Floristic Structure And Composition In An Area Of Dense Rainforest Under Forest Management
The purpose of this work is to deliver the phytosociology and floristicity of a fragment of Dense Ombrophilous Forest under forest management in the region of Portel, Pará. Four clusters were sampled, divided into secondary and terciarias plots totaling 80 sampling units of 0,4 hectares each. In which all tree individuals with diameter at breast height (DAP), at 1,30 m from ground level, above 10 cm were measured, in addition to performing phytothegic recognition and elaborating the calculations of the paramemers of equability and floristic similarity. A total of 1621 individuals were recorded, distributed in 35 families and 146 species. The families Fabaceae, Lecythidaceae and Sapotaceae were the ones with the highest IVIF and the highest representativeness of individuals. The species Eschweilera coriacea (DC.) S.A.Mori, Licania macrophylla Benth., Vouacapoua americana Aubl were the ones with the highest IVI. The mean Shannon variety index among the plots was 3,82 and the Pielou Equability index was 0,84, noting that the region has a high floristic variety and has great potential for forest management activities.
