Floreana, the most southerly island in the Galápagos, is home to many endemic species under threat from invasive predators.

Our work in the Galápagos began in 2004, when we collaborated with the Charles Darwin Foundation and Galápagos National Park to help prevent the extinction of the mangrove finch, which at the time was the Galápagos' rarest bird.

We're now working with Island Conservation (IC), Galápagos National Park and Galápagos Conservation Trust (GCT) on plans to eradicate invasive predators from Floreana, using our knowledge from previous eradication programmes on other islands. By removing invasive animals from Floreana, we hope endemic species like the Floreana mockingbird, Floreana tortoise and Galápagos racer can be reintroduced to the island.

Removing invasive predators

The presence of rats, mice and feral cats, which are all invasive predators of Floreana's endemic wildlife, threatens the island's ecosystem.
What we're doing to help
Alongside our partners, we have been working on plans to eradicate invasive predators from Floreana, which will allow native species to recover and thrive without the threat of predation from species that shouldn't be on the island.

Establishing a captive husbandry programme

To avoid the risk of losing any endemic populations during the eradication process, a selection of birds must be brought into captivity as a safety net population.
What we're doing to help
Using our expertise in the captive care of birds, we helped to build specialist aviaries in the Galápagos and designed a husbandry programme to safely house these threatened species while Floreana's invasive predators are removed. While the risk of losing bird populations during the eradication is low, having a safety net population means we'd have a population of healthy birds to reintroduce to the island if needed.
