    Description

    Biomass models for most commercially important hardwood species in the northern region of the U.S. are often based on data of very limited spatial extent and range of tree characteristics, suggesting uncertain accuracy when applied at regional scales. Also, the current models can have poor predictive ability for the proportions of biomass found in major tree components considered for utilization, namely the merchantable bole, bole tops, tree branches, and foliage. The Forest Inventory and Analysis Program of the U.S. Forest Service is currently undertaking a project to obtain regionally representative data to develop new volume/biomass models. This paper outlines issues related to challenges in data collection and subsequent modeling of biomass components for hardwood species.
