Small-diameter Hardwood Markets, Revisited
The Forest Service’s Northern Research Station continues to lead efforts to find new markets and processing efficiencies to add value to low-value hardwoods. Over many years, many sawmill studies have been conducted to shed light on sustainable utilization of the full diversity of timber resources across our landscape. At the request of the primary processing industry and landowners, the most recent effort focused on value-added utilization of logs with small-end diameters less than 10 inches. Forest Service scientists found these logs can produce lumber volume recoveries that are comparable to or greater than those of somewhat larger logs (10-13 inch diameter), logs that are established as profitable sawmill inputs. Lumber grade yields are highly variable among small-diameter logs so procurement specifications and drying systems need to be adapted to guarantee sawing smaller logs will yield profits.
