Phytosociological analysis of the tree component of three agroforestry systems in the Mid-South Region of Paraná, Brazil

Abstract

This study evaluates the floristic composition and phytosociological structure of three agroforestry systems located in the municipalities of Laranjeiras do Sul and Rio Bonito do Iguaçu, inserted in the Atlantic Forest Biome. We selected tree elements with a circumference at breast height (CAP) above 10 cm. The analysis includes the history of each area, the management adopted and the analysis of parameters such as absolute and relative density, absolute and relative dominance, and cover value index, as well as the evaluation of the threat status of each species. A total of 456 trees were analyzed, comprising 52 species, 44 genera and 24 families. All agroforests showed good representation in numbers of individuals and species, proving the efficiency of the managed areas in reconciling food production and conservation of native biodiversity.
