2018 Biological Resources Inventory Report <br /> an active nest as any nest that is"frequented or occupied by a raptor during the breeding season or <br /> which has been active in any of the five previous breeding seasons" (CPW 2008). Biologists also <br /> documented suitable habitat and sightings of individual bird species protected by the MBTA in the Project <br /> area. <br /> 2.1.2.4 Noxious Weed Inventory <br /> An informal survey for state listed noxious weeds was conducted incidentally during the general wildlife <br /> and vegetation assessment. This effort was not intended to be, and should not be considered, an <br /> extensive survey of the entire Project area. <br /> 2.2 Biological Resources Inventory Results and Discussion <br /> The following sections describe the results of the biological resources assessment completed for the <br /> Project area. <br /> 2.2.1 Desktop Results <br /> 2.2.1.1 Ecoregional Setting <br /> The Project is completely situated in the High Plains Level III Ecoregion. The High Plains Ecoregion <br /> includes four Level IV ecoregions. The Project area lies within the Flat to Rolling Plains (25d) Level IV <br /> ecoregion (Chapman et al. 2001). This ecoregion is characterized by moderate topological relief, silty and <br /> sandy soils, shortgrass prairie vegetation, and intermittent streams with few perennial streams. This <br /> ecoregion is known to have small scattered depressional"playa"wetlands and dense oil and gas <br /> production. Elevation in the Project area is between 4,900 and 5,000 feet above sea level. <br /> 2.2.1.2 General Wildlife <br /> Table 2 lists the species identified by CPW as potentially occurring in the Project area (CPW 2016b). The <br /> list includes birds and mammals. Table 2 also lists the season each species is expected to occur in the <br /> Project area.With the exception of the White Pelican, all of the species in Table 2 are expected to occur <br /> in the Project area year-round. The White Pelican is expected in the Project area only during migration in <br /> the spring and fall months. <br /> Table 2: <br /> USFWS IPaNdentified Migratory Birds Likely to Occur in the Project Area <br /> Common Name Sclentlflc Name <br /> Bald Eagle Haliaeetus leucocephalus <br /> Black-tailed Prairie Dog Cynomys ludovicianus <br /> Goose Branta spp. <br /> Great Blue Heron Ardea herodias <br /> White Pelican Pelecanus erythrorhynchos <br /> Mule Deer Odocoileus hemionus <br /> Preble's Meadow Jumping Mouse Zap us hudsonius preblei <br /> White-tailed deer Odocoileus virginianus <br /> Wild turkey Meleagris spp. <br /> Tucson South Sand and Gravel Mine—Brighton,Colorado 7 <br />
