                         fires that occurred in 2005 in the municipality of Boca do Acre, 
                         in the southern part of Brazils state Amazonas. Fire scars 
                         observed on Landsat satellite images TM 5 from 2004 to 2006 were 
                         visually interpreted and digitized and potential carbon emissions 
                         were estimated from the burn of forest biomass. Remote sensing 
                         techniques applied to satellite imagery allow identification and 
                         quantification of forest fire scars in Amazonia. Over 44 thousand 
                         hectares of forests affected by fire were mapped, the majority 
                         concentrated along the southern edge of the municipality (2.1% of 
                         total forest cover). Errors of omission and inclusion in the 
                         mapping were 4% and 0%, respectively. Total estimated loss of 
                         above-ground live biomass resulting from forest fires in 2005 was 
                         7.10 × 106 t. Consequently, 3.44 × 106 t of potential carbon 
                         emissions were committed from the initial burn of forest biomass 
                         and that killed by the fire, considering the oxidation of dead 
                         biomass by decomposition or through combustion in subsequent fire 
                         events. Our results indicate that forest fires can affect 
                         extensive tracts of forest and can emit significant amounts of 
                         carbon to the atmosphere in periods of extreme droughts. Fire 
                         plays a significant role as a threat to the biological balance of 
                         the forest. Fires cause loss of biomass and increase emissions of 
                         greenhouse gases. Fire impacts have critical implications for the 
                         future of forests in the Amazon.",
