Resumo	(*)(?)	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.
