Description (from the abstract):
A study of representative terrestrial vertebrates in the portion of the Missouri Slope south and west of the Missouri River, and McLean County, in North Dakota was undertaken in the summers of 1976 and 1977. Data were tabulated relative to species occurrence and abundance by major habitat type and geographic area. Data were collected from population sampling, existing literature, and unpublished reports and interviews.

All mammals observed on quarter-section quadrats used for bird surveys were recorded. Small mammals were sampled by saturation trapping on 2-hectare subunits of the quadrats. Data on big game and furbearers were obtained from state and federal agencies. Data on endangered and special-interest species were obtained from cooperating agencies and supplemented by field observations and interview.
