This bill amends the Federal Land Policy and Management Act of 1976 to improve the management of grazing permits and leases, particularly during emergencies. It establishes a process for federal agencies to make vacant grazing allotments temporarily available to existing permit or lease holders whose current allotments become unusable due to extreme natural events or disasters , such as drought, wildfire, or infestation. The Secretaries of Agriculture and the Interior are authorized to implement this provision, considering ecological conditions and prior agreements when establishing temporary terms. This temporary access is designed to provide flexibility for ranchers without altering their original permit terms, their preference to return to their primary allotment, or future animal unit months. The bill also requires the Secretaries to coordinate across agency jurisdictions and establish guidelines within one year to ensure efficient and expeditious implementation of these provisions.
