Estimer le volume total d'un arbre, quelles que soient l'essence, la taille, la sylviculture, la station

Pourquoi aborder les volumes en commençant par le volume total de l'arbre, peu familier et difficile à appréhender ? Parce qu'il est total, justement : indispensable pour assurer la cohérence des estimations par compartiment (tige, branches, à telle ou telle découpe).Et parce qu'on en a besoin pour les nouveaux enjeux, ceux du carbone par exemple. La méthode est complexe mais le résultat est là : un modèle général, paramétré pour 28 essences avec aussi une formule simplifiée pour des estimations approchées rapides

GlobAllomeTree: international platform for tree allometric equations to support volume, biomass and carbon assessment

GlobAllomeTree is an international platform for tree allometric equations. It is the first worldwide web platform designed to facilitate the access of the tree allometric equation and to facilitate the assessment of the tree biometric characteristics for commercial volume, bio-energy or carbon cycling. The webplatform presents a database containing tree allometric equations, a software called Fantallomatrik, to facilitate the comparison and selection of the equations, and documentation to facilitate the development of new tree allometric models, improve the evaluation of tree and forest resources and improve knowledge on tree allometric equations. In the Fantallometrik software, equations can be selected by country, ecological zones, input parameters, tree species, statistic parameters and outputs. The continuously updated database currently contains over 5000 tree allometric equations classified according to 73 fields. The software Fantallometrik can be also used to compare equations, insert new data and estimate the selected output variables using field inventory. The GlobAllomeTree products are freely available at the URL: http://globallometree.org for a range of users including foresters, project developers, scientist, student and government staff
