RESUMO

Mangrove forests get developed in distinct patterns, depending on geomorphological and environmental scenarios. Its spatial and temporal development was studied in a landscape ecology context, at the Cananéia-Iguape Coastal System. Stand and Site hierarchical levels had been used to analyze mangrove forests. At Stand level, aerial photography processing along with Geographical Information System (GIS) showed distinct spatial variations during the same 16 years period (1981-1997) in the two case areas: Mar de Cananéia and Baia de Trapandé. At Site level, mangrove forests surrounding Mar de Cananéia and Baia de Trapandé had been monitored during 2 years (2002-2004) using fixed plots, providing information on its development. Gramineous Spartina alterniflora, pioneer species and determinative for propagule establishment, colonize at first emerged sandbanks. Studied mangrove forests surrounding Mar de Cananéia are, during initial and youth phases, dominated by Laguncularia racemosa, in deposition areas, as suggested in bibliography. At Baia de Trapandé surround, the dominant species was Rhizophora mangle. Mature forests are dominated by R. mangle or Avicennia schauerianna, depending on area’s characteristics. Studied mangrove forests follow model of succession seen in bibliography.
