Trees and treelets species in gaps and light micro-sites in 5,12ha of Restinga Forest in Ilha do Cardoso, Sao Paulo State Tropical Forest dynamics studies elucidate the importance of knowledge about the relationship between light and distribuition of species to understanding the regeneration and diversity mainteinence of these communities. To contribute with this knowledge to Restinga Forest species this study described the distribuition of trees with dbh (diameter at breast high) ≥4,8cm in thirteen (13) indirect light categories, in 5,12ha of a Restinga Forest in Ilha do Cardoso, Cananeia Municipal District, Sao Paulo State. These categories correspond to different light micro-sites within the forest mosaic and are derived of the combination of the type or absence of covery where the individuals can be under of (under decidual trees, under evergreen trees or under intense light) and the position which each individual can ocupy within the forest (gap, understory, canopy). All the species were classified in ecological groups according to available literature into pioneers, early secondary, understory, climax and non-classified to correlation with their individuals distribuition within the light categories. There were sampled 7.277 tree specimens represented by 381 pioneers of 12 different species, 4.138 early secondary of 24 species, 48 understory of 2 species, 2.133 climax of 48 species and 577 non-classified specimens of 19 different species. Among the 105 species sampled, 35 presented preferential distribuition for some light micro-sites. These distribuition patterns suggest that the light quantity reaching the understory doesn’t restrict the occurence of pioneer species only to gaps. For some species the classification in ecological groups found in the literature were not coherent with the individuals distribuition and there were been suggested another classification according to its occurence in the Restinga Forest, which will be confirmed only through repetitions of this study among time. There were delimited 77 gaps in the study area during the classification in the indirect light categories, to which there were estimated area, shape, species and individuals compositions to assess the distribuition of species and ecological grups within these gaps and support comparisons with repeated studies in this area and with natural regeneration studies. Recurring studies using this method over the same spot during time or in different areas of the same Forest formation will provide data accumulation not only about the instantaneous distribuition of the specimens, but also about these forests dynamics, promoting the knowledge about the ecological bahaviour of species and about distribuition patterns of these species according to light regimes.
