Tropical forests are important regulators of the flux and storage of carbon, water, and energy in the Biosphere, and they are the habitat of more than three-fourths of the world’s plant and animal species.

Large-scale impoverishment of Amazonian forests by logging and fire

Large-scale impoverishment of Amazonian forests by logging and fire

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.
