B-30 <br /> Keenesburg Project RETTEW Project No. 114782000 <br /> Colorado Sand Company LLC April 2019 <br /> Provisions) and Article 2 (Nongame and Endangered Species Conservation) of the Colorado Revised <br /> Statutes, "...it is unlawful for any person to take, possess, transport, export, process, sell or offer for sale <br /> or ship and for any common or contract carrier to knowingly transport or receive for shipment any species <br /> or subspecies of wildlife appearing on the list of wildlife indigenous to this state determined to be <br /> endangered or threatened within the state." CPW also maintains a list of state special concern species; <br /> however,these species are not protected under state law. <br /> 3.2 Desktop Assessment <br /> 3.2.1 Habitat <br /> The project area consists of grasslands habitat with gently rolling topography. Vegetation is composed of <br /> various grasses, yucca, and sand sagebrush. Trees are largely absent within the project area. Elevations <br /> across the site range from 4,950 —4,600 feet and mean annual precipitation ranges from 10 -18 inches <br /> (Armstrong, 1992). Soils contain a high percentage of sand and are mostly well-drained. The majority of <br /> the project area is a homogenous landscape,although one drainage(Ennis Draw) runs from south to north <br /> in the western half of the site.Areas of ponded water, dense vegetation and adjacent wetland habitat can <br /> be found within this drainage. <br /> 3.2.2 Federal Species <br /> A desktop study was conducted using the U.S. Fish and Wildlife (USFWS) Information, Planning, and <br /> Conservation (IPaC)System to identify federally listed species potentially occurring within the project area <br /> or that may be affected by the proposed project (IPaC, USFWS 2018). Nine federally listed threatened, <br /> endangered or candidate species were identified (Appendix D).Table 3.1 evaluates the potential for each <br /> of the species to occur within the project area. <br /> Table 3.1 - Federally Listed Species <br /> Potential <br /> Common Name Scientific Name Status Habitat Occurrence <br /> within Site' <br /> Birds <br /> Least Tern' Sterna antillorum Endangered Sandbars along rivers, lake Not Likely <br /> shorelines, only known to <br /> occur in southern <br /> Colorado <br /> Mexican Spotted Owl Strix occidentalis Threatened Old growth forests Not Likely <br /> lucida <br /> Piping Plover' Charadrius Threatened Sand/gravel beaches Not Likely <br /> melodus adjacent to alkali wetlands <br /> and sandbars of major <br /> rivers <br /> Whooping Crane' Grus americana Endangered Wetlands, wet meadows, Not Likely(last <br /> areas around rivers and wild bird in CO <br /> agricultural fields died in 2002) <br /> Table continues on next page <br /> 4 <br /> Keenesburg Project_Limited Impact 110 Application_May 24,2019 <br />
