Abstract

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