Bulldozers have entered Big Bend National Park in Texas as part of a $1.7 billion border security project, sparking concerns over the impact on the park's protected ecosystem.

Bulldozers have arrived at Big Bend National Park in southwest Texas to begin construction on border security infrastructure. The project is part of President Donald Trump’s plan to implement $1.7 billion in border security measures. Government contractors have been observed clearing native vegetation along the Rio Grande, with plans in place to construct vehicle barriers and patrol roads throughout the park.

Environmental Impact Concerns

The Center for Biological Diversity stated that the planned construction, which includes vehicle barriers and patrol roads, will require dynamite blasting that could damage the local ecosystem. Big Bend National Park is home to over 1,200 plant species and thousands of animal species, including more types of birds, bats, butterflies, ants, scorpions, and cacti than any other U.S. national park. In June, the Department of Homeland Security waived dozens of environmental laws, a move that may have facilitated the start of construction in an area that accounted for 1.3% of total border apprehensions in 2025.

Advocacy and Public Response

Organizations and citizens are working to oppose the construction plans. The Big Bend Protection Alliance is accepting donations to support monitoring and public awareness efforts. Additionally, the National Parks Conservation Association has launched a "Stop Bulldozing in Big Bend" petition, encouraging the public to contact members of Congress and Texas Governor Greg Abbott.
