How Trump’s border wall would disrupt nature

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.

Protected habitats near US borders

December 4, 2019

Summary: The clustering of protected habitats in the Americas near international borders makes many iconic, wide-ranging animals physically dependent on good relations between neighboring countries and wildlife-friendly borders.

Resembling an overgrown house cat with black-tipped ears and a stubby tail, the Canada lynx, a native of North America, teeters on the brink of extinction in the U.S. The few lynx that now roam parts of Washington and the mountainous Northwest survive largely because of a network of protected landscapes that crosses the U.S.-Canada border.

Washington State University environmental researchers believe this transboundary landscape provides not only essential habitat for the wild cats but likely also vital connections with larger lynx populations in Canada.

Wildlife cameras set by WSU researchers recently photographed lynx in the Kettle Mountains of far northeast Washington, close to the Canadian border, and more big cats have been spotted in Glacier National Park near the Montana-Canada line.

Lynx, like their forest-dwelling neighbor the grizzly bear, require many miles of connected, undeveloped terrain to survive. According to new research led by Daniel Thornton, assistant professor in WSU’s School of the Environment, such terrain occurs most frequently throughout the Americas near international borders.

This clustering of protected habitats, including national parks and conservation areas, makes many iconic, wide-ranging animals — lynx, grizzlies, jaguars, tapirs and scarlet macaws among them — physically dependent on good relations between neighboring countries and wildlife-friendly borders.

“Because protected areas are more common near international boundaries, cooperation across borders will be key to maintaining large, connected, resilient protected areas for biodiversity conservation,” Thornton said. “And because border regions are so important in this regard, anything that negatively impacts transboundary cooperation between countries or the ability of animals to move across borders — such as increased security and border structures — could be very problematic for species conservation.”

Cross-border cooperation needed to mitigate climate change, other threats

In addition to politically charged border security measures, climate change and other large-scale landscape alterations pose serious threats to wildlife and habitat preservation throughout the Americas.

Writing in Ecological Applications, Thornton and his research collaborators at the University of Florida and Trent University in Ontario, Canada, said their study results indicate “efforts to conserve species and mitigate effects of long-term stressors, like climate change, will be most successful when planning includes neighboring countries.”

The scientists examined the distribution, connectivity, and integrity of protected areas near the borders of 23 countries across North, South and Central America. They found clustering of these primary habitat areas extending approximately 78 miles from the borderlines.

Connectivity of protected areas is especially important for animals to be able to adjust to habitat loss and fragmentation or to shift their ranges as climate changes, the researchers said. Maintaining these landscape networks will grow increasingly critical where forest depletion is taking a toll.

For example, a cross-boundary approach to managing protected areas could be especially beneficial in the highly-threatened Dry/Wet Chaco ecoregion bordering Argentina, Paraguay and Bolivia. Rapid deforestation there is dividing habitats, causing negative impacts on numerous species.

Although international conservation efforts are relatively rare in the Americas, transboundary protected areas are expanding globally, leading to more integrated and large-scale conservation projects among neighboring countries, the researchers said. They noted additional benefits from these projects include promoting climate change resilience, sustainable development across borders, cooperative resource management and peace.

TRUMP VACATION PUSHES TAXPAYER GOLF TAB ABOVE $118 MILLION  President Donald Trump has pushed his taxpayer-funded golf tab past $118 million on his 26th visit to Mar-a-Lago, his for-profit resort in Palm Beach, Florida. The new total is the equivalent of 296 years of the $400,000 presidential salary that his supporters often boast that he is not taking. [HuffPost]
