The complete county distribution, spread across 10 Oregon counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Wild boars aren’t native to Oregon, and NatureServe classifies the species as exotic here rather than assigning a conservation rank. Unlike the well-established feral hog populations that plague parts of the Southeast, Oregon’s showing is thin, just 19 total records, consistent with scattered escapees from game farms rather than a self-sustaining wild population.

Records scatter across January, March, May, June, and December with no dominant month, too few and too uneven to describe a real seasonal pattern. Oregon has actively worked to prevent the kind of established feral swine population seen in other states, and the record here reflects that low, contained presence.
