Estoque de carbono como indicador de serviços ecossistêmicos na Mata Atlântica em Sergipe

Abstract

The ecological economy is an opportunity to assess the “climate regulating ecosystem goods and services” of the Atlantic Forest's native forests, and the carbon stocks in these native forests can be treated as a good indicator of the quality of ecosystem services as a mechanism for control and mitigation in preservation and conservation. The main objective is the evaluation of the relationship between species diversity and biomass, as well as the monetary quantification of the carbon stock in a remnant plant community of the Atlantic Forest in Sergipe. Three forests with different regeneration processes were analyzed, considering the phytosociological parameters of richness and biomass. Sampling of 30 randomly distributed plots of 10x10 m2 was used to estimate the aboveground and belowground carbon stocks from allometric equations. The results, however, refuted the hypothesis of correlation between richness and carbon stock. The results were significant for the differences in biomass between the forests, and showed us that the degrees of conservation of these environments influenced the greater biomass. Based on the carbon stock analysis, he estimated an average of 30.09 tons per hectare and an estimated average value of 5.747.40 reais/hectares in carbon credits. In this study, we conclude that the increase in species diversity or mature forests there is no increase in their biomass, but in areas in more advanced succession there was an increase in the carbon stock biomass, although it did not show high richness. We argue that the idea of a sustainable market brings other aspects and incentives for behavioral change with the possibility of including other ecosystem services associated with biodiversity and other functions such as water, pollination, production of native seeds and including cultural services.
