The animals were killed 46-561 km (X = 297) from the nearest known breeding range. Seven wolves were believed to have come from Minnesota and one from Canada, based on skull morphometrics. The probable region of origin of two wolves (wolves 3 and 10; Table 1) was not determined. However, wolf 10 was large (46.4 kg) and of a black color phase, characteristics common of wolves in Manitoba and Montana. These two wolves were killed 561 km and 343 km from the Manitoba wolf distribution, 644 km and 474 km from the Minnesota distribution, and, 756 km and 740 km from the Montana distribution, respectively.
The 10 mortalities occurred in nine different counties. Four of the mortalities were concentrated in a relatively small area in southeastern North Dakota/northeastern South Dakota (1174 km2; Figure 1). Counties where wolves were killed averaged 57% cropland, 36% pastureland, and 1% woodland (Table 1) and had road densities averaging 0.71 km/km2 and human densities averaging 3.5/km2.
