Southern bog lemming records in Michigan run almost entirely through GBIF, 22 entries against just 3 from iNaturalist, reflecting a fossorial rodent that lives in grass-roofed surface runways and is documented mostly through trapping surveys, not photographs. Ottawa National Forest anchors the record with 9, and Gogebic County, at the western tip of the Upper Peninsula, holds half of all 22.
Most of the 22 reports fall from May through July, the growing season when meadow and sedge cover is thickest and trapping effort typically runs. NatureServe still ranks the species S5, Secure, in Michigan despite the thin photographic record, a case where the record count measures how rarely this lemming surfaces, not how common it actually is underground.
