About This Species

The Koala (Phascolarctos cinereus) is an iconic Australian marsupial currently listed as endangered in Eastern Australia. These stocky animals are characterised by their dense, woolly fur, which ranges from light grey in the northern parts of their range to brownish-grey in the south. Their underside is white, and they have a distinctive large, flat black nose. Northern Koalas are notably smaller than their southern counterparts, with Victorian males potentially reaching over 80cm in length and weighing up to 14kg. Their sharp claws are well-suited for climbing and serve as a defence mechanism.

Threats They Face

Despite being relatively common in some areas, Koalas face numerous threats that contribute to their endangered status:

  • Habitat Destruction: The clearing of eucalypt forests for agriculture, urban development, and other land uses is a significant threat to the Southern Stuttering Frog, leading to widespread habitat loss and fragmentation. As forests are cleared, the frogs lose essential shelter, breeding sites, and access to key food sources, such as insects and other invertebrates. This destruction forces populations into smaller, more isolated areas, making it harder for them to find mates and sustain healthy populations. Additionally, habitat fragmentation increases their exposure to predators and environmental stressors, further endangering the species. Without intervention, ongoing deforestation will continue to threaten their long-term survival.
  • Disease: Bacterial infections, particularly Chlamydia, pose a serious threat to the health of the species, often becoming more prevalent when populations are under stress due to habitat loss, food shortages, or overcrowding. Chlamydia infections can cause a range of debilitating symptoms, including respiratory issues, urinary tract infections, and, most notably, conjunctivitis, which can lead to severe eye inflammation and eventual blindness. Additionally, the species is vulnerable to retrovirus (RSV), which weakens the immune system and makes individuals more susceptible to secondary infections like Chlamydia. As habitat destruction forces animals into smaller, high-density areas, the risk of disease transmission increases, further endangering their survival.
  • Other Threats: Bushfires, drought, and vehicle collisions are significant threats to Koalas, leading to injury and mortality. The devastating 2019–2020 Australian bushfires, also known as Black Summer, destroyed millions of hectares of habitat, killing or displacing thousands of Koalas and drastically reducing their food sources. Severe drought conditions further weakened populations by limiting the availability of eucalyptus leaves, causing dehydration and malnutrition. Additionally, Koalas are highly vulnerable to vehicle collisions as they travel between fragmented habitats, particularly in urbanised areas. These combined threats highlight the urgent need for conservation efforts to protect Koalas and their dwindling habitats.

How Aussie Ark Is Helping

Aussie Ark is actively working to protect Koalas. Our efforts focus on:

  • Habitat Restoration and Protection: Aussie Ark has been dedicated to creating and maintaining sanctuaries for Koalas in areas of critical importance to their survival. These sanctuaries provide safe, protected environments where Koalas can thrive, free from the dangers of habitat loss, predators, and human interference. Within these carefully managed sanctuaries, native eucalyptus trees are preserved and restored, ensuring that Koalas have access to their essential food sources. By establishing these protected areas, Aussie Ark is not only supporting the current Koala population but also providing a foundation for future generations to flourish in a safe and sustainable environment.

  • Disease Free Insurance Population: Aussie Ark is committed to treating koalas and providing them with a safe, disease-free haven within the Barrington Wildlife Sanctuary. This protected environment ensures they receive the care and attention needed for their recovery and long-term survival.

  • Advocacy and Education: Aussie Ark plays a crucial role in raising public awareness about the many threats facing native wildlife, including Koalas. Through education and advocacy, they highlight the importance of conservation efforts and work tirelessly to encourage the protection of these iconic species. By engaging with local communities, stakeholders, and decision-makers, Aussie Ark strives to inspire collective action and ensure that vital habitats are preserved for future generations.
