Our Work Protecting Habitat Along the Colorado River With the Cocopah Indians

Colorado River at Diamond Creek

National Wildlife Federation is partnered with the Cocopah Indian Tribe to accomplish the cultural and environmental preservation of the 23-mile Lower Colorado River Limitrophe, including 12 miles within the Cocopah Reservation.

"Limitrophe" means "bordering," and refers to the land alongside America's majestic Colorado River. This particular stretch of land sustains the largest proportion of native cottonwood, willow and mesquite species on the entire river, providing more than twice as much native habitat than any other stretch of the Lower Colorado River.

Wildlife of the Lower Colorado River

More than 120 species of waterfowl, wetland, and neotropical birds use habitats along the Limitrophe riparian corridor for feeding and resting refuge. Migratory birds use this area as a stopover along the Pacific Flyway, connecting their wintering habitats in Mexico and Central America and their breeding grounds in the northern U.S. and Canada.

In addition, the habitat supports threatened and endangered species such as the Yuma clapper rail, Southwestern willow flycatcher, Bell’s Vireo and Yellow-billed cuckoo (under listing consideration).

Restoration and protection of the Limitrophe will help complete a link between protected areas along the Lower Colorado, treating the river as a complete ecosystem rather than as fragmented areas.
