This area is not known to be used <br /> exclusively for activities critical to the life cycles of wildlife that <br />' require special consideration. <br /> ii) Upon the establishment and maturation of naturaliy occurring <br /> vegetation, the habitat will be managed as it was before the <br /> proposed activity was begun. <br />' D. Topsoil preservation: <br /> i) Where present, topsoil will be removed prior to gravel mining and <br /> stockpiled in a section of the phase area designated for stockpile <br />' storage. If stockpiled for more than a year, the topsoil (interim) <br /> seed mixture will be applied during the growing season that <br />' follows stockpiling. <br /> ii) After trees are harvested for firewood, the remaining shrubs, fortis <br /> and tree limbs along with grasses will be chipped and incorporated <br /> into the topsoil stockpile. Alternatively, the materials will be piled <br /> (without being chipped) above the ]ay back slope to be pushed <br /> downwazd onto the slope by a bulldozer. This larger material <br />' would provide greater slope stability, as material will key into <br /> slope. The presence of larger woody debris better mimics a natural <br /> forest condition. When the first phase is nearing completion; <br />' clearing will begin on the second phase. Work will be done <br /> similar to phase one, with the exception of transplanting smaller, <br /> <br />' Hydrosphere Rcsourcc ConsulunLS, 1002 Walnut Suite 200, Boulder, CO 80302 <br />
