  • Introduced species have been the primary driver of documented bird extinctions. They are implicated in the decline of more than half of all threatened bird species
  • BirdLife Partners are designing, implementing and sharing techniques to control and eradicate invasive alien species at IBAs.
  • At least four bird species have been saved from extinction by Partner action against invasive species.

  • BirdLife's Pacific Partnership has cleared thirty islands of invasive rodents. Bird populations are recovering, and people are benefiting from increased crop yields and reduced disease risk. 

Invasive alien species are animals and plants that have been introduced into a natural habitat. In the last 500 years, species like rats, cats and mice have driven over 70 bird species to extinction. They remain one of the greatest of threats to our natural world. The BirdLife Invasive Alien Species Programme unites the world’s largest Partnership of national nongovernmental nature conservation organisations to tackle the global extinction crisis. From local to global, we are developing and sharing our expertise to tackle invasive alien species. We’re eradicating or controlling exotic species at sites where they constitute a major conservation problem, and implementing locally-led biosecurity measures to ensure they don’t return.

And together we’re calling for more effective national, regional and global policies to address nonnative invasives.
