Parkinsonia (Parkinsonia aculeata) is one of northern Australia's worst weeds. It is a thorny shrub or small tree that forms thickets primarily along and in water bodies. Current infestations cover over 800,000 hectares. Most of the semi-arid to subhumid tropical areas in Australia are climatically suitable for Parkinsonia. There is an urgency to prevent the weed from spreading further into important areas of conservation value such as the Lake Eyre and Murray-Darling basins, Cape York, areas in Queensland and southern regions of Australia, as well as to minimise impacts of existing infestations across northern Australia. The strategy outlines a management system based on a zonal system. Zones will be based on catchments and will be used to prioritise the actions required for this species.
