From: Carbon fraction of Pinus radiata biomass components within New Zealand
Carbon fraction of stem bark as a function of stand age in New Zealand radiata pine biomass studies. Three sites were sampled at multiple ages: Woodhill (triangles), Kinleith (dots) and Tarawera (crosses). The remaining eight sites were sampled only at one age (circles). The line shows the fitted exponential function: CFstembark = 0.551 × (1 − 0.291 × exp(− 0.280 × Age))
