| Abstract | |
The Cananéi-Iguape lagoon system, in the south shore of São Paulo state, has the presence of the cordgrass Spartina alterniflora on the outer side of the mangroves. The cordgrass has a fundamental role in the fixation of sediments which will be the mangrove\'s propagation areas. Pioneers in the mangrove wetlands, Spartina holds and prepare the substrate for the mangrove seedling establishment. Mapping the presence of Spartina alterniflora in the islands Ilha de Cananéia and Ilha Comprida, allowed to identify the prone areas for its growth. The points of low energy in the river were more favorable to create banks of Spartina. The continuous exchange of sediments and nutrients which exists in a mangrove lagoon system, associated with the great ability of Spartina to capture and establishment, resulted in a study of connectivity between two islands.
