Sage Creek Mine February 2009 <br />. effect of surface disturbance at the closer nest sites (including the Swainson's hawk nest site), <br />even though each of these species is fairly tolerant of human activity. <br />Due to the location and type of proposed mine development, the relatively common nature of the <br />existing habitats and lack of critical or unique native habitats within the proposed permit area, the <br />additional past and present energy development in the immediate vicinity, and the intent of the <br />Sage Creek Mine to continue to implement all appropriate wildlife monitoring and mitigation plans <br />prior to and /or during mine operations, significant impacts to wildlife are expected to be limited <br />overall. Development of the Sage Creek Mine will result in minimal short-term habitat loss for <br />some species, but careful reclamation efforts on -site and additional habitat enhancements off -site <br />should allow for their eventual recovery in disturbed areas. The current wildlife monitoring <br />programs undertaken by Seneca Coal Company and Twentymile Coal Company and adjacent <br />mine operators have provided an abundance of data concerning the historic and current habitat <br />use and availability within and surrounding the Sage Creek Mine study area. These efforts will <br />continue to ensure adequate monitoring of existing populations and the ability to detect and <br />address potential future conflicts between wildlife and mine activities. <br />U <br />6.0 REFERENCES <br />Clark, T.
