President Trump is promising to unleash the US timber industry by allowing companies to raze swaths of federally protected national forests. …His order — which calls for the ramping up of the domestic timber production to avoid reliance on “foreign producers” — was followed by sweeping 25% tariffs on Canadian products, including lumber. …However, it’s more complex than simply swapping out Canadian imports for homegrown timber, said industry experts. …Meanwhile, environmental groups say clearcutting national forests will pollute the air and water and exacerbate climate change. Anna Kelly, White House deputy press secretary, referred to multiple organizations that have released statements of support about opening up federal land for logging, including the American Loggers Council, the American Forest Resource Council and the Forest Landowners Association. Increasing logging on federal lands would increase the supply of logs for US industry, said FEA’s Rocky Goodnow… but it won’t replace Canadian imports in the near term.
