The Conservation Reserve Enhancement Program (CREP) is a supplementary program of the federal Conservation Reserve Program (CRP), the largest voluntary U.S. 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 federal, state, and other incentives (USDA-FSA fact sheet 2019, USDA-FSA CREP, Khanna 2009).

What could this strategy improve?

Expected Benefits

Our evidence rating is based on the likelihood of achieving these outcomes:

  • Increased wildlife habitat
  • Reduced soil erosion

Potential Benefits

Our evidence rating is not based on these outcomes, but these benefits may also be possible:

  • Improved soil quality
  • Reduced run-off
  • Improved water quality

What does the research say about effectiveness? -+

There is some evidence that the Conservation Reserve Enhancement Program (CREP) increases wildlife habitat (Reiley 2020, Yeiser 2018, O'Neal 2008, Sharpley 2009) and reduces soil erosion (Khanna 2003, Khanna 2009). Available evidence associates CREP with increases in wildlife populations; although more land covered by CREP agreements may be needed to reach sustainable levels for wildlife populations (Pabian 2015). Studies of the federal Conservation Reserve Program (CRP), which includes CREP, also show improvements to wildlife habitat (Gleason 2011) and reductions in soil erosion (Smith 2011). Additional evidence is needed to confirm CREP’s effects.

CREP and CRP both establish perennial ground cover that improves wildlife habitat and water quality (Reeves 2016, Sharpley 2009) and reduces run-off (Wiseman 2014). Program benefits can vary widely and are often dependent on landowner cooperation and the conservation practices used; practices differ by ecosystem and wildlife species (Khanna 2009). 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 erosion (Khanna 2009). A Minnesota-based study suggests that long-term contracts are essential to maintain CREP and CRP conversions of cropland to grassland or forest cover and to provide consistent income to farmers (Yuan 2015).

In Washington state, interviews suggest programs identify and base conservation efforts on locally salient values in order to successfully increase CREP enrollments (Chapman 2018). Identifying and understanding motivations for enrolling in a conservation program can also boost enrollment numbers (Pfrimmer 2017). CREP incentives differ depending on many factors; careful and purposeful dissemination of program incentive offers may increase enrollment and diversify the pool of applicants (Manley 2017). 

A Pennsylvania-based study suggests CREP positively influences wildlife populations, in this case, however, the amount of land enrolled in CREP was insufficient to reverse wildlife population declines. A combination of more land enrolled in CREP and additional conservation strategies may be needed to fully restore declining wildlife populations (Reiley 2020, Pabian 2015).

In a 2020 report, the Farm Service Agency (FSA) estimates that since it began CRP, including CREP, it has prevented the erosion of more than 11 billion tons of soil, restored over 3 million acres of wetlands and more than 2 million acres of buffers, significantly reduced nitrogen and phosphorus run-off, and has, on average, helped sequester 48 million tons of greenhouse gases annually (USDA-CRP 2020).

Implementation Examples -+

The U.S. Department of Agriculture (USDA) reports 47 CREP projects across the country, covering 1.1 million acres in 33 states (USDA-FSA CREP). As of March 2020, the Farm Services Agency (FSA) estimates that 21.9 million acres were enrolled in CRP, including about 927,000 acres of CREP enrollment (USDA-CRP 2020, USDA-FSA Statistics).

There are several success stories among state CREP agreements. For example, New York City’s CREP enrolled more than 130 farmers and established over 150 miles of streamside buffers that significantly reduced run-off in the watersheds that provide roughly 90% of the drinking water for New York City residents (CCA-NYC CREP). In Illinois, the CREP program has restored nearly 111,000 acres of bottom lands, reducing soil erosion by 2.5 million tons annually and supporting waterfowl populations and habitat (CCA-Illinois CREP). In Missouri, the CREP program has restored 50,000 acres of riparian buffers to improve water quality and enhance wildlife habitat and has created buffers on nearly 14,000 acres of Missouri farmlands (CCA-Missouri CREP).
