TONIATO, MARIA TERESA ZUGLIANI; LEITAO FILHO, HERMÓGENES DE FREITAS  and  RODRIGUES, RICARDO RIBEIRO. Fitossociologia de um remanescente de floresta higrófila (mata de brejo) em Campinas, SP. Rev. bras. Bot. [online]. 1998, vol.21, n.2, pp.197-210. ISSN 0100-8404.

The phytosociological structure was studied in two hygrophillous forest (swamp forest) fragments, in Campinas, state of São Paulo, Brazil. Ten plots of 10 m x 10 m were stablished in each fragment and all individuals with PBH (perimeter at breast height) ³ 10 cm were included. The data of both fragments were analised together. It was sampled 955 individuals from 55 species, 44 genera and 29 families. A low species diversity was observed (H’ = 2.80 nats/individual). The most important species, in terms of descending order of IVI, were Calophyllum brasiliensis (Clusiaceae), Protium almecega (Burseraceae), Styrax pohlii (Styracaceae), Syagrus romanzoffiana (Arecaceae), Talauma ovata (Magnoliaceae), Geonoma brevispatha (Arecaceae), Trichilia pallida (Meliaceae), Inga luschnathiana (Mimosaceae), Guarea macrophylla (Meliaceae) and Tapirira guianensis (Anacardiaceae), represented by many individuals. The richest families in species were: Myrtaceae (9 species), Lauraceae (6), Meliaceae (5), Euphorbiaceae (4) and Fabaceae (3). These forests are restrict to permanently flooded soil and display a peculiar forest pattern, with characteristic floristics, structure and physiognomy that distinguish them from other forests of the state of São Paulo.
