Table 1. Data used to select potential areas for national forests. Regions of economically viable timber extraction, currently protected lands, nonforested lands, and occupied forest lands were delineated and used to define the possible regions for development. In the "Source" column below, IBGE stands for the Instituto Brasileiro de Geografia e Estatística, Imazon for the Instituto do Homem e Meio Ambiente da Amazônia, ISA for the Instituto Socioambiental, Radam for Projeto RadamBrasil, and INPE for the Instituto Nacional de Pesquisas Espacials.
