A ERC DPG Site <br /> Threatened and Endangered Species Screening <br /> vegetation community within the survey area occupies approximately 20% along the Cache la Poudre in <br /> the northern portion of the survey area and along the South Platte in the eastern portion of the survey <br /> area.This habitat is a forested riparian area exhibiting overstory canopy trees, midstory shrubs and dense <br /> herbaceous understory cover. Overstory canopy trees and midstory shrubs,situated near an agricultural <br /> landscape, can provide potential roosting and nesting habitat for visiting and residential raptors and <br /> smaller migratory birds. The Western Cattail Marsh vegetation community within the survey area <br /> occupies a small percentage of the survey area (4%) in the north central portion of the survey area.This <br /> habitat is dominated by narrowleaf cattail (Typha angustifolia) and saltgrass (Distichilis spicata). Cattail <br /> marsh provides unique valuable habitat qualities for certain species, including nesting materials,foraging <br /> opportunities, and a seasonal water source. The remaining 1% of the land cover consists of roads, <br /> structures,and surface water. <br /> Some local wildlife species that may use this habitat within the Survey area includes Canada geese(Branta <br /> canadensis), common mallard (Anas platyrhynchos), red-winged blackbird (Agelaius phoeniceus), <br /> mourning dove (Zenaida macroura), killdeer (Charadrius vociferous), western meadowlark (Sturnella <br /> neglecta), Great Plains toad (Anaxyrus cognatus), snapping turtle (Chelydra serpentina), garter snake <br /> (Thamnophis sp.), and various other species of fish and aquatic invertebrate. <br /> • Generally,there are features on the survey area and the surrounding area that provide general habitat <br /> for local songbirds, raptors, waterfowl, amphibians, reptiles, aquatic invertebrate and small to mid- <br /> size mammals. However,the majority of the habitat on survey area is classified as cultivated cropland <br /> and ruderal herbaceous vegetation which is somewhat degraded from a wildlife perspective by <br /> historic and current land use practices. Within the survey area, the Western Great Plains Riparian <br /> Woodland, Shrubland, and Herbaceous and Western Cattail Marsh communities occupy a smaller <br /> percentage of the survey area; however, these communities do provide significantly higher value <br /> wildlife habitat,specifically along the Cache La Poudre River. <br /> 5.0 MIGRATORY BIRD TREATY ACT <br /> Migratory birds are protected under the Migratory Bird Treaty Act(MBTA)(16 U.S.C.730-712). The MBTA <br /> makes it illegal for anyone to take, possess, import, export, transport, sell, purchase barter, or offer for <br /> sale, purchase, or barter any migratory bird, or the parts, nests, or eggs of such a bird except under the <br /> terms of a valid permit issued pursuant to Federal regulations. In Colorado, all birds except for the <br /> European starling (Sturnus vulgaris), house sparrow (Passer domesticus) and rock pigeon (Columba livia) <br /> are protected under the MBTA.A total of 523 migratory bird species are known to occur in the Mountain- <br /> Prairie Region (USFWS Region 6, Montana, Wyoming, Utah, North Dakota, South Dakota, Nebraska, <br /> Kansas and Colorado); 320 of the 523 migratory bird species are known to breed in USFWS Region 6. <br /> Migratory birds likely exist within the survey area. The mature overstory cottonwood trees and open <br /> shrub midstory within the Western Great Plains Riparian Woodland, Shrubland and Herbaceous <br /> vegetation community on the eastern portion of the survey area provide potential habitat for migratory <br /> birds. Several migratory birds were also directly observed within the survey area, including mourning <br /> dove, black-billed magoie(Pica hudsonia),American white pelican(Pelecanus erythrorhynchos),American <br /> robin (Turdus migratorius), western grebe (Aechmorphorus occidentolis), great blue heron (Ardea <br /> herodias), mallards, western meadowlark, red-winged blackbird, black-capped chickadee (Poecile <br /> atricapillus),northern flicker(Colaptes auratus),Say's phoebe(Sayornis saya),blue jay(Cyanotta cristata), <br /> yellow-rumped warbler (Setophaga coronata), and chipping sparrow (Spizella passerina). Such birds are <br /> 10 <br />
