Little natural regeneration of this species seen in Micronesia (Space & Falanru, 1999). Some naturalization noted, mostly on bare soil, on Mangaia, Cook Islands (Space & Flynn, 2002).

Observed on the Chuuk islands of Weno, Tol and Fefan; probably present on other islands as well (Space et al., 2000).

Planting of this species is prohibited in Miami-Dade County, Florida (U.S.) (Hunsberger, 2001).

Physical: Girdle, pull seedlings.

Chemical: Triclopyr herbicide mixed with an oil diluent (Randall et al., 1996; p. 24)
