<br />VI. Revegetation <br />A. The Division proposes to approve the use of introduced species in the reclamation <br />seed mix. The applicant has submitted information which shows that the <br />introduced species are desirable and necessary to achieve the approved <br />post-mining land use, and are not poisonous or noxious (4.15.2). <br />B. The Division proposes to approve the use of a cover crop as a means to meet soil <br />stabilization requirements (4.15.4). <br />C. Methods to measure herbaceous cover and production, species diversity, and <br />woody plant density are discussed .in the permit application. These techniques <br />include: <br />New Horizon Mine 1 <br />1. Cover -Point intercept along a randomly located line transect or ocular <br />estimates in randomly located sample quadrants. <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 <br />estimates in randomly located sample quadrants. <br />2. Production -Clipping of one-meter-square plots, oven drying and weighing <br />or weighing of baled hay, sampling bales and then oven drying and weighing <br />of samples. The technique used depends on the end land use of the area <br />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 <br />4.15.10 have been met, the following success standards will be used: <br />19 <br />
