Our world today is experiencing a major wave of species extinctions; some estimates are 1,000 times greater than historical rates. When we lose species, ecosystems unravel, and we see and feel the direct effects on our world, livelihoods, and well-being.

Islands represent the greatest concentration of both biodiversity and species extinctions. Island species are incredibly unique, yet they are highly vulnerable to novel disturbances. Invasive species are a leading cause of extinctions on islands and of biodiversity loss globally. As the threats of extinctions are highest on islands, so are our opportunities to save species at-risk. We will lose island species forever, unless we act to save them now.

We believe biodiversity conservation is essential for the well-being of all humanity. To us, safeguarding biodiversity means preventing extinctions, protecting ecosystems, and sustaining critical resources on which people and nature rely on.

We envision a future in which our world’s most at-risk island animals, plants, ecosystems, and communities are thriving, safeguarded from damaging invasive species and thus more resilient to other emergent conservation threats.

Removing a primary threat—introduced invasive vertebrates—is one of the most critical interventions for saving threatened plants and animals and restoring island ecosystems. This is why we partner with individuals like you and organizations to prevent extinctions by removing invasive species from islands.

On Guadalupe Island, Mexico, there are thirty-four plants found nowhere else on Earth—almost all of them endangered because feral goats decimated the landscape. The top of the island was once covered with forest, but by 1948, the forest was down to only 1 percent of its former extent. We first put up fences (pictured above) to exclude goats from certain areas, and the results were dramatic. In 2003, working with Grupo de Ecología y Conservación de Islas (GECI) and the local community, we removed feral goats entirely from the island. Within a few years, there were more than 10,000 pine seedlings, 120,000 cypress seedlings, and 770 seedlings of the island’s endemic palm. Additionally, six species thought to be extinct were rediscovered.
