Análise fitossociológica da formação "campo de mosaico" da restinga da praia do Crispim, Marapanim-Pa.

Abstract

The phytosociological analysis was carried out in a formation provisionally called "Mosaic Field", because it is a countryside community composed of herbaceous vegetation with sparse bushes and trees. In the herbaceous vegetation, the species with the highest Value of Importance Indices (VII) were: Rhynchospora canaliculata Boeck, Syngonanthus fertilis Rubl, Rhynchospora barbata (Vah l.) Boeck and Lagenocarpus rigidus Nees. This vegetation is considered homogenous because it has a low diversity of families and species; only 13 families and 22 species were recorded in 100 m2. In the bushes the diversity of species is even lower, only four families and four species. Of these species, two presented high IVls, Humiria balsamifera St. Hill. and Clusia grandifolia Splitz.
