Wildlife Corridor and Crossings Policy Options
Overview
Wildlife populations are on the decline in the U.S. Habitat fragmentation could have lasting negative effects on wildlife populations, ecosystem functions, and recreation for millions of Americans. Wildlife is losing the ability to move, migrate, and disperse across landscapes right as climate change is pushing many species to move in new patterns and places. In addition, wildlife-vehicle collisions put people and wildlife at risk of injury and death, while costing billions each year. Wildlife corridors and wildlife crossings are vital and cost-effective ways to maintain resilient ecosystems and to protect public health and safety.
