Abstract
Ecologists have long sought to understand the factors controlling the structure of savanna
vegetation. Using data from 2154 sites in savannas across Africa, Australia, and South America,
we found that increasing moisture availability drives increases in fire and tree basal area, whereas
fire reduces tree basal area. However, among continents, the magnitude of these effects varied
substantially, so that a single model cannot adequately represent savanna woody biomass
across these regions. Historical and environmental differences drive the regional variation in
the functional relationships between woody vegetation, fire, and climate. These same differences
will determine the regional responses of vegetation to future climates, with implications for
global carbon stocks.
