Australia removed island rabbits in 1986; native habitat is returning
Phillip Island in Australia has seen a significant ecological recovery following the successful eradication of invasive rabbit populations in 1986. The removal of these pests allowed native vegetation and seabird colonies to naturally regenerate after decades of degradation.
Why it matters
It serves as a successful case study for conservationists on how targeted pest management can restore biodiversity in fragile island ecosystems.
Six kilometres south of Norfolk Island lies a striking volcanic island with red cliffs, where one of the Pacific's most impressive environmental recoveries is taking place.Phillip Island, part of Norfolk Island National Park, was left almost completely bare after 150 years of grazing by livestock and rabbits. Since a major pest eradication program ended in 1986, native plants and migratory seabird colonies have been steadily returning.The island's environmental decline began soon after European settlement in the late 18th century, when pigs, goats, and European rabbits were intentionally introduced as a live meat supply for the penal colony on nearby Norfolk Island.Uncontrolled grazing by these animals destroyed the island's fragile subtropical vegetation.
