text:  Disturbance has been implicated in the formation of vegetation dominated by large <unk> species . In seasonally dry Amazonian forests the density of large adult A. <unk> palms was correlated with canopy openness ; the species also dominates savannas formed by repeated forest fires in Trinidad and Tobago . <unk> speciosa forms pure stands in many parts of Brazil where natural forest vegetation has been cleared . Similarly , stands of A. <unk> in Bahia , 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 .
