Payments for carbon sequestration and storage services have emerged as a way to combat deforestation. Thus, the objective of this study was to evaluate the potential that a secondary forest remnant, located in the southeastern region of the state of Pará, has in receiving payments for environmental services for carbon sequestration and storage. To quantify carbon in the litter, collectors were installed in the forest remnant, for subsequent determination of the carbon content in the different components and to relate the production with the climatic variables. Carbon increment and carbon stored in the remnant were obtained through information collected from continuous forest inventory and using conversion factors available in the literature. From the average carbon content of each litter components and the stocked volume of the forest it was observed that the remnant has 25.45 Mg.ha-1 carbon stored in its living biomass and has a carbon increment of 1.98 Mg.ha-1 .year. The average carbon content of the litter components was 47.61%, with an annual carbon increment of 2.73 Mg.ha-1 , and a strong correlation between total litter production and temperature, rainfall and relative humidity. Based on the amounts paid per tonne of carbon sequestered, it was estimated that the studied forest remnant could receive € 859.56 ha, and this value could serve as an incentive for the conservation and maintenance of biodiversity at your opportunity cost.
