Invasive Plants


 * Prickly Acacia (//Acacia nilotica//) is a small, thorny, shrub or spreading tree generally growing to about 4-7 m high, occasionally to 10 m. It is usually single stemmed. The deep taproot also has several branches near the surface.Although capable of regenerating from cut stumps, Prickly Acacia only reproduces by seeds. A healthy, medium-sized tree in a well watered environment can produce as many as 200 000 seeds per year.**


 * Prickly Acacia could potentially infest vast tracts of grasslands and woodlands throughout Australia**

Preventing spread is the most cost-effective way of managing Prickly Acacia.
