Northern Prairie Wildlife Research Center
Only about 1 percent of North Dakota is forested. Most of this forest occurs along the state/river valleys. Although we have the lowest percentage of forest lands of any state, we still have a tremendous potential for increasing the abundance of our cavity-nesting waterfowl.
By engaging in the projects described in this circular, you can establish cavity-nesters in areas where none have nested before. Once you get birds established, you are well on your way to building local populations that will readily accept and use your safe homemade nest boxes.
Figure 20. The end result of you efforts to build, properly place and maintain your nest boxes is that cavity nesters will use your boxes to lay, incubate and hatch a clutch of eggs. Above, a wood duck hen incubates her eggs in a double compartment wood nest box provided for her along the James River south of Jamestown, N.D.
