Based on aerial surveys (2004–2007, adjusted for sightability) and subjective estimates for unsurveyed areas, I developed an estimate of the total number of mountain goats (Oreamnos americanus) in Washington State, USA. Mountain goat populations were estimated for 56 units, 40 areas, and 21 zones, yielding a total 2,815 (2,401–3,184) mountain goats. Of the units/areas/zones identified, about 60% have been monitored with aerial surveys. For the remaining areas, the estimate for Lake Chelan was based on ground counts and the rest subjectively estimated. Additional aerial surveys around Mount Adams, for Mount Rainier National Park, the North Wenatchee Mountains, and the Chiwawa River area would enhance our knowledge of mountain goat populations in Washington.
