abstract = "The southwest Amazon forests are dominated of bamboo species of
the genus Guadua and cover about 161,500 km2. These individuals
have a life cycle of about 28 years and present only one
reproductive event followed by their death. This process
accumulates dry biomass in the forest and increases the
probability of fire occurrence. Since extreme drought events
increase fire vulnerability, and this region has been affected by
some of these events in the last decades, it is possible that
bamboos are related to a higher occurrence of forest fires. In
this sense, the objective of the present study was to evaluate the
detection of bamboo mortality in southwest Amazon forests using
MODIS (MAIAC) data, spectral mixture modeling and CART decision
tree. The combined use of band 5 (medium infrared) and GV fraction
allowed the detection of bamboo mortality with 56% accuracy. The
bamboo life stages can be differentiated because of different
spectral patterns, especially on the near and medium infrared
wavelengths, and distinct intra-annual seasonality patterns from
non-bamboo forest. It was possible to map the bamboo-dominated
forests, including bamboo life stages, and non-bamboo-dominated
forests with 76% accuracy. The mortality detected in this study
may have been influenced by the occurrence of fire.",
