imposed upon the species by the proposed actions. The plan to minimize the effects is herein <br />• presented by species. <br />Waterfowl - Waterfowl are prime species due to their value as game. Many species are summer <br />breeding residents but the potential for summer breeding is great. They are ubiquitous but restricted <br />to waterways or impoundments. <br />Ferruginous Hawk - The major thrust of the potential impact will be on the nesting success of this <br />bird. Ferruginous hawks do not tolerate human activity close to the nest during incubation and <br />disturbance may result in reduced nestling survival or nest desertion. Due to their habits of nesting <br />in low juniper trees and on the ground, this hawk is vulnerable to unintentional as well as intentional <br />harassment. <br />To minimize the detrimental impacts to this species, employees will be restricted to improved road <br />use. <br />Golden Eagle - Golden eagles are common and often seen in the area of potential impact, but <br />unlike ferruginous hawks, golden eagles are very tolerant of human activity, even during nesting. <br />There are three known active nesting sites in the vicinity of the projected mine portal, but it is <br />unlikely that more than one is used in any given year. <br />• Since it was believed by Dr. Clayton M. White that the nest sites would not be abandoned during <br />portal activities, no specific measures are planned for the portal to accommodate the golden eagle. <br />However, no surface exhaust or ventilation fans will be located within 1/4 -mile of the known nesting <br />sites. <br />Bald Eagle - Impact to northern bald eagles is not a major concern in this project. <br />Perearine Falcon - Impact to peregrine falcons is not a concern in this project. <br />Sage Grouse - The major concern of potential impact to sage grouse is the disruption of normal <br />reproductive behavior by destroying "leks ". Since no '9eks" have heretofore been located, the <br />applicant will support a thorough field research effort to locate '9eks ". If '9eks" are observed, <br />appropriate mitigation measures will be developed with the assistance of Colorado Division of <br />Wildlife. <br />Ring- necked Pheasant - Impact to this species is not a concern within the scope of this project. <br />Mountain Plover - Since the mountain plover is considered an accidental visitor or straggler in the <br />area of potential impact it is of little concern. <br />• Technical Revision #68 (01/2011) IV -4 9 <br />
