Steve and Terri Irwin bought roughly 1,416 hectares of land in Blackbutt, Queensland, in 1994 and planted 44,000 eucalyptus trees as part of an effort to restore habitat for koalas, according to Australia Zoo.
The couple named the property Ironbark Station. It sits within the Great Dividing Range, a mountain range that runs along Australia's eastern coast and is considered an important region for koala conservation.
Steve and Terri Irwin led the restoration of the natural environment on the land. The eucalyptus trees they planted are essential to koalas both as a food source and as shelter within their habitat.
The project expanded in the years that followed as further land was acquired. The protected area eventually reached about 5,130 acres, or roughly 2,076 hectares. In 1999, a rehabilitation facility of about five acres was established on the property for native marsupials.
A strategy built on restoring habitat
The project rested on a core conservation principle: rescuing individual animals is not enough if the conditions of their surrounding environment keep deteriorating. Restoring vegetation and permanently protecting the land became a central part of the Ironbark Station effort.
Eucalyptus trees were central to that strategy. Koalas depend closely on them for both food and shelter, so restoring the vegetation also meant creating better conditions for koala populations to recover.
The work extended Steve Irwin's public profile beyond the persona he built on camera. The Australian naturalist became known worldwide through The Crocodile Hunter, but his career also included numerous wildlife conservation and protection projects.
A project that continued after Steve Irwin
Steve Irwin died in 2006, but his family has continued to be involved in wildlife conservation through Australia Zoo and related projects.
Terri, Bindi and Robert Irwin have maintained that connection to the zoo and to various initiatives aimed at protecting Australian wildlife. The project started decades earlier at Ironbark Station has become part of the conservation legacy associated with the Irwin family.
The Ironbark Station story shows that protecting a species does not depend only on rescuing animals, but also on conserving and restoring the places they need to survive.
