Abstract:

Northern bog lemmings (Synaptomys borealis) were discovered in 1992–1993 in single patches within the Cody Creek and South Fork Hawkins Creek drainages. During the 1994 field season the authors surveyed these two drainages to determine the number, size, and location of other suitable habitat patches. No suitable patches larger than about 50 m2 were located. The total number of known bog lemming sites in Montana is 18, the greatest number of sites in any of the lower 48 states. Known sites in Montana range in size from 1 to approximately 340 acres. The best habitat predictor for potential northern bog lemming sites in Montana is the presence of large, thick moss—particularly sphagnum—mats.
