Species-specific and generalized biomass models for estimating carbon stocks of young reforestations

Biomass models are key to the correct quantification of aboveground biomass and carbon stocks. Most current available sets were developed for adult trees although very few have been employed accurately estimate during first years reforestations, despite increasing number reforestations over recent years. In this study, species-specific generalized single main 14 species used in Spain. A comparison with existing at individual tree level larger these was also conducted confirm hypothesis that specific required reforestation. new set fitted simultaneously per species, based on three different independent variables – root-collar-diameter, total height crown projection area- their combinations. The provide more accurate unbiased predictions after reforestation when compared previously trees. can be applied is unknown or mixed plantations where not individualized. provided a wide variety surveys monitoring conditions depending data, from classical field inventories novel approaches such as airborne LiDAR data aerial photographs. • Species-specific those most Generalized presented identity unknown.
