Urgent Action Needed to Combat Invasive Alien Species Threatening Biodiversity

Introduction

Invasive alien species, long recognized as a significant threat to both nature and people, require immediate and decisive action. A team of 88 experts from 47 countries has underscored the urgency of addressing this global issue. Their critical evaluation, published in Nature Ecology & Evolution, emphasizes that curbing the threats posed by invasive alien species is both urgent and achievable¹.

Key Findings

• Magnitude of the Threat: The impacts of invasive alien species observed today may underestimate their future effects. These species are likely to continue expanding their geographic ranges, causing negative consequences for ecosystems and biodiversity¹.
• Interactions Among Biodiversity Drivers: Recognizing that no driver acts in isolation, understanding the interactions among various factors affecting biodiversity loss is crucial. Invasive species are part of a complex web of influences¹.

Collaborative Solutions to Alien Invasive Species

• Global Cooperation: The authors stress the need for collaboration, communication, and cooperation across borders and within countries. Addressing invasive alien species requires a coordinated effort on a global scale¹.
• Evidence-Based Approach: The Intergovernmental Science Policy Platform on Biodiversity and Ecosystem Services (IPBES) provides an evidence-base and actionable options for immediate and ongoing action. Researchers, policymakers, and practitioners must work together to implement effective strategies¹.

Conclusion

The threats posed by invasive alien species are expected to rise, with approximately two hundred new species introduced globally each year. Urgent action is essential to prevent, detect, and control these invaders at local and global levels. By prioritizing collaboration and evidence-based solutions, we can mitigate the impact of invasive species and protect our planet’s biodiversity¹.
