• Determining Revegetation Success <br />Quantitative Sampling. -General: <br />There is no reference area to be used in a success comparison. The entire <br />site is included as one unit. Reclaimed parameter values will be compared <br />against technical standards. Sample locations will be selected randomly from <br />within the reclaimed area. Cover sample locations will be drawn from maps <br />using a regularly spaced grid (probably 50 x 50 ft. Sample points will be <br />located in the field through the use of a compass and pacing. Cover transacts <br />will originate from sample locations. For production sampling, in which a much <br />greater number of samples will need to be collected, sample locations will be <br />drawn from a smaller (25 x 25 ft) grid. Approximate sample locations will be <br />marked on a map. Sample procedures will be discussed with the Division prior <br />to initiating any sampling program. <br />Total Vegetative Cover: <br />Total vegetative cover will be estimated using an optical point frame or point <br />laser. Point sitings will be located along a 25 meter transect stretched out either <br />• northwest, northeast, southwest, or southeast of [he sample location (the <br />direction was randomly selected from among the four possibilities) or at a <br />slightly different direction (e.g., NNE, etc.) when one of these directions is not <br />possible. <br />The 50 points per transect (one point at each half meter interval) will comprise <br />a single sample unit. Cover will be identified by species, or as rock, litter, or <br />bare ground. For the purposes of estimating total vegetative cover, only first hit <br />data will be used. <br />Total Herbaceous Production: <br />In the reclaimed area, plots will be 1/2 meter by 1/2 meter in size. <br />All current annual herbaceous production inside the production plots will be <br />clipped, separated according to life form, and bagged. The four life forms will <br />include perennial grasses, perennial fortis, annual species, and noxious weeds. <br />Production data will not be the basis of species diversity, and therefore sorting <br />by species is unnecessary. All production samples will be oven dried at 110 <br />degrees Fahrenheit to a constant weight. Biennial species will be included with <br />annual species. <br /> <br />Mid-Term Review 3/21/01 184-15 <br />
