[Eugenia cumini (L.) Druce]
|Java plum, jambolan
This large evergreen tree forms a dense cover, excluding all other species. The large black fruit are dispersed by frugivorous birds and perhaps occassionally by feral pigs (Sus scrofa). Although it is not an aggressive invader of undisturbed forest like the closely related roseapple, it prevents the reestablishment of native lowland forest. It is not really fire resistant, but fires are rarely intense enough in the stands to produce other than peripheral damage. This tree has not been evaluated for biological control.
It is found in dry to mesic and more rarely wet lowland areas up to 700 m on all major islands. There is a heavy infestation at Kalalau Valley, Kaua'i, and Kalaupapa, Moloka'i.
