Rocky Mountain Arsenal National Wildlife Refuge

Rocky Mountain Arsenal National Wildlife Refuge (NWR), located 10 minutes from downtown Denver, is nearly 17,000 acres, making it one of the largest urban wildlife refuges in the United States. It consists of open lakes, wetlands, prairie grasslands, and woodlands.

Due to its proximity to Denver, one of the Refuge's primary goals is to provide environmental education programs for urban school children. Each year, thousands of visitors come to the Refuge to appreciate its wildlife, view the scenic habitat, and learn about native prairie species. The Arsenal has been called "a significant habitat island for wildlife" and "a place to renew the relationship with nature." Popular activities include interpretative programs, environmental education, fishing, wildlife observation, and photography.

Management Activities
One of the primary objectives of the Refuge is to restore and mange the land to provide quality wildlife habitat. Previous land uses, including farming and military and industrial operations, resulted in the loss of native species, which made the establishment of exotic plants possible. Approximately 8,000 acres of disturbed land is currently being restored with native prairie grasses, wildflowers, and shrubs.

Weeds are the major obstacle to establishing native grasses. An integrated pest management program incorporates a variety of mechanical, biological, and chemical controls. Prescribed burning and mowing are additional techniques used to manage the habitats.
