This buffer shall extend the length of the area proposed for reclamation north of the river. This buffer shall include preservation of the freshwater marsh area. A revegetation plan utilizing native trees and shrubs shall be developed to provide effective screening from mining and agricultural activities, and enhance wildlife habitat within.the buffer zone. This plan shall be prepared by a qualified biologist and submitted to the County for approval prior to project construction. i At a minimum, the revegetation plan shall replace lost trees within the riparian corridor by planting trees within the buffer as follows: Replacement at a ratio of five to one shall be required for valley oaks and three to one for other native trees six inches or greater in diameter, measured at 4.5 feet above ground level. Replacement trees shall be one F 136
