Abstract

This study aims to characterize a native production area (native erval) through silvicultural procedures, productivity and density of Ilex paraguariensis St.-Hil. (erva-mate) and also the floristic, phytosociology, and diameter structure. To identify the silvicultural procedures, we used semi-structured interviews. For productivity assessment, the commercial biomass of I. paraguariensis was determined. For vegetation assessment, two permanent sample plots totaling 1.25 ha were installed, considering all individuals with circumference at 1.30 m above soil level (CBH) ≥ 31.4 cm, for which it was registered CBH, botanical identification, XY coordinates in the plot, and all the individuals of I. paraguariensis composing the production system. Silvicultural procedures were characterized by mowing, canopy opening and conduct of natural regeneration, promoting I. paraguariensis, Araucaria angustifolia (Bert.) Kuntze, and cattle. I. paraguariensis density was 634 trees.ha-1, with 2,030 kg.ha-1 of productivity in three-year crops. We found 22 species, with a predominance of Myrtaceae and Aquifoliaceae. The species of highest importance value and coverage was A. angustifolia. The diameter distribution showed a higher concentration of individuals in the smaller classes.
