                         of the most preserved remnants of Atlantic Forest. Several physics 
                         and histories factors allowed the conservation of these remnants 
                         in this region. The topography, low soil fertility and water 
                         regime stand out as great allies for preservation of natural 
                         vegetation, in addition to the creation of Conservation Units. 
                         However, studies have pointed deforestation history in those 
                         protection areas. In order to relate the responsible processes for 
                         land-use changes, sensing remote techniques have been used in 
                         intention to investigate forest cover changes association. This 
                         work claimed to identify and map regeneration and deforestation

                         serie from 1985 to 2017, comparing the results related to all 
                         region. Considering the forests covers distribution in 
                         Conservation Units, the forestall regeneration represented about 
                         30% of total net gain, while the deforestation process was 
                         approximately 22% from 1985 to 2017. With exception of APA

                         zero deforestation. On the other hand, those areas were the same 
                         that forest gain calculated by regeneration were the biggest. 
                         Concludes that the creation of Conservation Units is important

                         S{\~a}o Paulo e Paran{\'a},det{\'e}m cerca de 80% dos 
                         remanescentes cont{\'{\i}}nuos de Mata Atl{\^a}ntica.Diversos 
                         fatores f{\'{\i}}sicos e hist{\'o}ricos permitiram a 
                         conserva{\c{c}}{\~a}o desses remanescentes na regi{\~a}o. 
                         Destacam-se entre eles a topografia, baixa fertilidade dos solos e 
                         o regime h{\'{\i}}drico como substanciais para 
                         preserva{\c{c}}{\~a}o da vegeta{\c{c}}{\~a}o natural, 
                         al{\'e}m da cria{\c{c}}{\~a}o de Unidades de

                         utilizam-se t{\'e}cnicas de sensoriamento remoto no intuito de

                         a regenera{\c{c}}{\~a}o florestal representou cerca de 30% do 
                         ganho l{\'{\i}}quido florestaltotal, enquanto o processo de 
                         desmatamento foi em torno de 22%. Com exce{\c{c}}{\~a}o de
