Estimativa da biomassa e estoque de Carbono em Floresta Sazonalmente Seca no Semiárido brasileiro

Abstract

Researches that relates the quantification of Carbon stock (CO2) released to the atmosphere are countless. The study of carbon in Tropical Forest is carried out all over the globe, and trey are several present in Brazilian biomes. This study aims to quantify the carbon stock in the aerial biomass of the arboreal shrub strata in a tropical forest fragment that has been in the process of conservation for 32 years. For biomass estimation, a phytosociological survey was carried out and a biomass calculation was performed using an already established equation. 487 individuals belonging to 10 families and 18 different species were registered. Among the species with the greatest number within the area are Sebastiania macrocarpa, Bauhinia cheliantha and Piptadenia stipulacea. During the period there was a loss of biomass accumulation, and in the last year of study, there was a deficit of 313.16 kg of biomass. Three species had an increase in the carbon stock of Combretum leprosum, Croton adenocalyx and Piptadenia stipulacea, when presenting increases of 87.88 kg.ha-1, 92.76 kg.ha-1 and 18.18 kg.ha-1 respectively. We conclude that there is a need for a more time-consuming study in the area, especially in normal rainfall years. The species collected in the study should be better evaluated in relation to other tropical dry forest communities located in the same region of the respective studied area.
