Alamosa National Wildlife Refuge

The Alamosa National Wildlife Refuge covers 11,169 acres of high desert uplands and riparian wetlands in the San Luis Valley. It’s situated in a high-elevation, alpine basin in south-central Colorado.

Residing at 7,800 feet above sea level, the valley covers more than 100 miles north to south and 50 miles east to west. Although mostly flat, some of the most majestic mountain ranges in the Rockies surrounded it. The Sangre de Cristo lies the east, to the west are the San Juan Mountains and the Sawatch sit north. Thanks to the snow capped peaks, the valley is able to sustain wildlife through surface ponds and rivers, and a large underground aquifer.

The Rio Grande River flows into the reservoir, creating a mixed landscape of wetlands, ponds, dry uplands, and riparian corridors. Plants are all drought resistant types, including rabbitbrush and greasewood.

The refuge was founded to protect the food, cover and breeding grounds for local wildlife and transient birds. It accomplishes that goal for more than 200 species of birds and other animals. Twice per year, around mid-March and mid-October, ten’s of thousands of Sandhill Cranes migrate through the San Luis Valley.
