Big Bend National Park, situated in a remote area of southwestern Texas along the U.S.–Mexico border, faces a growing environmental challenge. As the Rio Grande meanders through the park’s canyons and desert valleys, it has become a pathway for illegal livestock crossings.
In recent years, cattle, horses, and other livestock from Mexico have been entering the park to graze on its rich biodiversity. This has raised concerns among park officials, as the grazing not only tramples native vegetation but also disrupts archaeological and historical sites.
Despite a comprehensive management plan implemented by the National Park Service (NPS) in 2018 to address the issue, illegal grazing persists, inflicting significant damage on the ecosystem.
The area encompassing Big Bend National Park is part of a much larger conservation landscape, stretching across 3.3 million acres to include Big Bend Ranch State Park and several protected regions in Mexico, such as Cañón de Santa Elena and Maderas del Carmen. This vast area, rich in both desert and forest habitats, now faces an unusual threat from unauthorized livestock.
Animals, particularly horses, burros, and cattle, cross the river in search of food and water, inadvertently turning into agents of ecological destruction. Their presence leads to soil erosion, the trampling of flora, and even the degradation of cultural sites, including historic structures and rock art panels.
In response to these challenges, the NPS devised the Trespass Livestock Management Plan in 2018, which outlined two alternatives to manage the livestock problem.
Alternative A focused on maintaining existing control methods, which included the removal of specific animals and monitoring their impact on the park’s environment, depending on available funding.
On the other hand, Alternative B proposed a more aggressive approach, introducing helicopter-assisted control and enhanced treatment options. This strategy aimed to ensure the ongoing removal of illegal livestock on an annual basis.
However, despite these efforts, the implementation of the plan has faced challenges, leading to continued high populations of illegal livestock within the park.
In a recent letter to the NPS, Philip A. Francis, Jr., Chair of the Executive Council of the Coalition to Protect America’s National Parks, highlighted the ongoing failures of the 2018 plan. He expressed concerns regarding the inconsistent rollout of the management strategy and emphasized the urgent need for increased prioritization.
“We are writing to express our concerns about the inconsistent implementation of the 2018 Big Bend National Park (BIBE) Livestock Plan (Plan),” Francis noted, urging the park authorities to place a higher emphasis on addressing the issue.
The letter also pointed out the significant understaffing within the park’s trespass livestock intervention team. As of 2023, the team comprised only a Trespass Livestock Coordinator and a Science and Resource Management employee.
Consequently, Francis reported alarming increases in illegal livestock numbers, stating, “The density of livestock being released and rotated throughout the park is at the highest levels ever recorded by staff. This is resulting in severe resource damage and a reduced quality visitor experience, including compromising visitor safety due to motor vehicle versus livestock collisions.”
As Big Bend National Park continues to grapple with illegal livestock grazing, the future of its diverse ecosystems hangs in the balance. The park’s appeal to hikers, campers, and nature enthusiasts depends on effective management strategies to safeguard its unique environment from unauthorized grazing activities.
