Abstract. Algorithms relating remotely sensed woody cover to biomass are often the basis
for large-scale inventories of aboveground carbon stocks. However, these algorithms are
commonly applied in a generic fashion without consideration of disturbances that might alter
vegetation structure. We compared field and remote sensing estimates of woody biomass on
savannas with contrasting disturbance (fire) histories and assessed potential errors in
estimating woody biomass from cover without considering fire history. Field surveys
quantified multilayer cover (MLC) of woody and succulent plants on sites experiencing
