the South Platte River to the southwest and northeast of the project site. These features are <br /> depicted in Figure 1. <br /> The bald eagle nest west of the project site depicted on the COGCC mapping was not found <br /> during the on-site investigation. Another bald eagle nest, not depicted on the COGCC <br /> mapping,was identified immediately outside the project site,near the northwest boundary. <br /> An active great horned owl nest was also located within the project site immediately <br /> adjacent to Colorado Highway 60 north of Weld County Road 42. <br /> During the on-site investigation, the following wildlife species were observed; bald eagle, <br /> Canada geese, great horned owl, northern harrier, red-tail hawk, red-winged blackbirds, <br /> and black-tailed prairie dogs. <br /> Seasonal Use <br /> The mammal species that potentially occur on-site are expected to be year-round residents <br /> or users of the site. The carnivore and ungulate species are not restricted to this site and <br /> tend to have relatively large home ranges (up to several square miles). The majority of <br /> rodent and insectivore species can be expected to reside on-site throughout the year,though <br /> many may hibernate during the cold months. Avian species may be year-round,temporary <br /> migrants, or summer residents of the site. Year-round residents would include the <br /> waterfowl, raptors, gallinaceous birds, pigeons, owls, and woodpeckers. The majority of <br /> the shorebirds and passerines would use the site during the spring, summer, and fall for <br /> feeding or resting during migration. Amphibian and reptile species of the site are year- <br /> round residents. <br /> Threatened and Endangered Species and Critical Habitat <br /> Potential habitat for the Preble's meadow jumping mouse was evaluated based on results <br /> of a search of potentially occurring threatened or endangered species on the U.S. Fish and <br /> Wildlife Service web site for Weld County. <br /> Additionally, bald eagle (Haliaeetus leucocephalus) nest locations and winter night roost <br /> locales were evaluated from the Colorado Oil and Gas Conservation Commission <br /> (COGCC)web site map of sensitive wildlife habitat and restricted surface occupancy areas <br /> for protected wildlife species. <br /> Additional protected eagle and owl nests were located within or adjacent to the project site <br /> and are discussed below. <br /> Preble's meadow jumping mouse <br /> Potential habitat exists for the Preble's meadow jumping mouse within the project site along <br /> the South Platte River and within the adjacent riparian corridor, marsh, and wetland areas. <br /> Exhibit H Page 2 <br />
