Work on border walls, fences and related infrastructure, such as roads, fragments habitat, erodes soil, changes fire regimes and alters hydrological processes by causing floods, for example. The potential for ecosystem damage was highlighted more than a decade ago, when the U.S. Congress passed the Real ID Act.24 Jul 2018
How would a border wall affect wildlife?
Short-term and long-term consequences of a border wall on wildlife include increased wildlife mortality, disrupted wildlife migrations, reduced wildlife populations and altered waterflows.
How border walls affect migration patterns?
The model thus highlights four mechanisms through which a border wall expansion can affect migration: (1) a detour effect, where migration flows decrease because migrants either have to surmount the wall or avoid it by using longer or more difficult routes; (2) a diversion effect, where migration flows increase to
How do borders impact the environment?
Today more than 650 miles of border wall stand in California, Arizona, New Mexico, and Texas. Walls tear through wildlife refuges and wilderness areas, national monuments and national forests, damaging endangered species' habitat and damming natural watercourses.
