The complete county distribution, spread across 29 Utah counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Long-tailed vole records point away from the open water of Great Salt Lake and toward Utah’s cool, grassy mountain ground. Wet meadows and brushy stream edges in the Wasatch and Uinta high country provide a better reading of its habitat than the broad refuge names attached to the records.

The reporting curve is strongly weighted toward July through September. Summer access to high country and seasonal field surveys likely shape that peak, so it shouldn’t be treated as a measure of vole numbers.
