%X This study was lead in an area located in the of Lagoon of the Confusion-TO city, Tocantins State, with the objective to evaluate the natural regeneration of last the 50 years of the natural forest fragments, called regionally of ipucas, with the use of System of Geographic Information - SIG. For accomplishment of this study o was used softwares IDRISI Kilimanjar, ArcGIS 9,0, Cartlinx 2,1 and SPRING 4.2, as well as air photographs of 1956 and images of satellites TM/Landsat- 5 of 1984, ETM/Landsat 7 of 1998 and CCD/CBERS-2 of 2005. The identification of natural regeneration occurred with the use of two methods: through the quantification of the area of the fragments of each year and through function CROSSTAB of the IDRISI Killimanjaro. The methods had demonstrated that 1998 were the year where bigger natural regeneration occurred; corresponding 2657,07ha (48.15%). Although the suppression suffered for the natural forest fragments ipucas with the implantation of the hidroagrícolas projects, can be confirmed its advance on bioma Closed through the process of natural regeneration.
