Virginia’s 20 records sketch two very different Virginias for the southern bog lemming. One set climbs the western mountains: Giles County leads with 5 records, and Bath, Highland, Augusta, and Rockingham counties line the Alleghenies, with Jefferson and George Washington national forests the top named sites. The other set sits near sea level around Chesapeake and Suffolk, on the doorstep of the Great Dismal Swamp. Wet ground links the two; elevation doesn’t seem to matter much to an animal that follows moisture and dense cover.

A sparse, season-spanning record

Only a handful of the records carry firm dates, and they span January, February, July, and September. That’s too few for any seasonal read, but it does match what the species does everywhere: it doesn’t hibernate, and it works its hidden runways in every month, winter snow included.

Secure, but worth a closer look

NatureServe ranks the species S5 in Virginia, secure, the strongest grade on its scale, and it carries no separate state listing. That confidence likely rests on the mountain populations. The coastal plain tells a thinner story: the wet, peaty ground of Great Dismal Swamp National Wildlife Refuge, Back Bay National Wildlife Refuge, and Mason Neck National Wildlife Refuge suits the species well, yet confirmed records from those refuges are scarce. For a rodent this hard to detect without traps, the gap between good habitat and confirmed reports is exactly where future surveys matter.
