• Within the post-mine vegetative community, the food component for brood <br />reazing will be provided by insects and succulent vegetation on reclaimed azeas eazly <br />in chick development. Later into the summer months, as food sources dry up on the <br />upland slopes, food will be available near water impoundments and drainage bottoms <br />being returned to the post-mining topography. The literature indicates no optimum <br />distance between nesting sites and food sources. Evidently, the location of nesting <br />Sites are independent of food sources, rather, the nesting locations aze based on <br />available cover, and the grouse movements are tied to the availability of succulent <br />vegetation. <br />Additional Mi~ation Measures <br />The pre-planning for a minimum amount of annual disturbance, the establishment of <br />herbaceous species, the replacement of native shrub species, and habitat improvement <br />techniques aze the most important azeas for minimizing impacts to wildlife, several other <br />protection measures are in effect. <br />Electric power lines located in the permit azea will be constructed in accordance with the <br />requirements of Section 4.18 to minimize potential electrical hazards to large raptors. <br />Vehicle use within the permit area is limited to the active mining azea and the various support <br />facilities. Off-road vehicle use is kept to a minimum and is usually only authorized for <br />surveying, environmental data collection and monitoring, security, etc. Travel by foot, which <br />• causes much more disturbance to wildlife than vehicle traffic, is highly unlikely outside <br />active mining areas. <br />Hunting with firearms inside Colowyo's Federal lease is allowed and is strictly managed by <br />Colowyo. <br />Speed limits in the mine azea aze limited to reduce the likelihood of collisions between <br />vehicles and <br />2.05-72 Revision Date: 1/26/05 <br />Revision No.: MR-69 <br />
