The complete county distribution, spread across 15 Florida counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Ordway-Swisher Biological Station holds 160 of Florida’s 194 golden mouse records, and the other named sites, among them Blue Spring State Park, Withlacoochee State Forest, and Lake Talquin State Forest, carry a single record each, though the species’ real range reaches well beyond those places. With one research station dominating, the record set traces where observers have gone more than where the mouse itself is limited to.

Florida’s reports climb into a summer plateau, with July narrowly ahead of May as the year’s high point and June next. That timing doesn’t prove when golden mice are most active, since detection depends heavily on trapping effort and observer timing rather than the animal’s own rhythms.
