Wildlife Resources Assessment Cemex "C" Pit and CKD Disposal Site Page 7 Quarry and includes rare plant and imperiled natural communities, and designated critical wildlife habitat. In addition to these professional reports, Mike Figgs was appointed in 1997 by the Boulder County Board of County Commissioners to chair the North Foothills Open Space Advisory Committee, a 22 member stakeholder group that advised Boulder County on the management of the North Foothills Open Space complex located to the west of the cement plant. During 1989 Mike personally negotiated the original conservation easement that protects riparian habitat at the Allegra Collister Nature Preserve one mile south of the Lyons Quarry. This site is now used as a long term bird banding stations supported by the Rocky Mountain Bird Observatory and Boulder County Nature Association. In 1984 he received an award from Plan Boulder County for initiating the citizen drive for Boulder County to make the original Rabbit Mountain Open Space acquisition, located 2 miles northeast of the cement plant. By means of these projects Mike has been involved in wildlife inventories, wildlife management policy and habitat protection for more than twenty years in and near the analysis area. 5.0 WILDLIFE RESOURCES S.l Wildlife Habitat Wildlife use of the landscape tends to focus on specific habitats. The plant communities and cover types discussed Section 3.3 above are equivalent to major habitat types, and are discussed below. Riparian: (St. Vrain Creek as well as irrigation ditches with trees and shrubs) essential breeding habitat for dozens of species of resident and migratory birds (particularly neotropical migrants), important habitat for mammals, reptiles and amphibians. Riparian ecosystems provide optimum shelter and food for wildlife and therefore function as movement corridors. Tame Pasture: winter range and year round range for deer, year round habitat for resident bird species, foraging habitat for migratory bird species, reptiles and many small mammals. Reclamation Sites: winter range and year round range for deer, year round habitat for resident bird species, foraging habitat for migratory bird species, reptiles and many small mammals. Wetlands: critical habitat for amphibians and small mammals, foraging habitat for deer and nesting and migratory songbirds. A uatic: critical habitat for amphibians, critical habitat for migratory waterfowl and shorebirds. Hieh Wall: this habitat is represented by remaining mine high walls in the remaining open portion of "C" Pit (Photo Point 1), and as a part of final reclamation, such as at "A" Pit (Photo Points 3-5). This habitat is equivalent to natural rock outcrops, and potentially provides habitat for bat roosts, and preferred habitat for some small mammals and reptiles. The high walls are commonly used by rock doves for perches, roosts and potential nest sites.
