                         forest clearing and slash burning and describes the structure and 
                         successional development of the secondary forest in the seasonally 
                         dry southern Amazon. The original burn study was conducted in four 
                         land clearings in 1997, 1998, and 1999. The size of the clearings 
                         varied from 1 to 9 ha. The native forest was felled, allowed to 
                         dry for approximately three months and then burned by the end of 
                         the dry season. A census was conducted in the central 1-ha forest 
                         on each site prior to the areas felling and burn. The aboveground 
                         biomass (AGB) and structure were similar to other primary tropical 
                         forests. However, the high density of Cecropia spp. before the 
                         forest felling and burn treatment indicates past low intensity 
                         disturbances. Seven and eight years after the fire, the fallow 
                         forests were still in an early successional stage dominated by 
                         Cecropia spp. The four areas had a high biomass accumulation 
                         during the studied period, varying from 7.5 to 15.0Mgha\−1 
                         year\−1. The lower biomass accumulation in one plot was an 
                         effect of a higher fire severity, produced by the one-year 
                         difference in time between slash and burn of the forest, slowing 
                         the natural regeneration of Cecropia spp. The time needed for this 
                         forest to recover to the pre-fire AGB levels ranged from 20 to 30 
                         years, assuming the current AGB accumulation rates are maintained. 
                         Considering these results, the maintenance of regenerating 
                         secondary forests in the Amazon would be a significant 
                         contribution to soil and watershed protection, minimizing 
                         biodiversity losses and perhaps mitigating climatic changes 
                         effects in the region.",
