Overview The Rocky Mountain Arsenal National Wildlife Refuge.
The Rocky Mountain Arsenal National Park is a 15,000-acre wildlife refuge for the restoration of native vegetation and wildlife. It is the largest urban national refuge in the country. This land has a story of transformation. Once used for manufacturing chemical agents during World War II and later for producing agricultural pesticides, the area faced significant environmental challenges due to past industrial practices. Over time, dedicated cleanup efforts by government agencies and experts helped restore the land. Today, what was once a site of heavy industry has been reborn as a national park and wildlife refuge, managed by the U.S. Fish and Wildlife Service. Visitors can now explore a landscape where nature has reclaimed its space, offering a powerful reminder of resilience and renewal.
Today, The Rocky Mountain Arsenal National Wildlife Refuge provides a safe haven for over 330 different species of animals. This includes a wide array of birds, mammals, reptiles, amphibians, and more. Keep in mind that these numbers can fluctuate over time due to seasonal migrations and ongoing conservation efforts, but the refuge remains a vital sanctuary for a remarkably diverse range of wildlife.
