Prickly acacia
Released/reviewed: 2003
At present over 6.6 million ha of arid and semi-arid Queensland are infested with prickly acacia, mainly in the Mitchell Grass Downs.
Prickly acacia could potentially infest vast tracts of grasslands and woodlands throughout Australia.
The economic impacts of prickly acacia on Queensland’s grazing industry are estimated at $5 million per year.
Even at medium densities, it halves the primary productivity of grasslands, interferes with stock mustering and restricts stock access to water.
Control costs considerably outweigh its benefits as a shade tree and drought fodder.
