<br />4423 <br /> <br />Without prairie dog towna, it ia aaaumed there would be <br />no ferrets to be affected. <br /> <br />. <br /> <br />A few American peregrine falcons nest in the precipitous <br />cliffs on Glenwood Canyon. This migratory endangered <br />bird, may occasionally be seen near Ruedi, Turquoise, <br />Twin Lakes, or Clear Creek Reservoirs in search of water- <br />fOwl, their primary food. However, the Fish and Wildlife <br />Service does not feel that management of Project lands is <br />either feasible or justifiable for these birds (FWS, <br />letter of September 8, 1971). <br /> <br />There is one nesting pair of bald eagles in Colorado that <br />could be the southern subspecies (FWS, personal communica- <br />tion, February 25, 1975). These are wide ranging birds <br />that could be observed anywhere in the Project area, <br />especially after they have fledged their young. Winter- <br />ing bald eagles have also been observed in the Arkansas <br />River Valley between Rocky Ford and La Junta (FWS, letter <br />of September 8, 1971). These eagles roost in tall treea, <br />such as cottonwoods, and feed on aick or maimed waterfowl. <br />These would be affected by the removal of roost treea. At <br />most, 5 tree a could be removed during construction of the <br />Arkansas Valley Conduit to provide for river croasings. <br />There is one crossing in the above-reference river reach. <br />However, this wintering population is composed of northern <br />bald eagles (Haliaeetus leucocephalus alascanus), which <br />are not listed as endangered. Bald eagles are also pisci- <br />vorous and could gain feeding areas due to the increase in <br />lacustrine fisheries, but would suffer no adverse effects <br />from the Project due to the elimination of critical habitat. <br /> <br />. <br /> <br />Most of the speciea of concern occur outaide of the area <br />of influence or only within the Project area on occasion. <br />Mammals that inhabit the mountainous region of the Project <br />area include the Canada lynx (collection system and Mt. <br />Elbert area), wolverine (collection system), and pine <br />marten (7000 13000 feet, both slopes). The lynx and <br />wolverine are"wilderness species. As such, they could <br />be driven from the collection system feature sites if <br />heavy concentrations of people use this area. The access <br />roads could provide for this, resulting in a secondary <br />impact. However, there would be little physical loss of <br />habitat by development of roads or other Project features <br />and there would be no habitat loss that is critical. The <br />pine marten would not be similarly affected since they show <br />little fear of man (Lechleitner, 1969). <br /> <br />. <br /> <br />IV-33 <br />
