RESUMO:

Studies on dynamics are important for us to understand the characteristics and structure of a plant community. The forest dynamics is a process by which the forest remains balanced, contributing with important characteristics of the plant community maintaining the structure and composition over the years. The current state of a forest environment is resulting from the interactions of various processes, growth, mortality and the regeneration. This work aimed to evaluate the composition, structure and dynamics of the arboreal component in areas of forest formation in two hectares in the Serra das Araras Ecological Station (Esec da Serra das Araras. Data from two censuses (2016 and 2019) were used, in two parcels 100 X 100 m permanent standings designated ESA-02 and ESA-03. The criterion of inclusion was a diameter ≥ 10 cm at a height of 1.30 m from the ground. the descriptors phytosociologicals used were: relative density, relative frequency, relative dominance and importance value. For floristic diversity, Shannon-Wiener (H’) and Pielou (J’) were used. to compare the data of diameter, height, basal area and number of trees between the censuses we used t-test. For this community, the succession classes were analyzed. ecological. In 2016, 694 individuals, 109 species, 79 were cataloged. genera and 39 families. In 2019 in the same areas 614 individuals, 104 species, 78 genera and 38 families. The diametric structure of the ESA-02 is more heterogeneous than ESA-03. In the basal area for ESA-02 and ESA-03 there was an average gain of one census to another. Mortality occurred in individuals who presented larger diameter. The present study allows us to infer that the forest remains balanced, contributing important characteristics of the plant community maintaining the structure and composition over the years and keeping the current state of a forest environment that results from the interactions of several processes in particular growth, plant mortality.
