None of these featwes were identified in the <br />exploration drill hole sites evaluated. While it is possible that any bat species may use <br />areas above the exploration drill hole locations for foraging, it is highly unlikely that any <br />negative impact to the bats would occur, if they are present. <br />Bald Eagle <br />No bald eagle individuals or bald eagle nests. or roosting areas were observed dwing the <br />field investigations. A review of the Colorado State University Natwal Diversity <br />Information Sowce database (www.ndis.nrel.colostate.edun recommended by the <br />Colorado Division of Wildlife reveals that ba]d eagle usage is generally restricted to the <br />ripaian comdor along the North Fork of the Gunnison River in this azea. The <br />exploration drill hole Locations are two to three miles north of the riparian corridor. <br />Therefore, there is little likelihood of negatively impacting bald eagles. <br />• <br />-4- <br />
