DINÂMICA DE CRESCIMENTO EM UM FRAGMENTO DE FLORESTA OMBRÓFILA DENSA NO ESTADO DO PARÁ

Authors

Abstract

The high diversity of species in the Amazon provides a wide range of studies related to the dynamics of structural growth, with phytosociological studies that aim to describe the vegetation of this ecosystem being essential. This work aimed to analyze the horizontal structure and dynamics of the community and 5 species with the highest Importance Value Index (IVI). The study was carried out in a fragment of dense shoulder forest, in the municipality of Parauapebas- PA, where 100 plots of 10 m x 10 m were installed continuously in a transect of 20 m x 500 m. All individuals with DBH ≥ 10 cm were counted, measured and identified to species level. The families with the greatest richness were Fabaceae, Malvaceae, Urticaceae, Lauraceae and Anacardiaceae. Total density was concentrated in the smallest diameter classes in all years. The species that presented the highest IVI were Senegalia polyphylla, Tapirira guianensis, Cenostigma tocantinum, Ocotea nigrescens and Spondias mombin. Entrance rates were higher than mortality rates. Thus, the horizontal structure and entry and mortality rates followed a pattern expected from native forests.
