abstract = "Forests in the south-west flank of the Amazon are known by
persistent dominance of Bamboos. It is still not well understood
how species of Bamboos interact with fire, but there is a strong
suggestion that fire favours the spread and colonization of
Bamboos species. On this work we aimed to compare burned and
unburned forested areas dominated by Bamboo through an analysis of
forest structure, spectral attributes and landscape pattern. Two
areas, burned in 2010 and unburned, were sampled with 0.25ha
inventory plots. Three plots were installed in each area, control
(PC) and burned (PQ). We obtained the NIR band, EVI and NDVI
indexes from a RapidEye image of 2012. The spectral attributes
were statistically different between PQ and PC, with higher values
for PC. The higher tree mortality in PQ area suggests lower amount
of NIR reflection, possibly associated to the higher occurrence of
tree crowns with no leaves. The Guido ToolBox software was used to
estimate the proportions of Bamboo, Forest and bare tree crowns in
each area, burned (Q) and non-burned (NQ). The proportion of bare
crowns mixed with forest was found to be more frequent on Q, as
the forest seems to be more heterogeneous. The NQ areas had
greater proportion of non-mixed forest and Bamboo mixed with
forest. The Contagion fragmentarion metric showed lower values of
fragmentation on NQ and higher values on Q. The results indicate
that fire may have favoured the expansion of Bamboo in Q area
leading to the higher fragmentation observed.",
