Protesters Occupy Ancient Cottonwood Tree to Block Trump-Era Border Wall Expansion

Core Event: Tree Sit Halts Construction Near Lochiel, Arizona
Around 22 miles south of Patagonia, Arizona, a cottonwood tree estimated to be at least 200 years old became the focal point of a direct-action protest. After a crew felled three neighboring trees on July 27, activists climbed the remaining tree on July 29 and installed a platform in its branches. They maintain a continuous presence, arguing that as long as a person occupies the tree it cannot be cut down. The tree sits directly in the planned path of a “double wall” that would add 30-foot steel bollards and a new access road through the San Rafael Valley and the Tohono O’odham reservation.
Background & Context: Renewed Border Barrier Push
Since the Trump administration revived the border-wall program, the Department of Homeland Security (DHS) has dispatched contractors to remote sections of the Arizona-Mexico border, invoking waivers of environmental statutes. The One Big Beautiful Bill Act, passed in 2025, allocated an additional $46.5 billion for wall completion. In Arizona’s San Rafael Valley, DHS plans a “double wall” that would replace an existing fence with new steel bollards and a parallel barrier, placing the cottonwood tree in the line of the second wall. In Texas’s Big Bend National Park, Customs and Border Protection (CBP) proposes a “smart wall” of sensors, cameras, and a new patrol road.
Data & Statistics
Official Statements & Responses
CBP chief Rodney Scott described the work as limited infrastructure: “CBP is building one new access road, improving existing roads, installing detection technology, and placing vehicle barriers in limited, strategic locations.” He announced a pause on all construction in Big Bend National Park on August 17, citing a personal on-the-ground evaluation. DHS officials have repeatedly asserted that no 30-foot wall is being erected in the national parks, characterizing current activity as “survey and design work” rather than wall construction.
Local Opposition & On-the-Ground Reports
Activists have established an encampment on private land near the tree, using a pulley system to supply food and water to the sitter. Community organizer “Henry” (pseudonym) reported that a DHS helicopter flew “dangerously close” to the tree on August 10. River guide Billy Miller, a 22-year resident, described contractors beginning “grubbing and pioneering” on Mariscal Mountain without the promised 30-day notice. Local businesses, such as the Starlight Theatre, have refused to serve wall construction crews. Residents argue the wall is a waste of funds that could instead support additional agents, infrared cameras, motion sensors, and drones.
Conflicting Reports & Gaps
CBP officials maintain that the project does not involve a traditional wall in the park, while activists contend that the planned bollards and access roads constitute a de-facto barrier that will damage ecosystems and restrict public access. No independent verification of the exact construction footprint has been provided, and the federal judge’s March dismissal of a related lawsuit leaves the legal status of the environmental waivers unclear.
What’s Next
CBP has indicated that the National Park Service will decide whether the newly built access roads will be opened to the public. The pause announced on August 17 suggests further evaluation before any additional construction proceeds. Activists plan to maintain the tree sit for as long as the barrier remains threatened, and local opposition groups continue to organize protests and business boycotts.
