Plot level biomass by components for small black spruce trees growing on the wetlands of the Boreal and Taiga Plains of Canada

Tree mensuration data and biomass component data, collected from destructive sampling of 679 trees (DOI: 10.5281/zenodo.10632743), were scalled-up to the plot level, resulting in 58 black spruce boreal wetland plots within the Boreal Plains and Taiga Plains of Canada. This dataset contains plot level biomass by components for small black spruce trees growing on the wetlands of the Boreal and Taiga Plains of Canada. This dataset has been used to develop a new set of yield curves (i.e., total volume as a function of total stand age) as well as novel total volume-to-biomass conversion models to predict stem wood, stem bark, branch, and foliage biomass of the small black spruce trees. The novel equations are key to modelling treed peatlands in the Canadian Model for Peatlands (CaMP) and thus contribute to improving accuracy in modelled C stocks and flux estimates for Canada’s treed peatlands.
