Habitat/ecology:  "Forests and forest gaps, disturbed sites.  The tree is an early successional, light demanding, fast growing species that colonizes tree-fall gaps of rainforests in the native range.  The tree quickly occupies gaps and forms dense stands.  It sprouts easily after damage"  (Weber, 2003; p. 90).

Widely established in the forests to several hundred meters elevation on Tahiti and Raiatea (Welsh, 1998; p. 137).

Propagation:  Seeds are dispersed by frugivorous birds and bats  (Weber, 2003; p. 90).
