<br />watershed, but no Mexican spotted owls have been located to date. A <br />complete survey of the South Fork canyon and lower Main Fork was completed <br />in 1994 for the Galloping Goose Trail project, and no Mexican spotted awls <br />were located. <br />The proposed action will not have any direct effects upon suitable habitat <br />within the upper San Miguel canyon. All activities are located within the <br />river channel and floodplain. Based upon the lack of known species <br />occurrence or impact to any suitable habitat, the proposed action will have <br />no effect upon the Me:ican spotted owl. <br />Southwestern willow flycatcher - ~pidonaz traillii eztimie <br />endangered species <br />The southwestern willow flycatcher is one of five subspecies of the willow <br />flycatcher currently recognized. As a group, willow flycatchers breed <br />throughout most of the United States, and migrate to Mexico and Central <br />America for the winter. The breeding range of the southwestern subspecies <br />includes southern California, southern Nevada, southern Utah, Arizona, New <br />Mexico, western Texas, southwestern Colorado, and extreme northwestern <br />Mexico. <br />Critical habitat for the southwestern willow flycatcher has not yet been <br />designated. The US Fish and Wildlife Service has defined suitable habitat <br />within its range in Colorado to include riparian shrub vegetation at least <br />30 feet wide, 30 feet long, and 5 feet high which is located on streams <br />with 4Z gradients or less, up to 8,500 feet in elevation. Survey protocol <br />has been established, and any willow flycatcher that is identified below <br />8,500 feet elevation will be considered the southwestern subspecies. <br />Surveys conducted by the BLM and Forest Service in 1995 detected willow <br />flycatchers in three locations in the San Miguel and Dolores watersheds. <br />The closest location to the project area is at the confluence of Saltado <br />Creek and the San Miguel River, approximately 16 miles downstream from the <br />project area. <br />Based upon the above habitat criteria, suitable habitat may have been <br />present within the project area prior to gravel mining operations. The <br />elevation of the river at the confluence is about 8,000 feet, and much of <br />the South Fork is below 8,500 feet in elevation. By reviewing old <br />photographs of the area, it is apparent that side channels with beaver dams <br />and other flooded habitat existed prior to gravel mining. All of this <br />habitat has been lost to the extensive erosion that has occurred in the <br />project area. Remaining suitable habitat has been identified in the South <br />Fork about 3 miles upstream from the confluence. <br />As stated, the proposed action is designed to: 1) halt further headcutting <br />of the channel by installation of grade control structures; 2) reduce <br />accelerated bank erosion; 3) create a single channel and eliminate the <br />braided pattern which now exists; 4) restore aquatic and riparian habitat <br />quality; 5) reduce the potential impact of future flood damage; and 6) <br />restore the visual, aesthetic, biological and physical qualities of the <br />riverine environment. If the objectives are achieved, suitable habitat for <br />the southwestern willow flycatcher should also be eventually restored. <br />This would result in a beneficial effect to the species through increased <br />available habitat. <br />Northern leopard frog - ana pinene <br />Porest Service sensitive species <br />15 <br />
