Why is it a problem?

Competes with and replaces indigenous species. Indigenous birds and monkeys could neglect the dispersal of indigenous plants as a consequence of their preference for the fruits of this alien species. Dense stands along watercourses and on the edges of wetlands are likely to consume large quantities of water. It is a host of fruit flies and invasive plants could act as a source of infestation of the flies to fruit orchards
