About Us

Bosque del Apache National Wildlife Refuge, located in San Antonio, Socorro County, New Mexico, is one of over 560 units within the National Wildlife Refuge System. Situated between the Chupadera Mountains to the west and the San Pascual Mountains to the east, the 57,331 acre Bosque del Apache was established in 1939 to provide a critical stopover site for migrating waterfowl. The refuge is well known for the tens of thousands of cranes, geese, and ducks who winter here each year. Over 30,000 acres of Bosque del Apache are designated wilderness.  

The Rio Grande may seem tame now, but for thousands of years it was a wild and unpredictable river. Every spring, melting snow from the mountains filled the river with water until it overflowed its banks – flooding the land around it. 

In the summer, heavy rains swelled the river even more. At times, the overflowing water was so powerful that the entire path of the river changed, forming new ponds and marshes in the old riverbed. In these fertile river floodplains, all kinds of lush vegetation grew – providing plentiful food sources for wildlife. Majestic birds like sandhill cranes migrated here to spend the winter feasting on nutritious grasses like chufa and millet while other animals thrived amid the cottonwood forests and shrublands. 

The big river attracted humans too. More than 700 years ago, Piro Indians built settlements of mud and stone houses along the river. They hunted and gathered food along the riverbanks, and they learned to farm the bottomlands. 

In the late 16th century, Spanish colonists arrived following the river northward. Their horses, wagons, cattle, and sheep trampled a rutted, dusty road. As more people moved in, they created ranches, farms, and towns that replaced the Piro Indians and their pueblos. 

The new settlers started to change the Rio Grande. A river that overflowed and dug new routes every season was seen as a problem – especially if your house got flooded or your crops washed away. So, people started building dams and irrigation ditches to manage the flow of the river and divert water for crops, livestock, and homes. Taming the wild Rio Grande was great for people – but not great for wildlife. The once-grand river shrank to a shallow stream. 

Without a flooding river, the floodplain marshes dried up. Chufa, millet, and other plants that grew in the wetlands started to disappear. When their food supply disappeared, the region’s wildlife – especially its migratory birds – started to disappear too. 

Yet, many people thought the wildlife and habitats along this portion of the river were worth preserving. In the 1930s, the Civilian Conservation Corps began working to restore the floodplains in the Bosque del Apache area as wildlife habitat. In 1939, President Franklin Delano Roosevelt established Bosque del Apache National Wildlife Refuge as part of a national system of lands dedicated to wildlife protection. 

Today, our staff manages water to create wetlands like when the river ran wild. These seasonal wetlands re-create the types of habitats that both year-round and migratory wildlife need to thrive. Using gates and ditches, water is moved from the river through fields, marshes, and ponds, and then back to the river to mimic natural flooding cycles. 

Once again, the Rio Grande and its wetlands provide food and homes for some of America’s most spectacular wildlife, as well as places where thousands of people can observe and enjoy the natural world. 

Wilderness Area

Bosque del Apache Wilderness

Designated in 1975

30,427 acres

The Wilderness Act of 1964 created the National Wilderness Preservation System "in order to assure that an increasing population, accompanied by expanding settlement and growing mechanization, does not occupy and modify all areas in the United States, and its possession, leaving no lands designated for preservation and protection in their natural condition..."

Our Mission

The mission of the National Wildlife Refuge System is to administer a national network of lands and waters for the conservation, management and, where appropriate, restoration of the fish, wildlife and plant resources and their habitats within the United States for the benefit of present and future generations of Americans. 

Our Purpose

Every national wildlife refuge national wildlife refuge
A national wildlife refuge is typically a contiguous area of land and water managed by the U.S. Fish and Wildlife Service  for the conservation and, where appropriate, restoration of fish, wildlife and plant resources and their habitats for the benefit of present and future generations of Americans.

was created for a special purpose. Some were created to protect migratory birds, others to protect threatened or endangered species or unique habitats, while others fulfill another special purpose. Refuges are special places where wildlife comes first. All activities allowed on refuges must be evaluated to make sure each activity will not conflict with the reason the refuge was founded. 

As a community partner and natural resource leader, Bosque del Apache National Wildlife Refuge enhances and protects the quality of life found in central New Mexico along the Rio Grande. As part of a network of protected lands, the refuge restores and helps sustain the ecological integrity of the Middle Rio Grande floodplain and the northern Chihuahuan Desert.  

A diverse team of employees and volunteers implements inclusive management practices that foster productive relationships with local communities, government agencies, our Friends Group and other non-government organizations, visitors, researchers, neighboring landowners, educational institutions and others to promote resource health, to respond to the concerns of the public and to perpetuate an enduring wildlife legacy for future generations of Americans.

Our History

November 22, 1939 - The refuge was officially established by Executive Order 8289 to provide refuge and breeding grounds for migratory birds.  

1941 and 1951  - Additional acreage, 3044 acres and 963 acres respectively (previously inholdings), were added to the refuge.  

2008 - a 140-acre parcel on Chupadera Peak was donated to the U.S. Fish and Wildlife Service bringing the total acreage of fee title lands (lands owned by the government) on Bosque del Apache National Wildlife Refuge to 57,331.
