Fourmile Creek .jpg) Our assessment begins in Four-mile Park, a wide, low-gradient valley at an elevation of 8893’ and ends where Four-mile Creek has its confluence with the Roaring Fork River at an elevation of about 5880’. Surrounding lands are controlled by a mixture of public and private ownership. Headwaters are primarily in public ownership with patches of private in-holdings, while downstream reaches are predominantly under private ownership. Threats to stream ecosystem sustainability issue from both public and private land management. On public lands grazing in riparian areas and recreational impacts degrade riparian vegetation and stream habitat. On private lands throughout the valley land use is transitioning from agricultural use to residential development. Historic overgrazing on private lands has degraded the entire stream ecosystem – some of this habitat is recovering after years of no grazing. Much of the agricultural lands are being converted to residential use in which inappropriate development threatens the integrity of riparian, stream and upland habitat via habitat alteration. Numerous paved and dirt roads are scattered throughout this reach and degrade stream habitat by isolating upland from riparian habitat, causing erosion, stream sedimentation and pollution, and acting as conduits for weed invasion.  |
