    How does it spread?

    Fruits are spread by birds, other animals, water and human activities

    Why is it a problem?

    It competes with and replaces indigenous species. The abundant and prolific growth of this species at the expense of the native flora and fauna could have serious consequences for the preservation of biodiversity. Dense stands along watercourses are likely to reduce stream flow. Indigenous birds could neglect the dispersal of indigenous plants as a consequence of their preference for the fruits of this alien species. The effective seed dispersal by water enables this species to invade protected areas far from the parent plant
