AB Accurate quantification of branch volume in trees is important for sustainable forestmanagement, especially as these fractions are increasingly used for bioenergy, and for preciseforest CO2 quantification. Whereas a large focus has been placed on the compatible estimationof tree taper and bole volume with and without bark, little effort has been made to develop modelsthat allow a simultaneous prediction of these variables together with tree branch volume. In thisstudy, 595 Pinus cooperi trees and 700 Pinus durangensis trees were sampled in pine-oak forests inthe Sierra Madre Occidental, Mexico. A compatible system for predicting two segmented taperfunctions, over and under bark; the corresponding merchantable volumes; coarse branch volumeand whole-tree volume was fitted using a modified continuous autoregressive structure to accountfor autocorrelation. The proposed compatible equations explained more than 97% of the observedvariability in diameter over and under bark, volume over and under bark, and total tree volume andmore than 64% of the observed variability in branch volume in both species. The method describedcan theoretically be replicated for any tree species, thus providing a better understanding of thepatterns of volume distribution by components, potentially improving carbon accounting system andforest bioenergy planning.
