Federal bill would map and protect wildlife travel corridors nationwide

What does this do?

HR 8438 establishes a national system to designate, map, and manage wildlife corridors — stretches of land or water animals use to move between habitats. The U.S. Geological Survey would map existing and needed corridors, while the U.S. Fish and Wildlife Service would officially designate federal lands and waters as National Wildlife Corridors. On designated federal lands, new development, mining, and resource extraction would be restricted.

Who does it affect?

The bill affects federal land managers, state wildlife agencies, tribal governments, transportation departments, and private landowners who choose to participate voluntarily. A coordinating committee of federal agencies, tribal organizations, and conservation experts would oversee implementation and report to Congress.

Why does it matter?

Restricting development on federal corridor lands and requiring highway modifications such as underpasses and fencing would alter how agencies and road builders operate in those areas. Private landowners and states retain existing rights, and the military may opt out of corridor rules when national security requires it.

What does it cost, and who pays?

• Up to $75M per year in grants
• Min. 10% for big game migration routes
• Private and non-federal land eligible
