Kangaroo Island Wildlife Thrives Thanks to Predator-Free Fence Initiative

Kangaroo Island’s wildlife is experiencing a remarkable recovery, thanks to an innovative predator-free fencing project. The initiative spans 380 hectares and was initiated by the Australian Wildlife Conservancy (AWC). It has been five years since the Western River Refuge was enclosed by a cat-proof fence. The results have been staggering, particularly for vulnerable species.

Kangaroo Island Dunnart’s Resurgence

The endangered Kangaroo Island dunnart has notably thrived within the refuge. AWC principal ecologist Pat Hodgens estimates that the population of these small nocturnal marsupials has surged by 90-100%. This increase highlights the refuge’s importance in protecting vulnerable species.

Tracking the Dunnart

Mr. Hodgens noted that the dunnart is difficult to survey due to its shy nature. Despite challenges, the consistent higher activity levels of dunnarts within the fence compared to outside are promising. This protection has allowed their numbers to grow significantly.

Return of Bird Species

Alongside the dunnart, other species such as the western whipbird and Bassian thrush have returned to the Western River Refuge. Their populations have also doubled since the project’s initiation. Before the enclosure, these birds had not been sighted for years, primarily due to predation from feral cats.

Impact of Bushfires

The 2020 bushfires devastated over 90% of habitats critical to these vulnerable species. With the loss of such extensive territory, native animals faced increased predation from feral cats. The rapid establishment of the cat-proof fence became not just an experiment but a necessary rescue operation for wildlife on Kangaroo Island.

Environmental Management and Indigenous Knowledge

Ngarrindjeri elder Mark Koolmatrie has expressed enthusiasm for the increasing wildlife numbers. He emphasizes the cultural significance of restoring native species and advocates for collaboration between the Ngarrindjeri People and other island residents. His vision includes integrating traditional land management practices with modern strategies to enhance ecological restoration.

Collaborative Conservation Efforts

• Protecting vulnerable species through a cat-proof fence
• Involving indigenous knowledge in restoration efforts
• Ensuring the health of ecosystems for future generations

The Western River Refuge initiative is a vital step towards ensuring the survival of Kangaroo Island’s unique wildlife. As recovery efforts continue, the hope is to maintain and bolster these populations for years to come.
