n <br />U <br />In accordance with the Mined Land Reclamation Division's <br />"Guidelines for Compliance with Land Use and Vegetation <br />Requirements of the Colorado Mined Land Reclamation Board for Coal <br />Mining, October, 1988", a minimum of 10 samples were collected in <br />the two reference areas while at least 15 samples were taken in the <br />three major community disturbed areas. Samples were collected in <br />each area until sample adequacy was reached or to a maximum of 50 <br />samples, whichever was less. In the case of reference areas, woody <br />stem density samples were collected to sample adequacy or to a <br />maximum of 35 samples as was agreed to by the Division. Woody <br />plant density began in late AprilJearly May while cover and <br />production sampling began in early June. <br />Total Vegetative Cover: <br />• Total vegetative cover was sampled using an optical point <br />frame developed by Esco Associates. Point sitings were located <br />along a 50 meter transect stretched out from the sample point <br />location in a direction as described above. The 50 points per <br />transect (one point at each one meter interval) comprise a single <br />sample unit. Cover was identified by species, or as rock, litter, <br />or bare ground. For the purposes of estimating the total <br />vegetative cover, only first hit data were collected. species <br />composition and diversity was determined from cover data. <br />Woody Plant Density: <br />Woody plant density was estimated using elongated quadrats. <br />4 - <br />u <br />
