In the mid-twentieth century, Anoka County's Carlos Avery Game Farm helped to build populations of dwindling game bird species, such as the bob white quail, chukar partridge, and ring-necked pheasant. A National Register-listed historic district since 1991, it is now part of the nearly 25,000-acre Carlos Avery Wildlife Management Area (WMA) and has become a reserve for deer, waterfowl, and other woodland animals and birds.
