Tennessee’s masked shrew reports cluster in the high, moist forest of the far east, around Great Smoky Mountains National Park, Cherokee National Forest, and Roan Mountain State Park. That’s no accident. This shrew needs damp soil, thick leaf litter, and cool ground, and the state’s southern Appalachian highlands are about as close as Tennessee gets to the cold, wet conditions it favors farther north in its range.
A masked shrew’s metabolism runs so fast that it has to hunt almost nonstop, day and night, just to avoid starving. It threads through moss, rotting logs, and loose soil hunting beetles, worms, spiders, and insect larvae, and it will scavenge carrion or even tackle a small snake when live prey runs short. Its size, barely bigger than a thumb, lets it use tunnels other animals leave behind.
Records here are thin. Only 471 Tennessee occurrences exist, and just 8 come from iNaturalist sightings; the rest are GBIF records from small-mammal trapping surveys, not casual encounters. Reports peak in June, July, and September, which lines up with when those surveys typically run rather than any real shift in the shrew’s own activity. NatureServe ranks it S4, apparently secure, in Tennessee.
