Determining ReveRetation Success <br />Quantitative Sampling -General: <br />d There is no reference area to be used in a success comparison. The entire site is <br />included as one unit. Reclaimed parameter values will be compared against <br />technical standards. Sample locations will be selected randomly from within the <br />reclaimed area. Cover sample locations will be drawn from maps using a regularly <br />spaced grid (probably 50 x 50 ft). Sample points will be located in the field <br />through the use of a compass and pacing. Cover transacts will originate from <br />sample locations. For production sampling, in which a much greater number of <br />samples will need to be collected, sample locations will be drawn from a smaller <br />(25 x 25 ft) grid. Approximate sample locations will be marked on a map. Sample <br />'procedures will be discussed with the Division prior to initiating any sampling <br />'program. <br />Total Vegetative Cover: <br />Total vegetative cover will be estimated using an optical point frame or point laser. <br />Point si[ings will be located along a 25 meter transect stretched out either <br />northwest, northeast, southwest, or southeast of the sample location (the direction <br />was randomly selected from among the four possibilities) or at a slightly different <br />direction (e.g., NNE, etc.) when one of these directions is not possible. <br />The 50 points per transect (one point at each half meter interval) will comprise a <br />single sample unit. Cover will be identified by species, or as rock, litter, or bare <br />ground. For the purposes of estimating total vegetative cover, only first hit data <br />will be used. <br />Total Herbaceous Production: <br />In the reclaimed area, plots will be 1/2 meter by 1/2 meter in size. All <br />current annual herbaceous production inside the production plots will be clipped, <br />separated according to life form, and bagged. The four life forms will include <br />perennial grasses, perennial fotbs, annual species, and noxious weeds. Production <br />data will not be the basis of species diversity, and therefore sorting by species is <br />unnecessary. All production samples will be oven dried at 110 degrees Fahrenheit <br />to a constant weight. Biennial species will be included with annual species. ~ <br />TR May 2002 184-15 <br />
