Timber is a strategic resource in Amazon frontier development, providing 250,000 jobs and up to one-fourth of the region’s gross domestic product (Uhl et al. 1997; Veríssimo et al. 2002a, 2002b). Since the 1980s, timber sales have replaced government subsidies as the main economic force behind frontier expansion, financing roads deep into forest wilderness areas and providing funds to invest in forest clear-cutting and pasture formation (Mattos & Uhl 1994; Nepstad et al. in press). Timber obtained through contracts with individual property owners, large and small, accounts for most of the annual roundwood production. Unfortunately, most of the benefits of these agreements have accrued to loggers rather than landowners, and predatory logging practices have led to forest degradation. If properly managed, however, these accords could significantly reduce the expansion of logging activities into the region’s large blocks of sparsely inhabited forests and could provide a strong incentive for landholders to conserve and manage their private forest holdings. But this opportunity will be missed if the new Brazilian government’s forest policy proposal concentrates on government-administered timber concessions in an expanding network of publicly owned forests, as proposed by the previous administration.

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.
