The brush-tailed bettong, a small marsupial resembling a miniature kangaroo, is making a remarkable comeback after facing near extinction. Known for its unique survival tactics, this species has captured the attention of conservationists worldwide.When threatened by predators, the brush-tailed bettong employs a startling strategy: it ejects its tiny joey from its pouch and bounces away in a different direction to evade capture.While this may seem harsh, it’s a crucial survival mechanism for a species that was once extinct in South Australia’s Yorke Peninsula.
Historically, brush-tailed bettongs, also called woylies, roamed across more than 60% of mainland australia. However, European colonization introduced feral cats and foxes, which decimated their populations. Additionally, the destruction of their native grassland and woodland habitats further pushed them to the brink. Between 1999 and 2010, their numbers declined by 90%, a catastrophic drop attributed to factors like the spread of blood parasites. Today, they occupy just 1% of their former range, confined to a few islands and isolated pockets in Southwestern Australia.
Efforts to revive the species are gaining momentum through initiatives like Marna Banggara, which aims to reintroduce brush-tailed bettongs to their native habitats. This project is part of a broader movement to restore Australia’s biodiversity and protect its unique wildlife.

Restoring Yorke Peninsula’s Ecological Diversity: The Return of the Brush-Tailed Bettong
The Yorke Peninsula in South Australia is witnessing a remarkable ecological revival, thanks to the Marna Banggara initiative. This ambitious project, launched in 2019 by the northern and Yorke Landscape Board, aims to restore the region’s historic biodiversity by reintroducing native species that have disappeared as European colonization.“We are on a mission, if you like, to bring back some of these native species that have gone missing in our landscape since European colonization,” says derek Sandow, project manager of marna Banggara. The initiative, formerly known as the Great southern Ark, was renamed to honor the Narungga peopel, the traditional custodians of the land.
“Marna in our language means good, prosperous, healthy, and Banggara means country,” explains Garry Goldsmith, a Narungga community member involved in the project.
A Safe Haven for the Brush-Tailed Bettong
The first species to be reintroduced is the brush-tailed bettong,known as yalgiri to the Narungga people. To create a safe environment for these marsupials, the team erected a 25-kilometer predator-control fence across the narrow part of the Yorke Peninsula. This fence encloses a 150,000-hectare area, effectively reducing the impact of invasive predators like foxes and cats.
“We’ve reduced fox and cat impacts to a level that’s low enough for these yalgiri to be reintroduced and for them to actually find refuges,find food,and to survive themselves,” says Sandow.
Between 2021 and 2023, nearly 200 brush-tailed bettongs were introduced to the protected area. These individuals were sourced from various remaining populations across Western Australia to “increase the genetic pool,” according to Goldsmith.
Sandow emphasizes the importance of this genetic diversity, stating that these individuals “hold the genetic footprint for the future of the species hear.”
The Role of Ecosystem Engineers
Brush-tailed bettongs are more than just a species in need of conservation—they are ecosystem engineers. These small marsupials play a crucial role in maintaining the health of their environment by dispersing seeds and aerating the soil through their foraging activities. Their reintroduction is expected to have a ripple effect, benefiting the entire ecosystem of the Yorke Peninsula.

A Collaborative Effort for a Healthier Future
The success of Marna Banggara is a testament to the power of collaboration between conservationists and Indigenous communities. By working together,the project not only aims to restore the Yorke Peninsula’s biodiversity but also to honor and integrate the cultural heritage of the Narungga people.
As the brush-tailed bettongs bounce back into their natural habitat, they symbolize hope for a healthier, more prosperous future for the land and its people.

The brush-tailed bettong, a small marsupial often referred to as “nature’s little gardeners,” is making a remarkable comeback in australia’s Yorke Peninsula. Thanks to a reintroduction program led by the Marna Banggara initiative, these ecosystem engineers are not only thriving but also considerably enhancing the health of their habitat.
The Role of Brush-Tailed Bettongs in Ecosystem Restoration
Brush-tailed bettongs,native to Australia,play a crucial role in maintaining soil health. They primarily feed on underground fungi, bulbs, seeds, and insects, but their most significant contribution lies in their digging behavior.“A single yalgiri can turn over two to six tons of soil per year,” says Derek Sandow, a key figure in the reintroduction program. This activity aerates the soil, improves water filtration, and aids in seedling germination, creating a ripple effect that benefits the entire ecosystem.
Their reintroduction to the Yorke peninsula is part of a broader effort to restore the region’s biodiversity. Historically, brush-tailed bettongs were widespread across southern Australia, but habitat loss and predation by introduced species led to their decline. By bringing them back, conservationists aim to revive the ecological balance.
Success Beyond Expectations
The reintroduction program has been a resounding success. “It’s probably even exceeding expectations,” Sandow notes. Recent monitoring surveys revealed that nearly 40% of the captured individuals are descendants of the original group introduced to the area. Even more promising, 22 of the 26 females surveyed were carrying pouch young, a clear indicator of a healthy and breeding population.
This success is a testament to the bettongs’ adaptability and the program’s meticulous planning. The Marna banggara team has worked tirelessly to ensure the marsupials’ survival, even transporting them by plane to their new home.
A Brighter Future for the Yorke Peninsula
The return of the brush-tailed bettong is a beacon of hope for conservation efforts in australia. Their presence not only signifies the recovery of a threatened species but also the restoration of a vital ecological process. As these “little gardeners” continue to thrive, they pave the way for other species to flourish in the rejuvenated landscape.
