Partners
Protection runs on partnerships.
REPI and RARI require non-federal partners — land trusts, states, tribes, and willing sellers — to cost-share the easements and acquisitions that keep these corridors open. Lewis & Clark Corridors connects the federal frameworks, the trail authority, and the conservation organizations that make protection happen.

Bring a corridor forward
Land trusts, states, tribes, and willing sellers — we need you.
REPI/RARI projects are cost-shared and built around willing sellers. If you hold or steward land in one of these twelve corridors, or can bring the non-federal match, you're the partner that turns documentation into protection. Reach out.
