             abstract = "The increasing anthropogenic pressure on coastal wetlands results 
                         in impacts that affect mangrove forest and their biodiversity. The 
                         Canan{\'e}ia-Iguape Coastal System is considered the most 
                         conserved coastal zone in S{\~a}o Paulo state. Despite this, an 
                         artificial channel carries about 60 % of freshwater from the 
                         Ribeira River to the coastal system resulting in a direct 
                         influence on the flora composition and sediment dynamics in the 
                         Iguape region. This paper aims to develop mangrove forests 
                         multi-temporal analysis, using 1997 and 2010 images, in Iguape 
                         region, South coast of S{\~a}o Paulo state, to assist the local 
                         coastal management. Digital processing techniques, including 
                         segmentation by region growing, and Battacharya supervised 
                         classification were applied to TM/Landsat5, using SPRING GIS, 
                         version 5.1.6. The map, from 1997, indicated the total mangrove 
                         area with 827 ha and aquatic macrophytes with 226 ha. Macrophytes 
                         were absent into the coastal system, in 1997. The results from 
                         2010 showed an increase of 125ha of mangrove areas and the 
                         occurrence of macrophytes into the coastal system, totalizing 
                         respectively 952 ha and 329 ha. Between 1997 and 2010, variations 
                         in the coastal system salinity caused changes in the areas 
                         suitable for mangrove forests habitat. However, the increase in 
                         mangrove area can mask the degradation of the site. This process 
                         is named cryptic ecological degradation. These changes must be 
                         carefully monitored to ensure biological and socioeconomic 
                         sustainability. This study can be used as a base for monitoring 
                         and management mangroves areas in the Canan{\'e}ia-Iguape Coastal 
                         System.",
