live vegetative cover excluding annual weeds. One perennial forb should <br />comprise 5% of total live vegetative cover excluding annual weeds. <br />For oak/pinion areas, success will be demonstrated for cover and production <br />when the reclaimed area is at least 90 % of the reference area and meets the <br />90% confidence interval using a one-sided T-test. The woody stem density <br />standard is 500 stems per acre. Species diversity standards are 2 cool <br />season grasses and 1 warm season grass comprising 5 to 30 percent of total <br />live vegetative cover excluding annual weeds. One perennial forb should <br />comprise 5% of total live vegetative cover excluding annual weeds. <br />E.

The areas are depicted on Map <br />2.04.10-1 Vegetation Community Map. <br />F. The reference areas will be utilized to determine revegetation success in a <br />manner that the Division finds acceptable (4.15.7(4)). <br />X11. Post-mining Land Use <br />No specific approvals are granted under this section. <br />XIII. Protection of Fish, Wildlife and Related Environmental Values <br />A.
