abstract = "The surface-area-to-volume ratio (SAV) is a signifcant parameter
in vegetation description, although diferent researchers have
presented diverging estimates for forest litter. However,
considering litter as a unique entity and disregarding the SAV of
its components provides a misleading fre rate of spread.
Undoubtedly, the leaves are more relevant than the twigs for the
rate of spread of surface fres, as the former has a higher SAV.
Therefore, based on the proven hyperdominance of tree species in
the Brazilian rainforest, this work presents an accurate method to
estimate the SAV. Furthermore, it demonstrates the critical role
played by the SAV in the litter fammability and fre rate of spread
assessments and shows that the leaf moisture content does not
infuence its SAV. Besides, comparing SAV data using the
methodology presented herein with other authors assessments, the
results difer by up to 49%. Finally, using the Brazilian
rainforest litter in the methodologies of two distinct authors
showed a diference of at least 36% in the results. The primary
outcome of this study is the estimation of the SAV of leaves and
thin, medium, and thick twigs, representative of the Brazilian
rainforest, at 12,680 m\−1, 1360 m\−1, 620
m\−1, and 310 m\−1, respectively. The estimated SAV
values are essential input data to numerical simulation models,
and for comparison purposes with other authors work, the litter
SAV is 8460 m\−1.",
