Caracterização estrutural do barbatimão (stryphnodendron adstringens (Mart.) coville) no cerrado do norte de Minas Gerais

Abstract

This study aimed to characterize of the Stryphnodendron adstringens (Mart.) Coville population to verify the viability of sustainable management in area of Savanna in the north of state Minas Gerais, Brazil country. Therefore inventoried 25 plots of 400 square meters in two places, in all was inventoried one hectare in each places. Was measured all adults individuals with diameter at breast height the 1,30 meter (DBH) ≤ 3 centimeter of barbatimão. In these plots was measured the diameter (DBH) and height (H) and subsequently for each site was evaluated: the De Liocourt quotient (q), basal area (G) and vertical stratification. The outcome showed a density of 180 and 218, mean diameters of 7,38 and 6,26 meters, mean of ‘q’ of 2,22 and 1,50 and means heights of 2,93 and 3,10 meters in two site respectively. The quotient’ De Liocourt showed imbalance in the recruitment in some classes of Site two. Although the imbalance indicated by ‘q’, the diameter distribution behaved exponentially negative as expected for native forests in the process of secondary succession. The Observed a more concentration of individuals in the middle stratum with 142 and 154 individuals in each site respectively. The conclusion this work that is although the species has distinct structure, on both sites studied the population of the barbatimão is constituted for a great number of diameter small individuals and with exclusivity of middle vertical stratum. The regenerative capacity of the specie, density height of the individuals per hectare and the horizontal and vertical structure show that there is viability to manage of the barbatimão on both sites since that their structures is maintained balanced.
