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