Using existing data sets from three different European countries, a set of robust allometric biomass equations for various tree compartments of European beech was developed based on the relationship between compartment biomass and a surrogate of tree volume. The introduction of stand age as an additional explanatory variable explained most of the variability and accounted for key physiological phenomenon as regard to tree development. Low residual variations were due to management options and stand fertility. At a larger scale and based on our own experimental measurements, the impact of varying soil properties on biomass partitioning pattern and nutrient immobilisations in tree was assessed. This highlighted the importance of considering soil fertility when intensifying harvesting practices in the case of fuelwood-oriented scenarios. Finally, in order to connect the sustainable level of fuelwood exploitation and the actual local needs, the premises of an econometric demand function for fuelwood were established.
