BOARDMAN, Ore. — The poplar trees here grow 10 feet a year, transforming an irrigated stretch of desert near the Columbia River into a neatly pruned forest. For now, the trees provide lumber for cabinets and pulp for paper.
But in the years ahead, energy entrepreneurs hope the pulp from poplar can be turned into ethanol, helping resuscitate the Northwest’s floundering biofuels industry.
