South Carolina’s deer mouse record tilts toward the mountains. Oconee, Greenville, and Pickens counties, the state’s Blue Ridge corner, hold 9 of the 22 reports, and the named sites, Sumter National Forest’s mountain districts, the Jocassee Gorges, Caesars Head, are all upstate ground. That’s classic deer mouse country: a largely northern and western species that reaches the Deep South mainly along the Appalachians.
The outlier is Lexington County in the midlands, with 7 reports, the most of any county. Whether that’s a genuine lowland population or a run of misidentified white-footed mice, which look nearly identical and are far more widespread in the state, is the kind of question a thin record can’t settle.
March is the busiest month in a calendar that shows no real pattern. NatureServe ranks the species secure in South Carolina, but its documented footprint remains small and mountain-skewed.
