Mimosa pigra (Giant Sensitive Tree) (pigra = lazy,slow), is an invasive species of the genus Mimosa, in the family Fabaceae. It is native to the Neotropics, but has been listed as one of the world's 100 worst invasive species, and has been documented in: Australia, Cambodia, Dominican Republic, Ghana, Guinea, Indonesia, Kenya, Malaysia, Mozambique, Papua New Guinea, South Africa, Sri Lanka, Swaziland, Tanzania, Thailand, Uganda, Zambia, United States, and Viet Nam (Vietnam). It forms dense, thorny impenetrable thickets particularly in wet areas.
In the late 1960s, small infestations of Mimosa pigra were identified along the banks of the Adelaide River in the Northern Territory, Australia. Action was taken by the N.T. Agriculture Branch to exterminate it by spraying with Tordon, which was promising to achieve eradication until the N.T government discontinued the work allowing the weed to spread widely and become the N.T's and possibly Australia's worst weed problem.[citation needed]
