Abstract The feasibility of using plantation‐grown biomass to fuel bioenergy plants is in part dependent on the ability predict capacity surrounding forests maintain a sustainable supply. In this study, potential productivity Eucalyptus nitens (Deane and Maiden) Maiden plantations grown for region north‐west Spain was quantified 3‐ PG process‐based model. model calibrated detailed measurements from five permanent sample plots validated data thirty‐five additional plots; both sets represented variability climate soils region. Plot scale analysis showed that able reasonably estimate above‐ground water use when compared with observed data. Using representative loam soil characteristic, spatial then carried out E. across area plantation establishment 2550 km 2 evaluate different management scenarios related rotation length stocking.

Production reduced by low summer rainfall lesser extent high winter temperatures, vapour pressure deficit.
