H.R. 8438, the Wildlife Corridors and Habitat Connectivity Conservation Act of 2026, establishes a federal program to protect and restore pathways that allow wildlife to move safely across landscapes for migration, dispersal, and adaptation to climate change. The bill designates National Wildlife Corridors and requires federal agencies to manage these areas by maintaining habitat connectivity, preventing development that blocks wildlife movement, installing wildlife crossings on roads, and removing mining restrictions in corridor lands. Federal agencies must update their regulations and policies within two years to align with corridor protection goals and work with state and local transportation departments to address road barriers. The bill authorizes $140 million annually in federal funding, including $5 million for scientific research and mapping, $60 million for federal land conservation efforts, and $75 million for grants to support habitat projects on private lands, with at least 10 percent of the grant funding specifically dedicated to protecting big game migration routes. This legislation affects federal land managers, state and local governments, private landowners, and transportation departments across the country.
