Ability to measure wood density is fundamental to forest assessments, genetic improvement programs, and to understand all uses of wood, including carbon capture. The most relevant factors at the tree level are related to growth: thickening of the stem, height growth and structural development of the canopy over seasons. Yet, there is no method that could be used to quantitatively measure tree growth allocation and the only way to measure wood density is via destructive means. Base of this research project will be a detailed laser scanning time series collected from 37 sample plots. Changes in the stem form, height growth and canopy development over seasons can be characterised from the 8-years long laser scanning time series (2014-2022). In this research project, understanding on tree growth allocation will be increased and in order to capture the variability in wood density without destructive means, we will link development of external tree architecture to wood density.
