This bill amends federal land management law to allow ranchers with grazing permits to temporarily use vacant grazing allotments on public lands when their regular grazing areas become unusable due to natural disasters, extreme weather, wildfires, drought, or disease. The Secretaries of Agriculture and Interior can authorize this temporary grazing if they determine the vacant allotment is suitable for use, and they must establish guidelines within one year to manage the process efficiently. The temporary use does not affect ranchers' original permits, their preference to return to their original allotments once restored, or their future grazing authorization amounts. The bill requires federal agencies to coordinate across jurisdictions to make vacant allotments available and to periodically evaluate land health conditions to ensure this emergency relief program operates effectively.
