New Horizon Mine 1 <br /> 1. Cover - Point intercept along a randomly located line transect or ocular estimates <br /> in randomly located sample quadrats. <br /> 2. Production - Clipping of 1 meter squared plots, oven drying and weighing. <br /> 3. Species diversity - Qualitative comparisons using cover and frequency values. <br /> 4. Woody plant density - Counting within randomly located belt transects. <br /> New Horizon Mine 2: <br /> 1. Cover- Point intercept along a randomly located line transect or ocular estimates <br /> in randomly located sample quadrats. <br /> 2. Production - Clipping of one-meter-square plots, oven drying and weighing or <br /> weighing of baled hay, sampling bales and then oven drying and weighing of <br /> samples. The technique used depends on the end land use of the area sampled. <br /> 3. Species diversity - Qualitative comparisons using cover and frequency values. <br /> 4. Woody plant density - Counting within randomly located belt transects. <br /> The Division proposes to approve these techniques (4.15.7(1)). <br /> D. In order to demonstrate that revegetation success criteria of 4.15.8,4.15.9, and 4.15.10 <br /> have been met, the following success standards will be used: <br /> New Horizon Mine 1: <br /> 1. Cover- Reclaimed areas will be compared to the established reference area or a <br /> technical standard of 43.9 percent ground cover(vegetation and litter) depending <br /> on whether the area has been previously mined or not. <br /> 2. Production - Reclaimed areas will be compared to Natural Resources <br /> Conservation Service potential productivity values (technical standards) for <br /> Shavano (500 lbs./ac.)or Persayo(250 lbs./ac.) soil series depending on end land <br /> use. <br /> 3. Species diversity - Reclaimed areas will achieve a standard of three grasses, one <br /> forb and one shrub with relative cover values greater than three percent. The <br /> 21 <br />
