For millions of years, plants and animals evolved in harmony with the natural world. This process was magnified on islands, where species developed specialized characteristics and unusual adaptations due to isolation and limited resources. Small mammals on islands often grew large and select large mammals grew small. Some birds became flightless and some species lost (or never developed) predator defense mechanisms. Biodiversity flourished, and islands became home to thousands of unique plant and animal species found nowhere else in the world. Sadly, this paradise would not last forever.

With the exploration of man came the spread of invasive species, damaging foreign interlopers. Invasive species introduced to islands devoured native wildlife or ate their food, destroying the balanced island ecosystems and pushing native species to extinction.

Islands are the site of 80% of all known animal extinctions, with invasive species as the primary cause. Yet islands are still home to almost half of all Critically Endangered plants and animals. Without intervention, our world is poised to lose these special island plants and animals.

Just as the threat of extinction is highest on islands, so are our opportunities to save species at risk. Thanks to you, our donors, partners, and friends, we can remove invasive species from islands to save plants and animals from extinction. It is because of your dedication to a world filled with healthy, thriving species that there is hope. By working together, island by island, we are bringing paradise back.


Greetings Friends of Island Conservation,

We are both honored and proud to be the newest leaders of Island Conservation! Each of us has been involved in biodiversity conservation for many years, yet leading this organization as the new CEO and board chair is energizing and exciting. We can say too that our transition has been smooth and efficient. Indeed, we have hit the ground running.

The things that inspire us to lead Island Conservation are our organization’s lasting, tangible results saving island species, our use of the best available science to make hard decisions, and as a result, our stellar reputation. In September at the World Conservation Congress in Honolulu, Hawaii, a senior executive of the US Fish & Wildlife Service called us a revered partner. In addition, we were asked by New Zealand’s Department of Conservation, the world leaders in island invasive species eradications, to help them with the ambitious Million Dollar Mouse operation on Antipodes Island. And in the tradition of fostering outstanding science, five of our conservation scientists and two of our founders were co-authors on a paper published in the Proceedings of the National Academy of Sciences, which was covered by the LA Times, National Geographic, and Newsweek. Finally, we had the honor of working with dozens of Pacific and Caribbean island nations to build capacity and expertise to protect island communities, plants, and animals from invasive species.

We are delighted to share these amazing stories of partnership, conservation hope, and success with you in this, our second online interactive Impact Report 2015-2016. We hope you’ll take a few minutes to read about the remarkable progress we have made and the inspiring collaborations in which we have taken part.

It is because of your support—our donors, partners, and friends—that we are confident in the continuing success of Island Conservation. There are many more endangered species on islands to be saved, and we are gearing up for yet another year of exciting conservation interventions. We are ever so grateful to all of you who believe in Island Conservation and make it possible for us to do what we do. We will be looking to you in the coming months and years for support and ideas as we continue to grow and evolve this terrific organization.

Thank you for being a champion for island species everywhere!

Island Conservation prevents extinctions by removing invasive species from islands. Working together with local communities, government management agencies, and conservation organizations, we select islands that have the greatest potential for preventing the extinction of globally threatened species; develop comprehensive and humane plans for the removal of invasive species; implement the removal of invasive species; and conduct research – conservation measures – to understand the ecosystem changes and benefits to inform future conservation action.

Island Conservation’s impact extends beyond our work on-the-ground. Our mission has reached people across the globe through science publications, press, animated film, and more. Read on to find out how Island Conservation’s work is catching and keeping the attention of scientists, editors, and ordinary people who care deeply about the natural world.

In order to protect native plants and animals on Lord Howe Island, Australia, invasive rats must be removed. But are we able to come together to make it happen?

Five years after the removal of invasive rats, conservationists return to Palmyra Atoll. Conservation Biologist Coral Wolf describes the vibrant scene today.

Island Foxes are no longer endangered thanks to action by dedicated conservation organizations, including Island Conservation’s work on San Nicolas Island.

Island Conservation’s former CEO Bill Waldman and board member Daniel Simberloff pen a compelling rebuttal in response to a New York Times’ piece that erroneously claims invasive species may not be harmful.

Part nature documentary, part fairy tale, and with blindingly beautiful animation, Bright Spots calls to prevent extinctions by removing invasive species from islands. Created by Jilli Rose and narrated by Island Conservation’s Director of Science Nick Holmes.

New global assessment published by scientist Holly Jones, Island Conservation’s Director of Science Nick Holmes, and co-authors finds major benefits to biodiversity when invasive mammals are removed from islands
