Above ground biomass (AGB in Mg ha-1) with regard to altitude.
AGB calculated using (a) the best height-diameter model per forest type, (b) the best height-diameter allometric model per plot, (c) Feldpausch et al. (2012) height-diameter allometric model for East Africa and (d) Feldpausch et al. (2012) height-diameter allometric model for Central Africa. p value and “r” of Pearson correlation between AGB and altitude are indicated in each plot. Significant correlations at p<0.01.
