Phytosociological structure and dendrometric aspects of agroforestry systems in the Southwest of Paraná-Brazil

Abstract

Agroforestry systems (SAF) are an alternative to conventional agricultural systems, aiming to reconcile the production of food and forest resources with ecosystem services. The objective of this work was to evaluate the phytosociological and dendrometric structure of the tree species that comprise three SAF in the Southwest region of Paraná. The survey was carried out after approximately two years of implementation, with quantitative and qualitative variables being measured. The floristic composition of the three SAF showed the occurrence of 35 species, 29 genera and 19 families. The SAF showed significant diversity (H’ = 2.20) and evenness (J = 0.6198). Musa ssp, was highlighted with the highest number of individuals (density), highest basal area (AB), highest importance value index (IVI) and cover value index (IVC). The vast majority of species cultivated in the SAF, evaluated in this work, have fruit production as their main objective and, to a lesser extent, wood production. Cinnamomum zeylanicum, Nectandra lanceolata and Araucaria angustifolia, which are recommended for the enrichment of SAF.
