Concerns Over Cottonwood Grove Destruction Amidst Border Wall Project
The environmental effects of the ongoing border wall construction have sparked significant concern, particularly due to the destruction of a historic cottonwood grove at the Arizona-Mexico border. This development comes as part of the latest efforts under the Trump administration’s border wall initiative.
Located in Lochiel, Arizona, approximately 25 miles east of Nogales, the grove has become a focal point for environmental activists. On Monday, tensions escalated as construction crews began removing the trees, leading to the arrest of a protester who tried to intervene.
A video from the scene shows a discussion between a construction worker, a Border Patrol agent, and an onlooker, with a fallen cottonwood tree trunk and heavy machinery in the background.
Erick Meza, who coordinates the borderlands program for the Sierra Club, highlighted the historical significance of the four cottonwood trees, each over a century old, situated along the border in Lochiel. According to Meza, all but one tree have been felled by construction activities, contrary to the protective measures outlined by Border Patrol.
Meza expressed frustration, stating, “And even after they were told about this letter, they didn’t want to listen. They start using some of the heavy machinery they have and just taking down the trees.”
As per a June 18 letter released by the Sierra Club, the trees were designated for removal to make way for the border wall within the Roosevelt Reservation, a 60-foot strip of federal land. The letter also mentioned the presence of environmental monitors during the removal process and coordination with federal agencies if migratory birds were affected.
“If construction activities will result in the disturbance or harm of a migratory bird, then coordination with the appropriate federal agencies will occur,” the letter states. “The contractor will also establish a buffer zone around active nests until nestlings have fledged and abandoned the nest.”
Meza lamented the lack of adherence to these measures, citing the absence of any response to videos sent to Border Patrol showing nesting activity in the trees.
In response to the incident, the Santa Cruz County Sheriff’s Office confirmed that a protester was arrested for third-degree trespassing after refusing to vacate the construction area. The individual was later released and is expected to appear in court later this week.
In late 2025, the Trump administration awarded approximately $1.4 billion to Fisher Sand and Gravel Co. The company was tasked with building 19 miles of new and secondary border wall in Arizona, as well as installing 136 miles of detection technology.
This contract is part of a larger, multibillion-dollar initiative to erect a “Smart Wall” system across Arizona and Texas, incorporating surveillance, lighting, and physical barriers. Construction is planned over vast areas of public land in Arizona, overlapping with existing sections of the 30-foot steel bollard wall established during the first Trump administration.

As of yet, neither CBP nor Fisher Sand and Gravel Co. have provided comments regarding the removal of the cottonwood trees or the stipulations in the June 18 letter.
