“…Furthermore, the results of the Kolmogorov-Smirnoff test proved the normality of the distribution of the residuals, and the analysis of the scatterplots did not show patterns of increasing error variance when increasing the independent values. TheS (%) of the selected equations, ranging between 21.3% and 26.6%, was within the range reported by Pastor et al (1984) and Zianis and Mencuccini (2003) for regressions (for mature trees) developed from field data.…”

Abstract• In the present study, allometric biomass equations were developed for Nothofagus pumilio natural regeneration relating foliage, stem and branches (aboveground), roots (belowground), and total biomass to basal diameter and total height, based on destructive measurements of 390 naturally regenerated seedlings and saplings.• Basal diameter was the most important independent variable in all equations and accounted for more than 88% of the variability of the different biomass components. The addition of height as a second independent variable slightly improved the predictions.• The best-fit biomass components equations that were based on combinations of basal diameter and height as independent variables had adjusted R 2 values between 0.80 and 0.95 and a mean percent standard error between 21.3% and 26.6%.• Based on the best-fit biomass equations and the natural regeneration development in a 14-years chronosequence in forests managed under shelterwood cuts, the total biomass varied from 0.9 Mg ha −1 (0.5 Mg ha −1 above and 0.4 Mg ha −1 belowground) for the primary forest, before the shelterwood cuts, to 19.5 Mg ha −1 (13.6 Mg ha −1 above and 5.9 Mg ha −1 belowground) 14 years after the seed cut. In the same period, carbon storage varied, from 0.5 Mg ha −1 to 9.8 Mg ha −1 .

Des mesures destructives ont été réalisées sur 390 plants régénérés naturellement et de jeunes arbres.• Le diamètre à la base était la plus importante variable indépendante dans toutes les équations et représentait plus de 88 % de la variabilité des différentes composantes de la biomasse. L'ajout de la hauteur en tant que deuxième variable indépendante, a légèrement amélioré les prédictions.• Le meilleur ajustement des équations des composantes de la biomasse, fondées sur des combinaisons du diamètre à la base et de la hauteur comme variables indépendantes, a produit des valeurs de

“…Biomass equations for individual trees have been produced in studies of forest production and its correlation with stand density (Baskerville, 19651, in studies comparing biomass and production for individual tree species (Pastor and Bockheim, 1981), and in studies on forest fuel estimation (Agee, 19831, etc. As a result, several different biomass estimation equations are reported in the literature for the same species.…”

The paper presents a comprehensive review of the biomass equations for 65 North American tree species. All equations are of the form M = a@, where M is the oven-dry weight of the biomass component of a tree (kg), D is diameter at breast height (DBH) (cm), and a and b are parameters. Equations for the following tree components were included in the review: total aboveground biomass, stem wood, stem bark, total stem (wood and bark), foliage, and branches (wood and bark). A total of 803 equations are presented with the range of DBH values of the sample, sample size, coefficient of determination R2, standard error of the estimate, fitting method used to estimate the parameters a and b, correction factor for a bias introduced by logarithmic transformation of the data, site index and geographic location of the sampled stand(s), and a reference to the paper in which the equation (or the data) was published. The review is a unique source of equations that can be used to estimate tree biomass and/or to study the variation of biomass components for a tree species. 0 1997 Elsevier Science B.V.
