North American deermouse records point toward Reelfoot Lake State Park and the Hatchie and Tennessee national wildlife refuges. Their wetland names tell only part of the story: wooded margins, brush, fields, and dry shelter around those lowland complexes provide the ground cover small mice use. Nearly all Tennessee records come through GBIF rather than casual iNaturalist reports.
Reports climb from April through June and show a second peak in October. January and December are much quieter. That uneven calendar likely carries the imprint of focused trapping and museum surveys, so it describes collection effort and recorded timing rather than mouse abundance.
