i <br /> 1 r <br /> B. The Division proposes to approve the use of a cover crop as a means <br /> to meet soil stabilization requirements (4. 15.4) . <br /> C. Methods to measure herbaceous cover and production, species <br /> diversity, and woody plant density are discussed in the permit <br /> application. These techniques include: <br /> New Horizon Mine 1 <br /> 1 . Cover - Point intercept along a randomly located line transect or <br /> ocular estimates in randomly located sample quadrats . <br /> 2. Production - Clipping of 1 meter squared plots , oven drying and <br /> weighing. <br /> 3. Species diversity - Qualitative comparisons using cover and <br /> frequency values . <br /> 4. Woody plant density - Counting within randomly located belt <br /> transects . <br /> New Horizon Mine 2 <br /> 1 . Cover - Point intercept along a randomly located line transect or <br /> ocular estimates in randomly located sample quadrats . <br /> 2. Production - Clipping of 1 meter squared plots, oven drying and <br /> weighing or weighing of baled hay, sampling bales and then oven <br /> drying and weighing of samples. The technique used depends on <br /> the end land use of the area sampled. <br /> 3. Species diversity - Qualitative comparisons using cover and <br /> frequency values . <br /> 4. Woody plant density - Counting within randomly located belt <br /> transects . <br /> The Division proposes to approve these techniques (4. 15.70 )) . <br /> 0. In order to demonstrate that revegetation success criteria of 4. 15A, <br /> 4. 15. 9, and 4. 15. 10 have been met, the following success standards <br /> will be used: <br /> New Horizon Mine 1 <br /> 1 . Cover - Reclaimed areas will be compared to the established <br /> reference area or a technical standard of 43.9 percent ground <br /> cover (vegetation and litter) depending on whether the area has <br /> been previously mined or not . <br /> 2. Production - Reclaimed areas will be compared to Soil <br /> Conservation Service potential productivity values (technical <br /> standards) for Shavano (500 lbs . /ac . ) or Persayo (250 lbs . /ac. ) <br /> soil series depending on end land use. <br /> -20- <br />
