Big Bend Landowners Sue to Block Border Wall Through Texas Ranchland

A coalition of landowners, ranchers and business owners in the Big Bend region of Texas, joined by the nonprofit Conserve Big Bend, has filed a federal lawsuit in Washington, DC, seeking to stop the Trump administration's plans to build a wall and other border infrastructure through the remote stretch of the state.

The suit, filed on behalf of six landowners and backed by dozens more along the border, targets a $46 billion effort to line roughly 2,000 miles of the southern border with 30-foot steel bollard walls, vehicle barriers and surveillance technology. In Texas, the push has drawn bipartisan opposition from sheriffs, elected officials, tour guides, environmental groups and property owners, and has already generated multiple legal challenges.

At the heart of the case is the Department of Homeland Security's designation of the Big Bend as an area of "high illegal entry," which allows the agency to waive environmental, archaeological and wildlife protections. The plaintiffs argue that designation is factually and legally unsound. They point to Customs and Border Protection statistics showing that while Big Bend accounts for about 500 miles of border — roughly a quarter of the total U.S.-Mexico boundary — the region recorded only about 1% of arrests.

"Declaring over 500 miles of steep cliffs and perilous desert, an area of high illegal entry, is not just detached from reality. Under federal law, it is arbitrary, capricious, and unlawful," said Clara Benson, a board member of Conserve Big Bend, speaking outside the Presidio County courthouse in Marfa.

Benson said the government is pressing landowners to sign irreversible three-year agreements granting access for heavy construction, 30-foot steel bollard walls and steel road barriers, with the threat of eminent domain hanging over more than 400 property owners. She warned that a wall in such terrain would sever ranches, trigger catastrophic flash flooding, cut communities off from the Rio Grande and permanently scar the landscape.

Laura Allen, a two-time Trump voter and former county judge whose family ranch would be bisected by the wall, said the border is already secure and urged the administration to halt the project. "This is not a partisan issue," she said, standing alongside a landowner she identified as a proud Democrat. She noted that illegal border arrests have fallen further since Trump returned to office.

Lico Miller, another landowner, framed the dispute as a broader property-rights question. "If they can take our land along the river today, they can come for yours tomorrow," he said, warning that the precedent could extend to power corridors, data centers or other projects. "Using eminent domain to strip multi-generational landowners of their land, their water, their livelihood is fundamentally wrong."

Joaquin Pena, whose family has farmed in the region for generations, said the government's rationale for taking half of his farmland made no sense to him. "This is God's country, so it's time for us to start doing the right thing and protecting it," he said.

David Keller, an archaeologist and historian specializing in the Big Bend, said landowner resistance has already slowed the project. Access agreements have been refused, survey and construction schedules have fallen months behind, and contractors have been sent home, he said. "They were woefully unprepared for the hornet's nest they stirred up because they had no idea how much we love this place."

The lawsuit is the latest effort to slow or stop the administration's plans in Texas. The most vocal opposition has centered on Big Bend National Park, a remote and rugged area where the Rio Grande separates the two countries and whose limestone canyons and dark night skies draw visitors from around the world. The government has said in court hearings that no final decisions have been made about what will be built in the park, though plans made public so far have included a new road and detection technology.
