Addressing invasive alien species

Invasive alien species – animals and plants that have been deliberately or accidentally introduced by humans around the world – are spreading and pose a major threat to biodiversity, particularly birds. Evaluating the most appropriate responses requires a detailed understanding of which alien species are causing the greatest problems, and where. Fortunately, considerable advances in technology and techniques mean that invasive alien vertebrates (cats, rats, goats, pigs etc.) can now be eradicated even from quite large islands. BirdLife, working alongside collaborating organisations, is pioneering efforts to identify where across the world are the most significant priorities for eradications. These focus our action on the ground through BirdLife’s Invasive Species Programme
