About the report
This review principally covers six tramp ant abatement projects funded in part by Caring for Our Country, namely the red imported fire ant (Solenopsis invicta) in southeast Queensland, electric ant (Wasmannia auropunctata) in northeast Queensland, yellow crazy ant (Anoplolepis gracilipes) in northeast Arnhem Land, Northern Territory and on Christmas Island, African big-headed ant (Pheidole megacephala) on Lord Howe Island, and Argentine ant (Linepithema humile) on Norfolk Island.
The review evaluates the management and control, impacts on biodiversity, and community engagement parts of these programs. In a concluding section we discuss where programs have been most effective in gaining biodiversity recovery, how this may be replicated across other tramp ants programs, and the degree to which the programs have been appropriate, effective, and efficient within their scope and area of attention to meet and contribute to reducing impacts on biodiversity, with particular emphasis on the programs' achievements, lessons learned, and overall legacy. This review also considers other infestations and other tramp ant species as potential candidates for abatement programs.
