Pre-commercial and Commercial thinning in the Northeast USA | FGrOW Webinar Series #13

Presented by Anil Kizha and Libin Louis Abstract Developing and implementing thinning prescriptions are considerably more challenging than clearcut harvesting. Factors influencing the effectiveness and efficiency of thinning operations/outcomes include the: silviculture prescription, species harvested, stand composition, market factors, desired residual stand conditions, and the selection and combination of harvest equipment. This presentation summarizes seven years of applied research in thinning, conducted across ten timber harvesting operations in the Northeast United States. The types of thinning operations that were studied include: pre-commercial thinning (PCT), early commercial thinning (ECT) and commercial thinning (CT). Residual stand condition and damage was quantified in relation to the various harvesting methods and the cost and effectiveness of Best Management Practices (BMPs) designed to reduce the impact of harvest equipment on forest soils will also be discussed. Harvest productivity and costs will be compared by harvesting method across contrasting silvicultural prescriptions. Finally, a global meta-analysis of the factors affecting harvest productivity and costs for ground-based equipment will be presented. The majority of these studies were conducted on long-term research plots, which provides the additional opportunity to track impacts over the full rotation.
