<br/><br/> <br/><br/>Abstract<br/><br/>The aim of this study was to quantify the aboveground biomass and organic carbon of Araucaria angustifolia (Bertol.)<br/>Kuntze in a Mixed Ombrophilous Montane Forest in the state of Paraná. The aboveground biomass determination<br/>was carried out according to the direct method, using 29 trees with Diameter at Breast Height (DBH) ≥ 40 cm. The<br/>trees were felled, cubed and weighed by compartments, which were sampled for determining moisture and carbon<br/>content. The average aerial biomass and carbon were 2,126.5 kg ind-1 and 935.8 kg ind-1, respectively. The moisture<br/>content resulted in a mean individual accumulation of 2,376.6 liters ind-1 of water. Age did not necessarily result in<br/>higher volume production but resulted in higher stem biomass production. Organic carbon accumulation by native<br/>A. angustifolia trees should support carbon credits as an incentive for the conservation of araucaria and Mixed<br/>Ombrophilous Forest fragments.<br/><br/>Keywords: carbon credit, carbon sequestration, Mixed Ombrophilous Forest.
