The northern myotis’s most recent confirmed Tennessee record dates to December 2014, more than a decade old on an otherwise open occurrence database. That gap says less about a shy bat and more about a disease that reshaped the eastern bat world in the years since.
Caves in winter, cluttered forest in summer
Great Smoky Mountains National Park, Fall Creek Falls State Park on the Cumberland Plateau, and the hardwood forest around Land Between the Lakes together span the two habitats this bat needs each year: cool limestone caves and mines for hibernation, and dense, cluttered forest canopy for summer hunting. Unlike open-air bats that chase insects in the open sky, the northern myotis gleans prey directly off leaves and bark within the forest itself, a hunting style that keeps it close to trees rather than out over fields or water.
A record frozen by white-nose syndrome
Records here run through 2014 and stop, right as white-nose syndrome was tearing through cave-hibernating bats across the eastern United States. A species already reduced by that disease elsewhere in its range is exactly the kind of animal whose Tennessee paper trail would go quiet without actually disappearing from the landscape; the absence of newer records may reflect a genuine, disease-driven decline rather than simply fewer people looking.
Status in Tennessee
NatureServe ranks the northern myotis S1, critically imperiled, in Tennessee, far below its global Near Threatened status, a gap that fits a species hit hardest in its eastern cave-wintering range. It’s native to the state, where any recovery depends on protecting the same caves and forest roost trees this bat has always needed.
