Eastern red bats carry a NatureServe S5 secure rank in Arkansas, a healthier state-level read than the species’ G3 global rank, which reflects broader range-wide vulnerability, largely from wind-turbine mortality during migration. Ouachita National Forest’s 2 logged sightings and Buffalo National River’s 1 anchor a record that leans toward GBIF (225 of 249), suggesting acoustic and capture surveys, not casual photographs, document most of what’s known about this solitary, foliage-roosting bat here.

July and August together account for 120 of the 249 records, nearly half the year’s total, tracking peak maternity-colony activity; records nearly vanish in January and November, consistent with the bat migrating south for winter.
