DIAMETRIC GROWTH MODELS OF AMAZON TREE SPECIES
Amazon Biome, Forest Restoration, Regression Models, Growth Equations
The Amazon biome has an extension of approximately 6 million km², where about 16 thousand species of trees are distributed, highlighting its importance. Moreover, a total of 3.9 x 1011 individual trees and an average density of 565 trees / ha are estimated. However, the scarcity of information on the growth of tree species in this tropical environment poses several challenges for forest management and restoration. One of the greatest challenges is related to forest restoration programs, which are not yet based on information on growth and adaptation in species selection, either due to lack of information or the choice of methods that are not feasible for the Amazon context. In this sense, the objective of this work is to model the growth in diameter for Amazonian tree species, which occur in permanent plots in the municipalities of Marabá, Peixe-boi and in the district of Porto de Trombetas. Through Regression techniques in permanent plots inventories in phytophysiognomies in these municipalities with 8, 9 and 17 years of measurements, respectively, obtaining the growth rate. The significance level will be determined by Student's T statistics and Snedecor's F statistics. With this rate, one can estimate the probable value of the diameter of each forest species for future periods.
