RESUMO:

Growth rates are important for estimating future diameters, and understanding forest dynamics. Even though there are several studies on increment in diameter, those that cover long periods of time to offer species growth equations are rare. In this sense, this study aimed to determine the diametric growth equations for 81 Amazon forest species, in addition to calculating the value of these species as a function of these rates and the stored carbon stock. For this, a long-term inventory database with 60 years of monitoring (1956-2016) was used, which generated the estimates of the geometric rate of specie's diameter's growth with a regression model, after which these data were used in the calculations. The valuation of forest assets in conjunction with aerial biomass and carbon credit traded in the form of a commodity on exchanges. The model parameters were significant and showed R2 above 0.7, except for three species, the average curves adequately represented the growth behavior of the species and also a good precision in the projected data for future periods, the 81 species value was equivalent at EUR 70,016.39. Thus, this model represents an important step towards understanding the variations in species growth rates and how each species behaves over time, in addition to being able to use this data to calculate the carbon valuation eliminating the discontinuity of the timber production flow for considering the time horizon as a whole.
