Western meadow voles carry no NatureServe state rank in South Dakota, SNR unranked, and all 13 of the state’s records come from iNaturalist with no GBIF specimen data, meaning casual sightings, not trapping surveys, document what’s known here despite this being a genuinely difficult species to spot given its small size and dense grass-cover habits.

Records scatter thin across seven months with a September peak (3 sightings), too sparse a pattern to draw a confident seasonal trend from beyond confirming the vole turns up occasionally at sites like Badlands National Park.
