Erva-mate production and conservation of Araucaria Forest

open access: yes, 2015
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.
