Data collected from recently harvested even-aged New York nonindustrial private forestlands are used to examine some of the challenges and opportunities associated with expanding woody biomass markets in the context of timber management. Assessments of existing harvesting practices on sampled stands indicate that diameter limit and premature cutting are pervasive. Increases in the demand for woody biomass may exacerbate this exploitive harvesting. However, expanding woody bioenergy markets also might help increase the use of silviculture on these forests by providing much needed small-diameter and low-grade markets. Silvicultural simulations indicate that 6.75 oven-dried tons per acre of woody biomass could have been removed, while simultaneously harvesting a sustainable volume of high-quality sawtimber, leaving an appreciable amount of larger and higher-quality stock for future growth, refraining from premature cutting, and regenerating mature forests.
