The Grasslands Reserve Program (GRP) assists landowners and operators in protecting grazing uses and other related conservation values by restoring and conserving eligible grassland and certain other lands through rental contracts and easements. This interim final rule sets forth how USDA, using the funds, facilities, and authorities of the Commodity Credit Corporation (CCC), will implement GRP in response to the changes made to the program by section 2403 of the Food, Conservation, and Energy Act of 2008. In addition, this interim final rule incorporates other changes to the regulation for clarification or program administrative improvement.
