Wetlands, including mangroves, perform diverse functions, besides the production of goods and services on an ecosystem and landscape scale. The combination of functions, goods and ecological services has a fundamental importance for society. The study of physiographic types is intended to help in dealing with and understanding the function of a complex system. Complex systems are those that share four attributes: diversity of constituents, interdependence between parts, connectedness and adaptation. This study was carried out in the Cananéia region, located in the southern coast of the São Paulo State (25°S), Brazil. Data from the 1980’s to 2009 on the structural development of mangrove forests of two physiographic types, fringe and basin, were analyzed to discern patterns of spatial and structural organization. The fringe forests studied in the region presented a predominance of Rhizophora mangle and high structural development due to the high inundation frequency in depositionally stable sites. Fringe forests, located in progradation areas with low tidal energy, were dominated by Laguncularia racemosa with low structural development. The basin forests are dominated by R. mangle or L. racemosa, presenting reduced structural development in function of the lower inundation frequency, a predominantly sandy substrate and low salinity. But some basin forests dominated by Avicennia schaueriana were better developed reflecting the growth characteristic of this species. The results shown here highlight the large variations in the quality and intensity of forcing functions and the structural and functional diversity allowed by the plasticity of the species involved and their capacity to interact and adjust to the environment in which they develop.
