Large-mammal biomass in Gorongosa, Mozambique, fell by more than 90% during the war and has largely returned, a 2019 study reports. The share of elephant, hippo and buffalo fell from 89% to 23%, so the recovery is uneven across species.

    Biomass, root-to-shoot ratio, carbon fraction
    Biomass is the dry weight of living plants per hectare. The root-to-shoot ratio adds the weight of roots. The carbon fraction is the share of that weight that is carbon, about 47% in tropical forests.
