  1. MFD minimum felling diameter; cycle = cutting cycle; SM Schöngart (2008) method; Rot.pop. = biological rotation age of the population; CAIv pop. = maximum current annual increment of the population; Legisl. = Normative Instruction parameters (Brasil 2006); Inc. = simulated mean annual volumetric increment; Vol. (m3 100 ha−1) = total volume produced in a 100-ha area, during the cutting cycle length. The highest simulated annual increments in volume are presented in bold
