Island Conservation Impact Report 16/17 2017-12-13T19:07:50+00:00


Islands are biodiversity hotspots well known for their species richness. Island ecosystems are also among the more vulnerable environments on Earth and host 75% of all known animal extinctions.

New research in 2017 from Island Conservation scientists and partners reveals that nearly half of our world’s threatened vertebrates live on islands and are endangered by invasive species.

The good news? By removing or controlling invasive species on these islands, we can protect 41% of all threatened vertebrates worldwide and 95% of threatened island species.  

Invasive species are non-native and cause environmental, social, or economic harm when introduced to a region. On islands, the presence of invasive species is particularly problematic because the native plants and wildlife have often evolved without defenses against invasive impacts.

Because islands are isolated and surrounded by water, invasive species can quickly overwhelm and alter an island ecosystem. Invasive predators easily raid nests and prey on juvenile birds and reptiles, while invasive herbivores cause damage by overgrazing native vegetation and trampling sensitive habitat. Fortunately, on many islands, populations of invasive species can be completely removed. After the last invasive individual has been removed from an island, many plants and animals will begin to recover, and other key restoration activities can take place. Island restoration is one of those rare and refreshing conservation undertakings that can be declared successful with finality and clarity.

By working together, we can achieve remarkable conservation breakthroughs that prevent extinctions and allow native island plants and wildlife to thrive again. Since Island Conservation’s inception over 20 years ago, we’ve worked for this transformation on 60 islands.

Thanks to your support, that number continues to climb. With each passing year, we’re picking up speed in the race against extinction.

Every day we do our best to make the right choices for our planet. Yet, it’s easy to wonder if our choices are having a measurable impact. Will our efforts really make the world a better place for generations to come?

If there is one conservation action we can depend on for tangible change, it’s island restoration. Removing invasive species from islands works. It results in healthy ecosystems, reinvigorated livelihoods, and thriving native plants and animals.

This gives me hope.

Our 2016-2017 Impact Report highlights the tangible results achieved by our most recent island restoration projects. In 2017, we announced the successful restoration of seven islands in three different regions of the world. Desecheo Island, Puerto Rico is now ideally positioned to once again host large colonies of seabirds and native lizard species. Habitat for the Critically Endangered Polynesian Ground-dove and Endangered Tuamotu Sandpiper has doubled thanks to the restoration of five islands in the Acteon and Gambier archipelagos in French Polynesia. Critically Endangered juvenile Ricord’s Iguanas and Vulnerable Rhinoceros Iguanas are now scurrying about on Cabritos Island, Dominican Republic—a sight rarely seen when invasive species were present.

As we celebrate our successes, we continue to look forward and advance our work on Alejandro Selkirk Island in Chile, Floreana Island in the Galápagos, and more for 2018 and beyond.

Thank you to our donors, partners, and friends. You make our work possible. May you face each day hopeful for a future even brighter than imagined, knowing that you are a part of real change.



Island Conservation has successfully restored
60 islands worldwide, benefiting 1090 populations of 399 species and subspecies.

In 2017 islands across the globe benefitted from restoration efforts. The vibrance of the plants and wildlife of these islands serves as inspiration and hope as we continue forward in our mission to prevent extinctions.
