[Vedettes matières IGN] Inventaire forestierRésumé : (auteur) Decided in 1958 and actually launched in 1960, the French National Forest Inventory (NFI) now has nearly sixty years of experienceand steady progress in reducing the costs of data collection, while improving information freshness through effective design and broadening itsscope by collecting more comprehensive data on forest resources and forest ecosystems. The presentation will highlight some of thesedevelopments of general interest to tackle the new challenges of climate change, bioeconomic transition and environmental monitoring: -The continuous design launched in 2005 in which the whole country is surveyed each year with annually updated results based on the last 5annual samples. Since 2015 the sample includes both remeasured and new plots for better efficiency (sample size x 2) and flexibility, whileretaining the advantages of fully permanent plots for change estimations. This continuous annual design with continuous partial replacement is offundamental importance for reducing costs and extending the scope from resources assessment to ecosystem monitoring. -The introduction in the 80's of an ecological and floristic survey which allows recently to show climate change impacts on the French forest floraand resulted in the possibility to develop (2011 - 2016) a habitat classification field protocol for forest plots. They have been all classified ashabitat for the first time in 2016, opening up the possibility of a habitat monitoring survey integrated into the NFI. -The innovative use of new technologies such as T-lidar scanning of inventory plots for a more complete assessment of tree volume and othernew variables (tree architecture, stand structure, etc.) ; and the in-lab measurement by CT scanner of the wood density of the about 30000 coresper year taken from the NFI sampled trees. This opens the prospect of an inventory of forests in biomass and carbon as accurate and detailed asis today the inventory of stem volume without significant cost increase.
