Study identifies key islands where stopping invasive species would have cumulative global benefits

Island-dwelling animals around the globe often face a common threat: alien species that compete with them for food, kill them and their young, and otherwise hamper their ability to survive. Now, new research shows that culling the non-native invaders on 169 islands around the world in the next decade or so could help save almost 10 percent of island animals at risk of extinction.

“Eradicating invasive mammals from islands is a powerful way to remove a key threat to island species and prevent extinctions and conserve biodiversity,” Nick Holmes, the study’s lead author the director of science at the biodiversity conservation nonprofit Island Conservation, said in a statement. “This study is an invaluable global assessment of where these future conservation opportunities exist and [it] supports regional and national decision-making about where and how to prevent extinctions.”
