[Vedettes matières IGN] Végétation et changement climatiqueRésumé : (auteur) There is an increasing demand on the monitoring of the forest resources, on forests statistics, and on projections of future forest resource availability especially in terms of biomass (Leban & Bontemps, 2016). We developed a new method to enrich the forest information produced by the French National French Inventory by the measurement of the wood density. This technological innovation permits the fast and reliable measurement of the wood density on unprepared increments cores collected in the forests by the NFI staff. The cores are passed through a medical Xray scanner. Since 2015, about thirty thousand cores were sampled each year. At the end of this project, in November 2019 we will have a novel data base with wood density measurements on more than one hundred thousand increment cores. We will present several preliminary results that illustrate the different ways to enrich forest information, e.g. (i) the reassessment of the total standing biomass for the main forest species and (ii) the wood density models that can be used for the simulation of the forest biomass changes at the national level for different climatic hypothesis. We will present and discuss the perspective for the analysis and the sharing of this new data base that combines at the national scale level wood density and the usual forest inventory measurements such as DBH, height, age etc. Such data base pave the avenue for a better understanding of the biomass production along different climatic and trophic gradients.
