As Earth Day approaches, Island Conservation will share stories of hope and success in conservation.
Six hundred miles north of Santiago, Chile, you’ll find Choros and Chañaral Islands, which are two of three islands that make up the Humboldt Penguin National Reserve.
These unique desert islands not only host a wide variety of threatened native Chilean plant species but were once home to over 100,000 pairs of Endangered Peruvian Diving-petrel and 80% of the world’s Vulnerable Humboldt Penguin population.
For millennia, the seabirds and sensitive desert plants thrived together in the Humboldt Penguin National Reserve. This all changed early in the 20th century when the European rabbit was introduced to the islands. Invasive rabbits stripped bare the herbs and shrubs, occupied diving-petrel nests, and devoured the cactus species that provided shaded nest sites for penguin chicks. When the invasive rabbits moved in, the native seabirds lost their homes.
In 2013, the Chilean National Forestry Corporation (CONAF), in collaboration with Island Conservation, removed invasive rabbits from Choros Island followed by Chañaral Island in 2016.
An important element for the successful confirmation of the project was the participation of Finn, a trained Labrador Retriever, who has contributed to several conservation projects around the world. Finn’s role was to confirm the successful removal of the rabbits from Choros Island.
In just under two years of intensive ecological restoration, conservationists redirected two extinction-bound Chilean seabirds toward recovery. CONAF and Island Conservation successfully removed the introduced, damaging rabbit population that was destroying native vegetation and fragile nesting habitat for the Humboldt Penguin and Peruvian Diving-petrel.
This marks the first protected area of its kind within the Chilean Protected Areas Network (SNASPE) to be declared free of invasive vertebrate pest species, an achievement that benefits native wildlife and the eco-tourism industry centered around them.
