <br />vegetation will be returned to the lab, oven dried and weighed to the nearest <br />0.01 gram. A con elation between oven dry weights and ocular estimates will be <br />made, and all ocular estimates will be adjusted accordingly. <br />Control vegetation sites will be similazly sampled for comparison. <br />1.4 Method of Analysig <br />Reference areas or representative control sites will be used for comparison to <br />38 <br />~$ <br />
