Additional Info

  • Where does this species come from?

    The pampas grass is native to South America

    Why is it a problem?

    Pampas threatens the productivity of plantation forests and land of high conservation value. It has the ability to reach distant open spaces quickly and to blanket them with very rapid growth. Native turfland communities can be quickly overcome by the invasion of pampas. Pampas invades disturbed areas such as cleared bush margins, burned areas and firebreaks where it competes with and smothers other vegetation, and provides habitat for rats and mice. The buildup of dry material from pampas such as dead leaves, leaf bases and flowering stalks creates a significant fire hazard.

    Means of reproduction?

    Pampas grass spreads by seed and by plant fragments.
