C stocks (a) and C density (b) in forest ecosystems in France from 1850 to 2015 as simulated by the CRAFT model (continuous lines) and as observed for some recent years (bars) by the IGN (2019) and RMQS. These simulations are obtained by considering France as a single region (see Data S2 for details on calculation). Net C sequestration in forest ecosystems including soil and biomass (c) and only forest biomass (d) in France as simulated by the bookkeeping model by Houghton; the static CRAFT (constant r and K parameters) and the CRAFT (dynamic time‐dependent r and K parameters)
