Along the Lower Gila River, collaboration is making a difference by reducing wildfire risk, protecting critical infrastructure, and restoring the natural beauty of the Lower Gila River corridor. Through collaboration, partners are addressing the threat of wildfire while supporting healthy native ecosystems. This sustained effort improves safety for nearby communities, protects important assets like power lines and bridges, and helps native plants and wildlife thrive. Learn how a diverse group of partners is making meaningful progress through restoration, research, and on-the-ground operations. This video shares the story of a shared commitment to protecting people, wildlife, and the Lower Gila’s future. This is the second version of the video that was originally released on March 4, 2024.

Early settlers dammed and diverted the river, disrupting natural flows and encouraging the spread of non-native species such as tamarisk (salt cedar). This invasive tree replaced native vegetation, increased wildfire and flood risks, and reduced biodiversity. To address these challenges, the Lower Gila River Collaborative was established in 2018. Its mission is to restore native habitats, reduce fire and flood hazards, and reconnect communities to the river through recreation and sustainable development. The Collaborative brings together local governments, tribes, nonprofits, and state agencies to manage approximately 46 miles of the river corridor—from Phoenix’s 91st Avenue Water Treatment Plant to the Gila Bend Dam. Pilot Restoration Efforts Early pilot projects, led by the Maricopa County Flood Control District, removed tamarisk from 40-acre test sites to study how mechanical removal affects floodplain management and habitat recovery. These efforts revealed that tamarisk’s dense growth not only restricts water flow but also increases the intensity of fires and flooding when it dies or burns. The Tamarisk Beetle and Fire Risks A biological control effort began in the early 2000s with the release of the tamarisk leaf beetle across several western states. While the beetle successfully weakened tamarisk populations, it also created large areas of dead, dry vegetation, heightening wildfire risk. Firefighters described flames exceeding 50 feet, threatening nearby communities like Buckeye, as well as critical infrastructure including bridges and water treatment plants. Restored areas are now being managed as firebreaks, with native species like willow and cottonwood reintroduced to create more fire-resistant landscapes. Flood Hazards and Agricultural Impacts In addition to fire, tamarisk infestations exacerbate flooding by trapping debris and impeding water flow. Longtime farmers along the Gila River described losing cropland and seeing valuable farmland buried under sand and river rock during flood events. Restoring natural water flow and vegetation helps protect farmland and reduce property damage, while also improving groundwater recharge and habitat quality. Funding and Long-Term Management The Collaborative has secured $15 million from the Arizona state legislature and governor’s office to expand restoration activities, focusing on tamarisk removal, native replanting, and long-term monitoring. Land managers emphasized that restoration requires ongoing maintenance, adaptive management, and community participation to sustain results. Vision for the Future The long-term goal is to revive the river’s natural functions, restore traditional plant species important to Indigenous communities—such as willow used in basketry—and ensure the river remains viable for future generations. Community members envision a river that supports farming, wildlife, recreation, and cultural continuity. In closing, the Collaborative emphasized that restoring the Lower Gila River is not a one-time effort but a shared, generational commitment to resilience, ecological health, and community connection.
