Rewilding Visayan wildlife has turned a quiet corner of the Philippines into one of the world’s most promising wildlife recovery stories, with five once-vanishing species now breeding successfully in the wild.
Rewilding Visayan wildlife started small in 2010. Fernando Gutierrez and Pavel Hospodarsky founded the Talarak Foundation in Kabankalan City, on Negros Island in the Visayan region in central Philippines. Gutierrez, a longtime wildlife lover, offered his own land to build a breeding center for animals disappearing from the island’s forests.
Negros Island sits in the West Visayas, a region of lowland forests, mangroves, and coral reefs. Deforestation over the past century wiped out most of the island’s original tree cover. That loss pushed several native species to the edge of extinction within two human generations.
Talarak focused on five animals it calls the West Visayan Big 5. Each plays a distinct role in the forest ecosystem, acting as what scientists call an ecosystem engineer, a species that shapes its habitat for the benefit of others.
The list includes the Visayan Spotted Deer, the Visayan Warty Pig, the Visayan Tarictic Hornbill, the Negros Bleeding Heart Dove, and the Rufous-headed Hornbill. The foundation takes its name from the local word for the Rufous-headed Hornbill, its flagship species.
The Negros Bleeding Heart Dove is easy to overlook next to its larger companions. This ground-foraging bird gets its name from a splash of red plumage on its chest that looks like an open wound. Habitat loss and trapping pushed it to near extinction, making its recovery one of the program’s quieter triumphs.
Breeding the Rufous-headed Hornbill proved especially hard. Female hornbills seal themselves inside tree cavities for up to 105 days to lay and incubate eggs, relying entirely on their mate for food. In 2019, Talarak achieved the first successful captive breeding of the species in nine years.
By 2020, the foundation had bred all five species and begun returning them to protected forest as part of its rewilding Visayan wildlife program. Their main release site is the Bayawan Nature Reserve, 300 hectares of secondary forest run jointly with the Bayawan City government in Negros Oriental. Secondary forest is land that was once cleared or logged and has since regrown naturally, giving these species room to reestablish themselves.

The results of this rewilding Visayan wildlife effort have exceeded expectations. Wild populations of all five species are now considered thriving, and researchers are documenting behaviors never recorded before, even in captivity.
Visayan Warty Pigs, for instance, have been seen building shelters to escape rain and heat. That makes them the only wild pig species known to use tools this way, a discovery that surprised scientists studying the reserve.
Just as important, second-generation animals born in the wild show far less comfort around humans than their captive-born parents. That shift away from human familiarity matters enormously for long-term survival, since tame animals face greater risk from poachers and accidents.
None of this happened without local communities. Elders in villages near the reserve remember when these animals still roamed nearby forests decades ago. Watching them return has shifted how residents see local wildlife.
Many communities once viewed animals like the warty pig or spotted deer as prey. That view is shifting toward stewardship and pride, according to conservationists working alongside Talarak. The foundation aims to hand full management of the reserve to these communities by 2035.
Talarak’s ambitions extend beyond the reserve’s current boundaries. The foundation is planning a wildlife corridor linking Bayawan Nature Reserve to remaining primary forest in southwest Negros, extending its rewilding work for Visayan wildlife into new territory. That connection would let reintroduced animals mix with any surviving wild populations, strengthening genetic diversity.
The foundation has also learned that rewilding works best as a combined effort. Restoring native plants alongside animals lets each support the other. Trees offer shelter and food, while animals disperse seeds and keep vegetation healthy through grazing and foraging.
Talarak now manages a second site, the 1,000-hectare Upper Caliban-Imbang Watershed near Bacolod City, where local groups benefit from government conservation programs. The foundation also runs the Negros Forest Park, a breeding and education center that introduces visitors and students to the island’s endangered wildlife.
International partners have taken notice. The Global Rewilding Alliance welcomed Talarak as a partner in 2026, and the UK-based Synchronicity Earth has funded the foundation’s work since 2019 through its Asian Species Programme.
Rewilding Visayan wildlife shows what patient, community-rooted conservation can accomplish. A handful of animals bred on one man’s private land now roam wild forest again, watched over by the very communities that once hunted them. Negros Island offers a working example other tropical islands facing similar biodiversity loss might choose to follow.
