SKAMANIA COUNTY, Washington — Sawmills have been closing across the Pacific Northwest over the past 30 years. There is just one left in Skamania County, down from six during its logging heyday. Limited log supply from the region’s national forests has cut off their raw material, while cheap lumber from Canada has taken market share for their finished product. Owners of the remaining mills have high hopes that President Trump will deliver relief by increasing logging in national forests and raising trade protections against Canadian exports. Although the latter can be achieved with a stroke of the president’s pen, meaningfully boosting the federal timber harvest could take years and be impeded by litigation and red tape. …US sawyers have argued successfully in trade cases that their Canadian competitors are supplied with subsidized government logs, and that they offer two-by-fours over the border for less than they sell them at home.
