Indiana has just 2 prairie vole records from 2000 on, both from the Indianapolis area in Marion and Hamilton counties, and they haven’t been refreshed lately: the newest verified report dates to September 2018. Older specimen records, outside that window, hug the state’s western and southern counties, from Posey at the Wabash’s mouth around to Jefferson on the Ohio River, which fits a vole that came in with the tallgrass and never took to the eastern woods.
Runway country
You rarely see a prairie vole so much as its handiwork: narrow, clipped runways threaded through dense grass, with little piles of cut stems alongside. Any old field or ungrazed meadow with a thick thatch can hold a colony, even at the eastern edge of the range.
Too few recent records for a calendar
The two recent records fall in May and September, too few to show a season. Colonies breed from spring into fall, so their numbers build all season and reach their highest point just as the first frosts hit, when fresh runways are also easiest to spot in browning grass. Voles don’t hibernate, so any winter lull in reports says more about observers than animals.
Status in Indiana
NatureServe ranks the prairie vole S5, secure, in Indiana, and it’s a native resident, not a newcomer. Even so, a species last verified in the state in 2018 could use fresh eyes: a documented sighting from anywhere in the state would confirm this pair-bonding little grassland rodent is still going about its business at the edge of its range.
