Estrutura da comunidade arbórea em sistemas agroflorestais na Zona da Mata Rondoniense

Currently, a phytosociology is based on understanding the dynamics of tropical forests, determiningsuccessional trends in ecosystems. Among agroecosystems with tropical forests,agroforestry systems are alternatives to family agriculture, reconciling forest conservation andhuman communities. The objective of this study was to evaluate a floristic and phytosociologicalcomposition of two agroforestry systems in Zona da Mata Rondoniense. Frequency,dominance, importance value index, cover value, mean tree height, Shannon diversity index,and Pielou equability were evaluated. A total of 1,343 individuals belonging to 31 species weresampled. The diversity obtained in SAF A was 0.80 and in SAF B it was 0.77. Both systemspresented Pielou equability equal to 0.12, demonstrating low values of diversity and equability,reflecting the predominance of Hevea brasiliensis and Theobroma grandiflorum.
