Effects of Two Haying Provisions on Duck Nesting in Conservation Reserve Program (CRP) Fields in South Dakota
Duck nesting in Conservation Reserve Program (CRP) fields was evaluated in 1989 and 1990 to determine the post year effects of emergency haying. Due to severe drought some CRP fields were released in 1988 for emergency haying with the provision that 10% be left in idled strips and some fields were …

Optimal participation in the Conservation Reserve Program: Land enrollment decisions in a stochastic, dynamic framework
… lands culminated in the establishment of a Conservation Reserve Program (CRP) through the 1985 Food Security Act. The Act authorizes the Secretary of Agriculture to enter into ten-year contracts with farmers, paying them an annual rental fee for withdrawing highly erodible cropland from …

Effects of Grazing Intensity and Temporal Application of Grazing Treatments on Nongame Birds in North Dakota Mixed-Grass Prairie
… repeated, one in native prairie and the other in Conservation Reserve Program (CRP) grasslands, to determine the temporal effects of grazing systems on nongame bird populations and habitat. In addition, two earlier studies, conducted at CGREC were repeated, one in native prairie and the other in …

Seasonal Use of Conservation Reserve Program Fields By White-Tailed Deer in Eastern South Dakota
Seasonal use of Conservation Reserve Program (CRP) fields by white-tailed deer (Odocoileus virginianus) was investigated in eastern South Dakota by systematically relocating radio-marked deer from 15 September 1989 to 31 December 1990. Seasonal core areas and low use areas were determined from 40 …

Effects of Wind Turbines On Nongame Birds in Conservation Reserve Program Grasslands in Southwestern Minnesota
… on nongame bird composition and density in Conservation Reserve Program (CRP) grasslands was evaluated in summer 1995 along Buffalo Ridge in southwestern Minnesota. Bird density in CRP fields with wind turbines was compared with that found in cropland, pastureland, woodland, and CRP …

Small mammal demographics in North Dakota conservation reserve program plantings
… mammal demographics and population dynamics in Conservation Reserve Program (CRP) plantings in north central North Dakota. Four age classes (1-4 years) of CRP plantings were sampled. Small mammal species diversity was low (H'=0.057-0.374). Eight species of small mammals were captured on CRP …

Wildlife management on Virginia Conservation Reserve Program land: the farmer's view
… questionnaire concerning wildlife management on Conservation Reserve Program (CRP) land was sent to one-half (n = 808) the enrollees in Virginia selected at random. Results from a 76% return indicated that 72% wanted to improve the wildlife habitat on their retired land. These respondents felt …

Influence of the Conservation Reserve Program and Landscape Composition on the Spatial Demographics of Prairie Grouse in Northeastern South Dakota
… prairie grouse in North America. Conversely, the Conservation Reserve Program (CRP) of the Federal Food Security Act of 1985 converted millions of cropland acres back to perennial grassland. These large-scale land use changes have undoubtedly impacted prairie grouse abundance and distribution. I …

Assessing Arbuscular Mycorrhizal Fungal community composition and diversity across a land-use gradient in Eastern Washington prairies
… land-use types: remnant native prairies (n=9), Conservation Reserve Program (CRP) (n=10) lands, conventional-till farmland (n=11), and no-till farmland (n=7). AMF DNA extracted from soil samples, was amplified using the AMF-specific primer pair NS31-AML2 and sequenced on the Illumina MiSeq …

Use of restored grasslands by mammals in a dynamic agroecosystem: insights from camera trapping
… prairie has been lost in Illinois. Restoration programs such as the Conservation Reserve Program (CRP) and State Acres for Wildlife Enhancement (SAFE) were created in part to ameliorate grassland loss. Previous assessments of responses of mammals to grassland restoration efforts have not focused …

Costs of maintaining the conservation reserve program in Illinois in the presence of biofuels
The Conservation Reserve Program (CRP) has played a key role in reducing soil erosion, improving water quality and protecting wildlife habitat. Rising crop prices, partly induced by the expansion of biofuel production, is likely to increase the maintenance cost of the program. This study develops a …

Avian Nesting Densities and Success in Introduced Cool-Season Grass-Legume Plantings Versus Warm-Season Native Grass Planting in South Dakota 2002-2003
… many grassland bird species have declined. The Conservation Reserve Program (CRP) has restored more than 14 million hectares of prairie and idle grassland. Studies indicate that warm-season native grass plantings (WSN) generally provide good winter cover. Recently a trend favoring WSN has …

Impacts of and willingness to pay for conservation and restoration in the U.S.
Ecosystem conservation and restoration in rural and urban areas of the United States not only provide a variety of environmental benefits, but may also generate other unintended impacts on local economies, social structure, and urban well-being. This dissertation focuses on three complementary …

Simulating the Soil Erosion from Land Removed from CRP
<p>A survey of South Dakota Conservation Reserve Program (CRP) contract holders, conducted in 2007, indicated that large areas of land in the CRP could be returned to grain production in the next four years. Conversion of these acres from CRP back to row crop production without regard to …
