The Colorado Front Range National Wildlife Refuge Complex consists of Rocky Flats NWR, Two Ponds NWR, and Rocky Mountain Arsenal NWR. A National Wildlife Refuge Complex is an administrative grouping of two or more refuges, wildlife management areas or other refuge conservation areas that are primarily managed from a central office location. Refuges are grouped into a complex structure because they occur in a similar ecological region, such as a watershed or specific habitat type, and have a related purpose and management needs. Rocky Flats National Wildlife Refuge is a 5,237-acre refuge in Golden, Colorado, and 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
