The bill aims to conserve wildlife corridors and habitat connectivity to combat species decline from habitat loss and climate change. It establishes a National Wildlife Corridor System on federal land, supporting species migration, habitat connectivity, mapping efforts, and research. The system will prioritize habitat conservation and restrict human activities within corridors. It also addresses road mitigation, establishes a Coordinating Committee, and allows for a grant program encouraging wildlife movement and habitat connectivity. The bill emphasizes collaborative efforts, scientific mapping, and funding for conservation and sustainable habitat connectivity on federal and non-federal land.
