Wisconsin Northern Flying Squirrel records are strongest in Chequamegon-Nicolet and other northern mixed forests, where mature trees, cavities, and moist forest structure support nocturnal movement. Reports from the Necedah region mark a more central setting worth noting; the June–September peak coincides with nest-box checks, field surveys, and the season when observers spend more nights outdoors.
Only 24 of 107 records are from iNaturalist, so institutional and targeted survey data strongly shape the picture. Records are detections, not abundance, and the species’ S2 rank makes it especially important not to turn a cluster of nest-box or trapping records into an inference about population density.
