GCubeR (version 0.1.3)

Estimation of Forest Volume, Biomass, and Carbon

Description

Provides tools for estimating forest metrics such as stem volume, biomass, and carbon using regional allometric equations. The package implements widely used models including Dagnelie P., Rondeux J. & Palm R. (2013, ISBN:9782870161258) "Cubage des arbres et des peuplements forestiers - Tables et equations" , Vallet P., Dhote J.-F., Le Moguedec G., Ravart M. & Pignard G. (2006) "Development of total aboveground volume equations for seven important forest tree species in France" , Pauwels D. & Rondeux J. (1999, ISSN:07779992) "Tarifs de cubage pour les petits bois de meleze (Larix sp.) en Ardenne" , Massenet J.-Y. (2006) "Chapitre IV: Estimation du volume" , France Valley (2025) "Bilan Carbone Forestier - Methodologie" . Its modular structure allows transparent integration of bibliographic or user-defined allometric relationships.
