The environmental impact of border walls, explained.
Read more about the border wall’s effect on wildlife here.
When we talk about the consequences of the proposed wall at the border of the US and Mexico, we usually think in terms of people. But along the political divide are rich pockets of biodiversity, with dwindling populations of species that rely on the ability to move back and forth across the border.
Under the 2005 REAL ID act, the Department of Homeland Security doesn’t have to comply with various environmental laws that might otherwise slow or halt construction in a sensitive area. Laws like the Endangered Species Act, the Clean Water Act, the National Environmental Policy Act or the Migratory Bird Treaty Act — none of those apply to border wall construction.
Several parcels of land, including the National Butterfly Center, a state park, and other areas in the federal wildlife refuge system — are still threatened by wall construction. It could still be years before construction starts in some of these areas — but there’s still a lot we don’t know about the full impact of barriers on biodiversity.
Scientists warn that proposed US-Mexico border wall threatens biodiversity, conservation
July 24, 2018
Amidst increased tensions over the US-Mexico border, a multinational group of over 2500 scientists have endorsed an article cautioning that a hardened barrier may produce devastating ecological effects while hampering binational conservation efforts. In the BioScience Viewpoint, a group led by Robert Peters, William J. Ripple, and Jennifer R. B. Miller call attention to ecological disturbances that could affect hundreds of terrestrial and aquatic species, notably including the Mexican gray wolf and Sonoran pronghorn.
The authors argue that the border wall will harm wildlife populations by fragmenting, degrading, and eliminating existing habitat, as well as by blocking species migration. “Our analysis shows that the border bisects the geographic ranges of 1506 native terrestrial and freshwater animal (n = 1077) and plant (n = 429) species”, say the authors, noting that the number includes 62 species already listed as Critically Endangered, Endangered, or Vulnerable by the International Union for Conservation of Nature.
Further, the authors express concern that as a result of the 2005 Real ID Act, construction could proceed “without the necessary depth of environmental impact analysis, development of less-damaging alternative strategies, postconstruction environmental monitoring, mitigation, public input, and pursuit of legal remedies.” Compounding the issue of forgone legal protections, Peters and colleagues warn that a border wall could threaten ongoing research and conservation programs, including those in binational habitat corridors and the 18% of borderlands that contain environmentally protected lands.
To mitigate the effects of the proposed wall, the authors make several urgent recommendations to the United States Congress and Department of Homeland Security; these include following existing environmental laws, taking action to mitigate ecological harm, and forgoing physical barriers in particularly sensitive areas. The article` also calls for the government to encourage scientific research in the borderlands, to inform and assist environmental evaluation and mitigation efforts. The authors conclude that “national security can and must be pursued with an approach that preserves our natural heritage.”
TRUMP AGAIN THREATENS GOVERNMENT SHUTDOWN President Donald Trump has threatened to shut down the federal government ahead of the midterm elections if Democrats do not agree to fund his wall on the U.S.-Mexico border. The deadline to agree to fresh funding for the government is Sept. 30. He tweeted in 2017 that maybe the country needed a “good shutdown” over wall funding, but backed down. [HuffPost]

Biodiversity and ecosystem service losses driven by land-use change are expected to intensify as a growing and more affluent global population requires more agricultural and forestry products, and teleconnections in the global economy lead to increasing remote environmental responsibility. By combining global biophysical and economic models, we show that, between the years 2000 and 2011, overall population and economic growth resulted in increasing total impacts on bird diversity and carbon sequestration globally, despite a reduction of land-use impacts per unit of gross domestic product (GDP): here.
