SEASONAL USE OF AREA <br /> The Project area is expected to be used during spring and fall migration and during winter by waterfowl and <br /> other migratory water birds until the water freezes. Several of the species expected include American wigeon <br /> (Anas americana), green-winged teal (Anas carolinensis), northern shoveler (Anas clypeata), blue-winged teal <br /> (Anas discors), mallard, gadwall (Anas strepera), ring-necked duck (Aythya collaris), Canada geese (Branta <br /> canadensis), cackling geese (Branta hutchinsii), common goldeneye (Bucephala clangula), and ruddy duck <br /> (Oxyura jamaicensis). At the time of the field survey (June 10, 2014), a limited number of waterfowl species <br /> were observed that are likely to nest (mallard), or could nest on-site (pied-billed grebe, redhead). Other birds <br /> that are likely to nest within the Project area include red-winged blackbird,killdeer, spotted sandpiper, and song <br /> sparrow. There are numerous other ponds and lakes within several miles of the site that provide similar habitat <br /> for migrating birds. <br /> Based on NDIS data, a mule deer resident population area is located within the site; however, based on what <br /> was previously described, it is unlikely for deer to enter the fencing. The Project area is also located within the <br /> geese foraging area and geese winter range. Wildlife areas that are outside of the Project area,but within a mile <br /> of Sandy Acres gravel pit pond include white pelican foraging area, geese winter concentration, geese <br /> production area, bald eagle (Haliaeetus leucocephalus) winter concentration area, great blue heron foraging <br /> area, and mule deer migration corridor. These areas are all associated with the riparian habitat of the South <br /> Platte River, located approximately 0.5 miles west of the Project area(CPW 2014a). <br /> PRESENCE AND ESTIMATED POPULATIONS OF THREATENED AND ENDANGERED SPECIES <br /> The USFWS, Mountain-Prairie Region (Region 6) lists eight federally proposed, candidate, threatened, or <br /> endangered species or subspecies with the potential to occur or be affected by the Project (USFWS 2014a). In <br /> addition, the Colorado Natural Heritage Program (CNHP) and CPW lists nine rare animal and plant that are <br /> known to occur within Adams County, Colorado (CNHP 2014, CPW 2014b). Table 1 describes these species <br /> and their potential for occurrence within the Project area. <br /> Table 2:Listed and Rare Species With the Potential to Occur or be Affected by <br /> Projects Within Ara shoe County,Colorado. <br /> lffipr <br /> Suitable habitat <br /> Burrowing Athene ST, Dry,open,treeless areas located on eastern <br /> Owl cunicularia CNHP associated with burrowing border of the pond: No effect. <br /> Rare mammals. not expected to be <br /> affected by fill. <br /> Open country,primarily <br /> Ferruginous Buteo regalis SC prairies;nests in tall trees or No suitable habitat in <br /> Hawk willows along streams or on Project area.
