The largest remaining marsupial carnivore in Australia

Population 14,000
30% decline over the last 25 years

Distinguished as the largest predatory marsupial on mainland Australia, it embodies a unique blend of agility, prowess, and adaptability. With its striking spotted coat and formidable hunting skills, the Tiger Quoll is a captivating symbol of Australia’s rich biodiversity. However, beneath its fierce exterior lies a struggle for survival, as this remarkable species faces mounting threats that have placed it in the category of endangered animals.

Solitary by nature and primarily nocturnal, Tiger Quolls lead a reclusive life, with their activities spanning the twilight hours when the forest comes alive with the sounds of nocturnal creatures. Although they are predominantly ground-dwellers, utilizing the dense underbrush and forest floor to hunt and move, Tiger Quolls are also adept climbers and swimmers. This versatility allows them to exploit a variety of ecological niches, from hunting small to medium-sized mammals, birds, and reptiles to scavenging for carrion.

Despite their adaptability and hunting acumen, Tiger Quolls are increasingly vulnerable to a host of human-induced challenges. Habitat loss and fragmentation stand as the most pressing threats to their survival, with expansive tracts of their natural habitats being cleared for agriculture, urban development, and mining. This encroachment not only diminishes their living and hunting grounds but also isolates populations, impeding genetic exchange and increasing vulnerability to diseases.

Competition with introduced species, such as foxes and feral cats, further exacerbates the plight of the Tiger Quoll. These invasive predators not only compete for food but also prey on the quolls themselves, particularly affecting the younger or smaller individuals. Additionally, diseases, both native and introduced, pose significant health threats to remaining populations, undermining conservation efforts and the species’ resilience.
