The complete county distribution, spread across 14 North Dakota counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

North Dakota holds one of the stronger prairie shrew records in the upper Midwest. There are 133 reports, led by Grand Forks County with 36, Bottineau with 30, and Stutsman with 29. That spread runs from the Red River Valley up into the drift prairie and across the pothole country. It fits a grassland shrew at home wherever meadow cover holds moisture. By raw record count it sits in the upper tier of the state’s documented mammals. That standing reflects survey effort as much as abundance.

The calendar has a quirk. October, not midsummer, produced the most dated records, with June through August also strong. Shrews get easier to trap as vegetation dies back in fall. The pattern suggests autumn survey work has carried much of the documentation. NatureServe hasn’t assigned the species a state rank. North Dakota’s shrew story is written mostly by these scattered specimens, solid in the east and north, thin west of the Missouri.
