Quantificação da biomassa e carbono em um reflorestamento localizado na APA do Pratigi – Ba

Abstract

Among the various environmental services provided by forests, carbon sequestration and storage stand out, due to the intensification of the greenhouse effect and the consequent global warming. Therefore, this work was carried out with the objective of evaluating plantations carried out with native species to verify the efficiency of the revegetation models implemented and quantify biomass and carbon for the purpose of obtaining carbon credits in the Pratigi APA. In the Pratigi APA, reforestation was carried out in 2010 in six different areas, which were inventoried to quantify biomass, using stratified random sampling. 24 permanent plots of 240 m2 (12 x 20 m) were allocated, considering a maximum error of 10% and α = 0.05. All individuals within the plots were measured for diameter at 1.30 m height (DBH), diameter at ground level (DAS) and height, and dead individuals were also observed. The plants measured were identified with aluminum platelets, samples of botanical material were collected for subsequent identification, the individuals were classified according to ecological groups and dispersion syndrome. The plant material collected, both from planted and regenerating individuals, was herbalized, screened and identified. Allometric equations used in tropical forests were applied together, accounting for an average amount of carbon in tons per hectare of 3.10 Mg ha-1, with an inventory error of 15.68%.
