Appendix-7 Keenesburg Project RETTEW Project No.114 782 000 Colorado Sand Company LLC April26,2019 3.1.2 State Colorado Parks and Wil life (CPW) maintains a list of threatened and endangered species in the state of Colorado.Perthe regulations contained in Title 33 Parks and Wildlife—Wildlife Article 1(Wildlife—General Provisions) and Article 2 (Nongame and Endangered Species Conservation) of the Colorado Revised Statutes, "...it is unlawf dfor any person to take, possess, transport, export, process, sell or offer for sale or ship and for any common or contract carrier to knowingly transport or receive for shipment any species or subspecies of wildli a appearing on the list of wildlife indigenous to this state determined to be endangered or threatened within the state." CPW also maintains a list of state special concern species; however,these species are not protected under state law. 3.2 Desktop Assessment 3.2.1 Habitat The project area consists of grasslands habitat with gently rolling topography. Vegetation is composed of various grasses, yucca, and sand sagebrush. Trees are largely absent within the project area with the exception of a grove of Russian olives growing in the southeast quarter of Section 12. This grove of trees provides scrub-shrub habitat within Ennis Draw. Elevations across the site range from 4,950—4, 600 feet above mean sea level,and mean annual precipitation ranges from 10-18 inches (Armstrong, 1992). Soils contain a high percenta a of sand and are mostly well-drained. Most of the project area is a homogenous landscape consisting of razed upland grasslands with patches of sagebrush. However, habitat is distinctly different in portions of the drainage (Ennis Draw) running through the project area. Areas of ponded water, dense vegetation and adjacent wetland habitat can be found within this drainage. 3.2.2 Federal Species A desktop review was clone using the USFWS Information, Planning, and Conservation (IPaC) System to identify federally listed species potentially occurring within the project area or that may be affected by the proposed project ( PaC, USFWS 2018). Nine federally listed threatened, endangered or candidate species were identified (Appendix D). Table 3.1 evaluates the potential for each of the species to occur within the project area.
