USDA is an equal opportunity provider and employer. Finding out what bobwhites want

he U.S. Department of Agricul- ture (USDA) Natural Resources TConservation Service (NRCS) Agricultural Wildlife Conservation Center (AWCC) led the Bobwhite Res- toration Project, a cooperative effort among multiple agencies designed to develop and evaluate the technology needed to establish or manage the habitat needed to restore northern bobwhite populations to 1980 levels. The technology will assist NRCS field staff in future planning by evaluat- ing the effects of NRCS conservation practices on northern bobwhite habi- tat and populations. The new technol- ogy will assist in meeting a goal of the Northern Bobwhite Conservation Initiative (NBCI)­—adding 2,770,922 coveys to current populations. Partners include Mississippi State University (MSU), Forest and Wild- life Research Center, Department of Wildlife and Fisheries (MSU), Quail Unlimited, Inc. (QU), and the South- eastern Association of Fish and Wild- life Agencies (SEAFWA). The Department of Wildlife and Fish- eries at MSU is the umbrella institu- tion that coordinated 11 research proj- ects among 9 universities. States with research projects include , , Illinois, Mississippi, , North Carolina, South Carolina, Ten- nessee, and . This booklet summarizes 13 studies from the project. More detailed infor- mation on the project is available by contacting the AWCC or visiting the USDA NRCS Bobwhite Restoration Project Web site at http://www.cfr. msstate.edu/nbci, Finding out what bobwhites want.

This booklet was developed by Iowa State University Extension Wildlife Programs for the NRCS Agricultural Wildlife Conservation Center as part of a CESU coopera- tive agreement. NRCS photos by Lynn Betts
