According to a recent study published by the journal PLOS ONE, eradicating invasive mammals from islands could save over 9% of the world’s island vertebrates in danger of extinction. Eradicating invasive species, particularly cats and rats, is an effective conservation tool – “more than 1,200 invasive mammal eradications have been attempted on islands worldwide, with an average success rate of 85%” on native species recovery.

Invasive species are the second greatest cause of plant and animal species loss globally. Their impact on islands is particularly threatening, due to the highest concentration of both biodiversity and species extinctions in these regions. Although representing just over 5% of Earth’s territories, islands have been the habitat of approximately 75% of extinct species since 1500 (Tershy et al. 2015).
