BLack-Eooted Ferret <br />This species is closely associated with prairie dog colonies where i[ <br />relies on these rodents as important prey items. Based on the baseline <br />wildlife data and recent discussions with the mine perso~u~el, there are <br />Rio kiiuwn prairie dog colonies on or near the mine site. OS[•(RE uses this <br />fact to conclude that the proposed action would not affect the <br />black-Eooted Ferret. <br />Colorado SquawEish and Humpback Chub <br />While these species do not occur on the Edna site, the proposed action <br />would aFEect water resources that contribute flow to the Upper Colorado <br />River Basin. Since the USFiVS has stated tf~at any water depletion in the <br />Basin could aFEect these fishes, OSPff2E has evaluated the proposed ac tio~i <br />Eor potential water depletion. OS~QtE has determined that the proposed <br />action would result in an average annual depletion of 28 acre-feet. <br />OSbIRE hereby requests a biological opinion For the potential effects of <br />this depletion on the listed Eish species. <br />Summary <br />OSill2E has concluded that the proposed action would not affect listed <br />terrestrial species, but requests a biological opinion for the humpback <br />chub and Colorado squawfish. <br />IE you have any questions, please contact Don tlenne at (F'P5) 56d-2718. <br />
