The Snedecor-Cochran sample size <br />] adequacy formula was used that is listed on page 15 of the <br />' Division's "Guidelines for Compliance with Land Use and <br />Vegetation Requirements of the Colorado Mined Land Reclamation <br />Board for Coal Mining, October, 1988". <br />I The grassland area was sampled to adequacy for cover. <br />Ten samples were collected: based on total cover, only 3.9 <br />I samples were required. When the grassland community is <br />subdivided into "flat" and "slope", the 2 and 8 samples placed <br />in these areas still exceed the sample adequacy values (0.4 <br />I 7 <br />
