The complete county distribution, spread across 1 Kansas counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Kansas has a single little brown bat record from 2000 on, an iNaturalist observation logged in August 2022 in Crawford County, in the state’s southeast corner. One record can’t show where the species roosts or when it’s most active here.

An August date fits a bat foraging over farm ponds and streams in the warm months, but a lone record can’t say whether Kansas matters to it more as hibernation country or as summer range.

The official standing is sobering. NatureServe ranks the species S3, vulnerable, in Kansas, and the IUCN lists it as Endangered globally after white-nose syndrome collapsed populations across the East. A bat that was once ordinary over farm ponds and town lights now earns a conservation rank in nearly every state where it’s tracked, Kansas included.
