Caracterização da vegetação da caatinga do sul do piauí para geração de energia

Abstract

The sustainable management of the savanna is fundamental to the preservation of this ecosystem and maintenance of rural populations. Thus, this study aimed to characterize the vegetation of an area of savanna located in southern Piauí, aiming its use for power generation. Thirty-two plots of 20 m x 20 m were deployed. Forest inventory of plots were performed for the quantification of biomass (branchless trunks) and characterization of vegetation. Seventy species, divided into nineteen families were identified. The amount of biomass produced in the area averaged 164 t/ha or 153 m3/h. The vegetation still had an average height of 5.6 m, with 4205 trees / ha. The forest has a high population density, with a predominance of individuals with small diameter (52% of the population between 2-5 cm in diameter). The largest amount of biomass is concentrated in the upper 10 cm diameter classes (84% of wet biomass). The high diametric diversity requires special treatment of biomass for power generation. In general, the amount of biomass generated in the study area is high, with great potential for power generation.
