Quantifying carbon stocks in Pinus pinea stands: simple allometric models using easily measurable tree variables

Allometric models establish relationships between tree morphological parameters and the respective biomass in its various components, allowing to make forest carbon estimates. In this sense, this study aims to develop models for the stone pine (Pinus pinea) gathering biomass information from sampled trees in Portugal, Spain, and Italy. These models use simple-to-measure tree variables (diameter at breast height – d, and total height – h) and are suitable for obtaining carbon estimates of aboveground biomass and roots in stone pines across the Mediterranean region.
