Estudos florísticos e fitossociológicos em comunidades vegetais de restinga da Ilha do Cardoso, Cananéia, SP.
Abstract
The present study evolved floristic composition, structure and regeneration dynamic
aspects of a restinga forest (pluvial sand coastal plain forest), at Ilha do Cardoso, in
Cananéia region, São Paulo State, Brazil. Three portions of restinga forest with
same physiognomic aspects were selected: restinga of Trilha para o Morro das
Almas (MA), Trilha Interpretativa (TI) and Estrada para a Captação (EC). Five
strata of forest were sampled in each portion: Tree, Tree/shrub, Shrub/herbaceous,
Herbaceous and Lianas. Each portion was analyzed individually and subsequently
were analyzed the entirely of the three portions and compared them. At Trilha para
o Morro das Almas were sampled 73 species, at Trilha Interpretativa 72, at
Estrada para a Captação 56 and totally sample 112, inside them 31 species were
common to three portions and 46 restrict only one of them. The three portions of a
forest were floristically similar, MA and TI had the highest Sørensen similarity
(70,3%), and TI and EC had the less Sørensen similarity (55,5%). When compared
the strata in general Tree/shrub and Shrub/herbaceous strata had the highest value
of Sørensen similarity, and the Tree and Herbaceous strata had the less similarity.
The highest diversity and equability were found in herbaceous strata, and the less in
tree strata. The plants of the three portions had majority of species with geographic
distribution in south and southeast Brazil regions, and the majority individuals and
species were secondary-climax category. The portions of studied forest were in
advanced stage of regeneration, and shade-tolerant species were favored. The
differences between three portions of a forest were due to natural process common
in tropical forests, where the substitution of one tree produce a mosaic of distinct
regenerative phases at community that differ in structure and floristic composition.
Differences in environment physical conditions, especially edaphic factors, and
distinct anthropic interventions are responsible too.
