Diversidade florística em fitofisionomias de duas Unidades de Conservação na Amazônia Oriental, Pará, Brasil.

Abstract

The metropolitan region of Belém in the state of Pará has few urban parks, the most important of which are Utinga State Park (PEUt) and the Belém State Environmental Protection Area (APA Belém). Most botanical studies in these conservation units did not take into account the structure and floristic patterns between the phytophysiognomies. The objective of this work was to carry out a floristic inventory to compare the abundance of individuals and the richness and composition of species between phytophysiognomies. Inventory data was collected in 2018 and 2019 in Campinarana, terra firma forest, igapó forest and floodplain forest. 1.085 individuals were recorded, in 57 families and 162 species. There was significant variation in the number of individuals and species between phytophysiognomies. Campinarana had a lower abundance of individuals and species. There was a clear separation of species composition. There is variation in beta diversity (habitats) between types of vegetation and this must be considered in the management actions of these units in order to protect the majority of the flora.
