                         Atlantic Forest biome is the reduction and fragmentation of forest 
                         areas, mainly by the change of land cover. So this research aims 
                         to conduct a survey of deforested areas in a sub-basin of Almada 
                         river watershed, Bahia. The review period is established for 
                         seventeen years, by analysis of Landsat satellite images 5TM 3,4,5 
                         RGB color combinations in the years 1989 and 2006. We applied the 
                         geometric correction, and then was classified by the supervised 
                         maximum likelihood method. Subsequently the image was 
                         reclassified, where classes were isolated area of forest in each 
                         period and later on the calculator tool in ArcGIS 9.3 raster file 
                         was obtained from the result of the deforested areas through the 
                         mathematical operation subtracting the forest class of 2006 by 
                         1989. From the calculations it was possible to observe an area of 
                         3216.98 ha of deforestation which accounts for 9.35% of the study
