^aHabitat determinizations were by the U.S. Fish and Wildlife Serice National Wetland Inventory from interpretations of aerial photographs of May and July 1982 (all study areas in Canada, Montana, South Dakota, and the Plaza, Sharon, and Streeter study areas in North Dakota) and from outdated photography that was ground-truth corrected in 1987 (all areas in Minnesota and in the Courtenay, Eldridge, Fredonia, Jud, Kulm, and Litchville study areas in North Dakota). See Cowardin et al. (1985) and Greenwood et al. (1987) for details of habitat classification.
^bStudy areas denoted with an asterisk (*) are in the aspen parkland, all others are in the prairie.
^cIncludes hayland.
^dIncludes many different small features such as farmsteads and gravel pits (Cowardin et al. 1985).
^eBarren habitats are roads and similar non-farmed areas.
^ftr = <0.50%.
