(A) Percentage difference between biomass in regrowth forest (2010 values) and the biomass that would exist at that location if the forest was in equilibrium with the mean 1981–2010 forest disturbance rate, averaged over each forest type and based on LPJ-GUESS simulations forced by GFAD. (B) Total missing biomass carbon for each forest type, found by differencing the carbon densities of old-growth and regrowth stands in 2010 and multiplying by regrowth area, based on the CF simulation (dark green) and the FF simulation (light green). The symbols show sensitivity simulations, as in Fig. 2. Difference between CF and FF in A was minimal, and thus only CF is shown.
