In just under two years of intensive ecological restoration, conservationists redirected two extinction-bound Chilean seabirds toward recovery. Chile’s National Forestry Corporation (CONAF) and Island Conservation successfully removed the introduced, damaging (invasive) European rabbit population that was destroying native vegetation and fragile nesting habitat for the IUCN Vulnerable Humboldt Penguin and IUCN Endangered Peruvian Diving-petrel on two islands of the Humboldt Penguin National Reserve.
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.
The return of these islands to the conditions needed to support seabird nesting not only stands to prevent the extinction of the Vulnerable Humboldt Penguin and Endangered Peruvian Diving-petrel, but also supports Chile’s biodiversity goals and builds momentum in the movement toward global environmental health, as well as improving eco-tourism opportunities for local communities,” says Aarón Cavieres, executive director at CONAF.
Cause for Alarm
The islands of Choros, Damas, and Chañaral, which make up the Humboldt Penguin National Reserve, bathe in the productive, nutrient-rich waters of the Humboldt Current System. They are home to 80% of the world’s Vulnerable Humboldt Penguin (Spheniscus humboldti) population and were once home to 100,000 pairs of Endangered Peruvian Diving-petrel (Pelecanoides garnotii).
The reserve is a cornerstone of a growing eco-tourism industry built by nearby fishing communities,” says Cavieres. “Eco-tourism, driven by the unique wildlife of the Humboldt Current System, offers a sustainable future for the region’s native plant and animal species as well as the local communities.”
For millennia, the region’s seabirds and sensitive desert plants thrived together, but everything changed early in the 20th century when the European Rabbit was introduced to Choros and Chañaral islands. Invasive rabbits denuded the islands of shrubs and delicate herbaceous plants, occupied diving-petrel nests, and ate the cactus species that provided shaded nest sites for penguin chicks. In addition to the many threats these seabird species face at sea, the loss of breeding habitat put these birds at risk of extinction and threatened to compromise a budding eco-tourism industry centered around seabird and marine mammal observation.
In 2013, CONAF, in collaboration with Island Conservation, took the first step toward meaningful intervention in the Reserve. To restore the conditions needed to support native species and the eco-tourism industry built around them, the partners removed invasive rabbits from Choros Island and declared the project a success one year later in 2014.
Island Conservation Project Manager Madeleine Pott commented, “The results of the restoration on Choros Island were almost immediately evident across the island. We saw fields of seedlings, hillsides covered in the threatened flower Alstroemeria philippii, and Peruvian Diving-petrels looking to nest in burrows that had been taken over by rabbits.”
An important element for the successful confirmation of the project was the participation of a trained dog in the detection of invasive rabbits. Finn is a Labrador Retriever, trained in New Zealand, who has contributed to several conservation projects around the world. Finn played an important role in confirming the successful removal of invasive rabbits from Choros Island.
The success on Choros paved the way for a similar intervention in 2016 on Chañaral Island, which is two-thirds bigger than Choros. A team of 30 people conducted fieldwork over a 20-month period, covering over 6,680 kilometers; they braved the harsh desert sun and the powerful southern winds that rip up from the Antarctic to complete the project.
After months of monitoring Chañaral for signs of remaining rabbits, the island and the entire reserve—the first protected area of its kind within the Chilean Protected Areas Network (SNASPE)—have been declared free of invasive vertebrate pest species. Scientists have already spotted signs of a healthy ecosystem resurging: barren landscapes have been replaced by fields of flowers and 16 species of plants never before recorded on the island have been identified – including three species never seen before in the Reserve.
As native plant and wildlife populations bounce back, the nearby fishing communities look forward to increased eco-tourism opportunities, which center on the vibrant marine and terrestrial communities of the Reserve.
The rebounding vegetation and wildlife of Choros and Chañaral demonstrate the power of invasive species removal,” says Pott. “The restoration of the Humboldt Penguin National Reserve offers hope for continued conservation success in the region and around the world. CONAF’s commitment to protecting native Chilean species positions them to achieve AICHI biodiversity targets, specifically targets 5, 9, and 12.”
Building on this success, CONAF and Island Conservation are looking to restore other islands in Chile with high biodiversity benefits, including Alejandro Selkirk Island in the Juan Fernández Archipelago.
About the partners
Chile’s National Forestry Corporation (CONAF) is a private law entity under the Ministry of Agriculture, whose main task is to administer Chile’s forestry policy and promote the development of the sector. The Corporation is headed by an executive director, currently Mr. Aarón Cavieres Cancino, and has the mission to “Contribute to the sustainable management of native forests, xerophytic formations and forest plantations through the functions of promotion, oversight of forestry legislation- environmental protection and the protection of vegetational resources, as well as the conservation of biological diversity through the National System of Protected Wild Areas, for the benefit of society. ”
Island Conservation (IC) is our world’s only global, not-for-profit conservation organization whose mission is to prevent extinctions by removing invasive species from islands. We work where the concentration of both biodiversity and species extinction is greatest – islands. Removing a primary threat – introduced invasive vertebrates – is one of the most critical interventions for saving threatened plants and animals and restoring island ecosystems. Once invasive species are removed, native island species and ecosystems can recover, often with little additional intervention. Since 1994, IC and partners have successfully restored 60 islands worldwide, benefiting 1090 populations of 399 species and subspecies. IC is headquartered in Santa Cruz, CA with field offices in Australia, the Bahamas, British Columbia, Chile, Ecuador, Hawai’i, New Zealand, Palau, and Puerto Rico.
About the Reserve
The Humboldt Penguin National Reserve is situated 600km (372.8 miles) north of Santiago, Chile. The Reserve is managed and protected by CONAF.
New research reveals that nearly half the earth’s highly threatened vertebrates live on islands and are endangered by invasive species. By removing or controlling invasive species on these islands, we can protect 41% of all threatened vertebrates worldwide and 95% of threatened island species.
Once introduced to islands, invasive mammals represent key threats to native species through predation, competition, and habitat loss. Invasive species are implicated in 86% of all island plant and vertebrate extinctions. The removal of invasive species from island ecosystems is a proven way to protect biodiversity and prevent extinctions. Nearly 900 successful invasive species removal projects have been carried out on islands across the globe. When it comes to island conservation, every local success fits into the global project to save species from extinction.
