Federal agencies have been given six months to outline how they can develop or restore and protect ecological corridors, including those relied upon by wildlife during their migrations.
Under a memorandum from the chair of the White House Council on Environmental Quality, the agencies have been tasked with maintaining such corridors by "developing policies, through regulations, guidance, or other means, to consider how to conserve, enhance, protect, and restore corridors and connectivity during planning and decision-making, and to encourage collaborative processes across management and ownership boundaries."
