Three cottonwood trees standing for more than a century at the U.S.-Mexico border in Lochiel, Arizona, were removed July 27 to make way for border barrier construction, according to local activists. The Department of Homeland Security proceeded with the removal despite objections from environmental groups and local residents who'd gathered at the site.
The trees fell within the Roosevelt Reservation, a 60-foot-wide federal stretch established in the early 1900s to combat smuggling along parts of the border. U.S. Border Patrol official Michelle "Shelly" Barnes wrote in a June letter that the trees "cannot be relocated" and "will be removed in order to construct the border barrier."
Federal Authority and Local Opposition
At least one person was arrested in connection with protests over the tree removal, the Santa Cruz County Sheriff's Office confirmed. The individual faced trespassing charges. A fourth cottonwood remained standing at the site, surrounded by protesters attempting to prevent its destruction, said Erick Meza, a border program coordinator for the Sierra Club in Arizona.
The Sierra Club shared photos of bulldozers taking down the massive trees, which can grow to 100 feet tall and nearly 50 feet wide. Meza said the trees were removed "without environmental monitors" and despite legally protected bird species nesting in them. Department of Homeland Security officials didn't respond to USA TODAY requests for comment.
The Ecosystem Question
The cottonwoods sat at the center of an area the U.S. Fish and Wildlife Service listed as among the only jaguar ranges in the country. Other animals in the region included antelope, cougar and "many birds unique to the prairie," according to Arizona state park authorities. The trees' branches extended across the border in both directions. "The trees were so big that their branches were reaching into Mexico, and branches from the trees in Mexico were reaching into the United States, creating a connected ecosystem," Meza said.
Lochiel resident Laurie Butler told local news outlet AZPM in June that the cluster had served as a gathering place for generations. "It's kind of the heart of that little valley," Butler said when it became clear the cottonwoods were in the border wall's path.
Among the birds in the area was Cassin's kingbird, a species local activists said was nesting in the trees at the time of their removal. The tyrant flycatcher bird is protected under federal law, though it isn't endangered. The removal came after Border Patrol assured in its letter that the agency would "establish a buffer zone around active nests."
Broader Border Tensions
The dispute over the Arizona cottonwoods represents the latest friction between border security construction and environmental concerns. President Donald Trump's administration faced pushback from border communities and environmentalists as the barrier moved through remote yet ecologically distinct areas. The construction sparked outrage even in deeply Republican Texas.
The Sierra Club, an environmental organization formed by early American naturalist John Muir around the turn of the century, has grown into perhaps the nation's preeminent conservationist organization. It fought to keep the Grand Canyon from being flooded in the 1960s and protested outside President Barack Obama's White House in 2011 to prevent construction of the Keystone XL Pipeline.
Meza described the situation as unique. "This is a very unique situation because there is no other place in the entire border," he said.
Why This Matters:
The removal highlights the ongoing tension between federal border security authority and local environmental concerns. The Roosevelt Reservation gives the federal government clear legal standing to construct barriers on its designated land, a power established more than a century ago specifically for border enforcement purposes. Yet the incident demonstrates how infrastructure projects intersect with protected species regulations and community interests. The dispute raises questions about whether federal agencies can balance security construction with environmental compliance, particularly regarding protected species like Cassin's kingbird. It also shows how border security remains contentious even in areas where the federal government holds explicit jurisdiction, suggesting future construction will continue facing similar challenges from activists and residents who prioritize ecological preservation over barrier expansion.
