Indiana bats carry NatureServe’s S1 critically imperiled rank in West Virginia alongside a G2 global rank, one of the most severe conservation statuses in this dataset, for a federally endangered species whose entire winter population concentrates in a handful of karst hibernacula. Nearly all of the state’s 89 records, 89 of them, come from GBIF, meaning what’s documented here is almost entirely cave-survey data rather than casual sightings; only 4 records overlap with iNaturalist.
December alone accounts for 58 of the 89 records, nearly two-thirds of the entire year’s total, an unmistakable signature of hibernaculum population counts conducted as bats settle into winter roosts, a single concentrated survey window that dwarfs everything else in the record.
