DIISE Database

Welcome to the Database of Island Invasive Species Eradications (DIISE), a new tool for conservation practitioners

The database can be viewed here: DIISE DATABASE

Islands are the epicenter of the current extinction crisis and invasive vertebrates are a leading cause of extinctions on islands. However, protection of threatened biodiversity by removing invasive vertebrates from islands is becoming a powerful and widely used conservation tool.

The DIISE is a publicly available resource to help land managers and conservation practitioners learn more about invasive vertebrate eradications on islands around the world. The database provides detailed information on individual eradication projects and also provides opportunities to analyze trends in past eradication projects. To date, we are aware of more than 1200 attempts to remove invasive vertebrates from islands. Of more than 1000 that are classified as successful or failed (and excluding reinvasions), the success rate is ~87%.

As we learn more about where this conservation intervention has been utilized, we expect to update these numbers. We encourage you to review the database and submit edits to existing data or new projects not currently in the database. Details on how to submit comments are provided on the DIISE website, DIISE DATABASE

The DIISE is a collaborative partnership comprising Island Conservation, the IUCN SSC Invasive Species Specialist Group, the Coastal Conservation Action Lab at the University of California, Santa Cruz, Maanaki Whenua-Landcare Research, and the University of Auckland, New Zealand.
