A sub-program of the Conservation Reserve Program, CREP is a state-federal multi-year land retirement program developed by states and targeted to specific state and nationally significant water quality, soil erosion, and wildlife habitat problems. CREP uses the state funds to offer higher payments per acre to participants than the CRP. States may enroll up to 100,000 acres through an approved CREP, and at least three states have more than one CREP. USDA has reserved 4 million acres from the authorized 39.2 million acre total to enroll through either this option or the continuous enrollment option. Currently, 26 states have approved CREPs, and through March 2005, more than 645,000 acres had been enrolled under this option. As of June 2005, proposals are pending for 7 additional states.
