Since the vegetative cover will transform naturally from a high alluvial dry land cover to a wetland type cover, exact standards for reclamation success cannot be determined today. Therefore, BME proposes the following standards apply to the reclaimed alluvial well area: Cover and Production Cover and production will be compared to the reference area at the time of reclamation. Cover and production data will be taken directly from the reference area as described in Section t/,E of the permit for comparison to the reclaimed area. The statistical comparisons listed in Section V.E will then apply to confirm reclamation success. Woody Plant Density As a minimum standard, BME agrees to establish 1000 stems/acre. This standard may be adjusted due to expected changes in the reference area over the mine life. The standard will only be adjusted in consultation with DMG at the time of reclamation.
