WebJan 2, 2024 · Results. We estimate the total biomass of wild land mammals at ≈22 Mt wet weight (equivalent to ≈7 Mt dry weight or ≈3 Mt carbon content). Despite representing a small fraction of all land mammals species (6%), species with reported abundances constitute ≈55% of the total wild land mammal biomass (12 Mt vs. 22 Mt).
