ABSTRACT
Necromass is a crucial component for the forest structure. However, there are few studies of
necromass quantification in tropical rainforests and lack of efficient sampling methods. This
research aimed at verifying the accuracy and effectiveness of sampling methods (Line-intersect
sampling - LIS versus fixed area plots - FA) for the estimation of necromass in a tropical rainforest.
The accuracy and efficiency of the methods were evaluated through descriptive statistics, paired
t-test, ANOVA and relative efficiency. LIS method was more accurate and efficient, but it
requires high sampling to meet sample error of 15%. Necromass at the forest fragment studied
accounted for about 12.28% of the tree biomass. These findings show the importance of this
compartment inclusion when quantifying carbon stocks in humid tropical forests, which acts
as a true reservoir of carbon.
Keywords: sampling, fixed area, fallen dead wood, transect.
