The complete county distribution, spread across 12 Washington counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Across the Washington overlay, wild boar is represented by 17 records. iNaturalist accounts for 13 records and GBIF for 13; those figures describe reporting systems, not animals on the ground. On the atlas scale, the species occupies position 103 of 126.

Its clearest calendar contrast is December’s 4 records versus June in 0. Suggested locations span Colville National Forest and Turnbull National Wildlife Refuge, but no site-level counts compare them. The evidence measures when and where records entered the dataset, rather than biological abundance.
