Previously published every biennium (two years), the Survey reports key statistics about Washington's wood products processing industry, including: where logs used in sawmills come from by region and land ownership; what mills make from harvested logs, such as veneer, plywood, pulp, boards, shakes and shingles, or posts, poles, and pilings; and how logs are exported. 
 
The Mill Survey was put on indefinite hold at the beginning of the COVID-19 pandemic due to funding constraints. Considerations are underway whether to reinstate it.
