About the guide
Mimosa 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.
Mimosa forms dense stands that replace all native vegetation on the ecologically and economically valuable wetlands of the Top End of northern Australia. Mimosa invasion threatens the production, cultural and conservation values of wetlands, and reduces the scope for exploitation of resources by land users. Pastoralists are affected because the inedible and thorny mimosa smothers and replaces grasslands, blocks access to stock watering points and hinders mustering. Additionally, the harvesting of bush foods by indigenous people is hampered by mimosa.
In environmental terms, nationally and internationally significant wetlands are threatened by mimosa, which reduces the biodiversity of plant and animal life on the floodplains by outcompeting native plants and reducing available habitat for animals.
