A landmark United Nations report has revealed the devastating global impact of invasive alien species, identifying them as a major driver of biodiversity loss and extinctions. Released by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), the report highlights that invasive species have contributed to 60% of global extinctions and continue to threaten ecosystems worldwide.

Australia and Aotearoa New Zealand, among the hardest-hit regions, suffer from foxes, fire ants, possums, and deadly plant diseases, costing A$24.5 billion annually. The report stresses that prevention, biosecurity policies, and regional cooperation are crucial in mitigating threats and protecting economies, biodiversity, and cultural heritage.

While invasive species worsen environmental disasters, effective management strategies, government-industry partnerships, and public awareness can reduce their impact. Strengthened policies and investments are vital to counter rising biosecurity threats, ensuring sustainable environmental and agricultural protection for future generations.
