Priority Areas for Establishing National Forests in theBrazilian AmazonMark A. Cochrane 1,2 , Adalberto Veríssimo 1 , Carlos Souza Jr. 1 and Rodney Salomão 11 Instituto do Homem e Meio Ambiente da Amazônia (IMAZON), 2 Michigan StateUniversity, Basic Science and Remote Sensing Initiative (MSU/BSRSI)Brazil will benefit if it gains control of its vast Amazonian timber resources.Without immediate planning, the fate of much of the Amazon will be decided bypredatory and largely unregulated timber interests. Logging in the Amazon is a transientprocess of natural resource mining (Uhl et al. 1997). Older logging frontiers are beingexhausted of timber resources and will face severe wood shortages within 5 years(Veríssimo and Amaral 1998). The Brazilian Government can avoid continued repetitionof this process in frontier areas by establishing a network of National and State Forests(Flonas – Florestas Nacionais) to stabilize the timber industry and simultaneously protectlarge tracts of forest. Flonas currently comprise less than 2% of the Brazilian Amazon(83,000 km 2 ). If all of these forests were used for sustainable logging, they wouldprovide less than 10% of the demand for Amazonian timber. To sustainably supply thepresent and near-future demand for timber, approximately 700,000 km 2 of the Amazonforest needs to be brought into well managed production. Brazil’s National ForestProgram, launched in 2000, is designed to create at least 400,000 km 2 of new Flonas.Objective decision tools are needed to site these new national forests. We report here amethod for optimally locating the needed Flonas that incorporates information onexisting protected areas, current vegetation cover, areas of human occupation, and timberstocks. The method combines these information in a spatial database that allows formodeling of the economic potential of the region’s various forests as a function of theiraccessibility and timber values while constraining model solutions for existing areas ofprotection or human occupation. Our results indicate that 1.15 million km 2 of forests(23% of the Brazilian Amazon) could be established as Flonas in a manner that willpromote sustainable forest management while acting as buffer zones for fully protectedareas (Parks and Reserves).
