The Conservation Reserve Enhancement Program (CREP) is a supplementary program of the federal Conservation Reserve Program (CRP), the largest US land retirement program targeted to highly erodible areas. Established in 1996 to better target environmental benefits, CREP is a federal-state partnership administered by the Farm Service Agency (FSA) that pays land owners who choose to participate in the program an annual rental rate for removing environmentally sensitive land from production and introducing conservation practices on the land. CREP addresses high priority conservation issues identified by local, state, or tribal governments or by non-governmental organizations. Participation agreements typically last 10-15 years and often include other federal and state incentives1, 2.
Expected Beneficial Outcomes (Rated)
Increased wildlife habitat
Reduced soil erosion
Other Potential Beneficial Outcomes
Improved soil quality
Improved water quality
Evidence of Effectiveness
There is some evidence that the Conservation Reserve Enhancement Program (CREP) increases wildlife habitat3, 4, 5, 6 and reduces soil erosion2, 7. Studies of the federal Conservation Reserve Program (CRP), which includes CREP, also show improvements to wildlife habitat8 and reductions in soil erosion9. Additional evidence is needed to confirm CREP’s effects.
CREP and CRP both establish perennial ground cover that improves wildlife habitat and water quality4. Program benefits can vary widely, and are often dependent on landowner cooperation and the conservation practices used; practices vary by ecosystem and wildlife species2. Prioritizing highly erodible, sensitive land parcels within the CREP approved area during the CREP enrollment period, instead of approving applications on a first-come-first-served basis, can reduce program costs and maximize reductions in soil erosion2.
In a 2010 report to Congress, the Farm Service Agency (FSA) estimates that CRP, including CREP, reduced erosion by more than 454 million tons per year, restored 2 million acres of wetlands and 2.5 million acres of buffers, established 3.2 million acres of wildlife habitat, planted 2.7 million acres of trees, and reduced the application of nitrogen (by 681,000 tons) and phosphorus (by 104,000 tons)10.
Impact on Disparities
There are several success stories among state CREP agreements, in particular, CREP agreements have significantly helped improve New York City’s watershed and drinking water, improve the health of the Chesapeake Bay, and mitigate flooding in Washington State1.
