General Information

  • Rocky Flats National Wildlife Refuge

    Lindsay Ranch

    The Rocky Flats National Wildlife Refuge was established in 2007 and is managed by the U.S. Fish and Wildlife Service. This 5,000-acre Refuge has striking vistas of the Front Range of the Rocky Mountains and rolling prairie grasslands, woodlands and wetlands. It is home to 239 migratory and resident wildlife species, including prairie falcons, deer, elk, coyotes, songbirds, and the federally threatened Preble’s meadow jumping mouse. Large areas of the Refuge have remained relatively undisturbed for the last 30 to 50 years resulting in diverse habitat and wildlife. A portion of the Refuge contains rare xeric tallgrass prairie, providing habitat for a variety of wildlife and serving as an important natural and conservation resource.
