Although it is now a mostly dusty, dry expanse, the delta can be brought back to life. Restoration efforts and periodic river flows offer tremendous potential for renewal. © Sonoran Institute

Enhanced riparian and marsh habitat will support 380 bird species, including more than 200,000 migratory water birds that rely on the delta. © Jackie Hall/TNC

For locals in the region, restoration work is already adding economic benefits by employing residents. Future projects offer a chance to have a resurgence in culture, tradition and local job opportunities through increased hunting, fishing and tourism. © Jackie Hall/TNC
