In 2017-2018, we updated existing data in the database and added new eradication events. In 2019, following the publication of the proceedings of the international conference on island invasive in 2017, we conducted minor updates to existing data and added a small number of new eradication events. As of December 2019, the database contains over 2,000 eradication events, including over 500 eradications added during the updates. The number of completed mammalian eradications from islands (classified as whole island events, where data quality is good or satisfactory, and excluding domestic populations and reinvasion events), includes 1,550 events on 998 islands since 1872, with an 88% success rate. More than 60 countries and territories have attempted eradications.

Please see Spatz et al. (2022) for a global synthesis of over 100 years of invasive vertebrate eradications on islands, including summaries of area treated, methods, and outcomes by invasive vertebrate targeted which are among the most frequently requested statistics, as outlined in The global contribution of invasive vertebrate eradication as a key island restoration tool.

While we make every effort to maintain the data please note that errors or omissions may still occur. Please read our disclaimer and note we also attempt to score the data quality for each eradication event (definitions). Please see Holmes et al. (2019) for a review of how the database was collated, and recommendations for use of data, as outlined in Tracking invasive species eradications on islands at a global scale. Should you become aware of errors, omissions, or have additional information to contribute about eradication events, we encourage you to contact science@islandconservation.org.

The online Database of Island Invasive Species Eradications was built with the support of The David and Lucille Packard Foundation, the National Fish and Wildlife Foundation, and the Global Environment Facility.
