The complete county distribution, spread across 79 Ohio counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Northern short-tailed shrew reports follow an unusual Ohio calendar. Monthly totals climb steadily from winter through spring, rise further in June and July, and reach their clear high point in September. That late-summer and early-fall concentration sets this record pattern apart from the spring peaks of many larger Ohio mammals. It may also reflect seasonal fieldwork and detection effort.

Cuyahoga Valley National Park and Wayne National Forest place the suggested settings in northeastern and southeastern woodlands. Erie and Ottawa counties, along with the Old Woman Creek preserve, add a wetter Lake Erie landscape. Together, they point to records across very different parts of Ohio. NatureServe ranks the shrew S5, or secure statewide, though that status doesn’t measure local numbers.
