 <unk> has been implicated in the formation of vegetation dominated by large <unk> species . In seasonally dry <unk> forests the density of large adult A. <unk> <unk> was correlated with canopy <unk> ; the species also dominates <unk> formed by repeated forest fires in Trinidad and <unk> . <unk> <unk> forms pure stands in many parts of Brazil where natural forest vegetation has been cleared . Similarly , stands of A. <unk> in <unk> , Brazil ( which are cultivated for <unk> fibre ) are managed using fire — the seedlings survive cutting and burning , and are able to dominate burned forest patches .
