We estimated aboveground biomass using two allometric
equations; the moist forest equation for montane vegetation
and the dry forest equation for miombo (Chave et al. 2005).
We used wood basic density (g/cm3 at 12% moisture content)
values from our field estimates and values from the literature
for the same species or mean values for the genera or family
in case of missing data from the field estimates (Carsan
et al. 2012). Biomass values were aggregated into total carbon
density (AGC per hectare) at plot level, where 50% of
the biomass was assumed to be carbon.
