Amazonian deforestation rates are used to determine human effects on the global carbon cycle and to measure Brazil's progress in curbing forest impoverishment. But this widely used measure of tropical land use tells only part of the story. Here we present field surveys of wood mills and forest burning across Brazilian Amazonia which show that logging crews severely damage 10,000 to 15,000 km2 yr−1 of forest that are not included in deforestation mapping programmes.
Changes in weather and land use are transforming the spatial and temporal characteristics of fire regimes in Amazonia, with important effects on the functioning of dense (i.e., closed‐canopy), open‐canopy, and transitional forests across the Basin.
