About the guide
Parkinsonia is a Weed of National Significance. It is regarded as one of the worst weeds in Australia because of its invasiveness, potential for spread, and economic and environmental impacts.
Parkinsonia threatens rangelands and wetlands around Australia. If left untreated, it displaces native vegetation and reduces access to land and waterways.
Economic costs to landholders stem from an increased difficulty in mustering stock, a reduction in stock access to watering points and a decrease in primary production of grasses that are replaced by parkinsonia. Additionally, parkinsonia infestations provide refuges for feral animals, especially pigs.
The environmental impacts of parkinsonia are numerous. Native plant species are replaced, leading to lower quality habitat for animals. Wetlands are particularly vulnerable because parkinsonia can dam watercourses, cause erosion, lower watertables and take over vast tracts of floodplain. Threatened areas include national parks and other regions of high aesthetic, indigenous and tourist value.
