Figure 1
Observed and simulated 2018 demographic profile for the mature even aged spruce stand in Harwood Forest. Panels (a) and (b) respectively, show the Cumulative Density Function across tree mass from the truncation mass for the stand density and stand carbon stock. Panel (c) shows the distribution of trees across mass for JULES-RED and observations, where the observations have been binned into JULES-RED mass classes. Panel (d) shows the carbon distribution across the stand population or the ‘biomass inequality’ of the stand. The truncation mass (vertical dotted line) of 16.7 kgC is estimated by combining the minimum surveyed dbh of 7 cm with the allometric equations for estimating the tree carbon mass (see methods).
