Estrutura vertical de sistemas agroflorestais em Rolim de Moura, Zona da Mata Rondoniense

Agroforestry systems (AFS) are land use and management systems that associate tree specieswith croplands and/or animals, combining conservation of natural resources with agriculturalproduction. The study of vertical stratification is fundamental to assess performance andindicate management practices. In this sense, this study aimed to analyze the vertical structureof two agroforestry systems in Rolim de Moura, Rondonia Forest Zone. Therefore, it was carriedout the stratification of the tree component into three strata and then the values for density,frequency and basal area were calculated. In the two agroecosystems, the medium stratumshowed the highest values for density and basal area. Cupuacu tree (Theobroma grandiflorum)was the species with highest densities in the medium and lower strata, whereas the rubber treepredominated in the upper stratum.
