Over 45,000 acres of waterfowl production areas (WPAs) are open to public hunting, including the high number of wetlands on these properties. In many parts of the District, the abundance of wetlands attracts waterfowl breeding pair densities in the spring of over 100 pairs per square mile. In the fall, many birds remain and other migrants use the area on their journey south. This pattern creates excellent waterfowl hunting opportunities for Canada geese and a variety of dabbling and diving duck species. The grasslands harbor good numbers of pheasant, gray partridge and sharp-tailed grouse. Many WPAs have excellent white-tailed deer habitat, and hunters experience high success rates. There are many opportunities to pursue furbearers on these public lands. Hunting is allowed in accordance with North Dakota State Game and Fish Department and refuge regulations.
