The complete county distribution, spread across 11 Idaho counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Fourteen records scattered across eleven counties: that’s Idaho’s file on the western spotted skunk, and the scatter is the story. No county holds more than two reports. They reach from Latah and Lewis in the north to Cassia and Power along the Utah line, with a pair in Canyon and Washington counties out west. This is a nocturnal, retiring animal that most people never see, so the record reads as a drift of chance encounters, roadkills, and camera-trap surprises rather than any real map of where it lives.

December produces the most reports, an odd peak for a mammal. Cool-season records for spotted skunks often come from den sites and winter road mortality rather than active animals, and with a sample this small, a few chance finds can tilt any month.

NatureServe still ranks the species S4, apparently secure, in Idaho. Rocky outcrops, rimrock, and brushy canyon country along the Snake River corridor give it plenty of ground, and the state’s wide scatter of records, thin as it is, at least says the skunk turns up everywhere.
