How many dunnarts are left in the world?
The Kangaroo Island dunnart is listed as Critically Endangered by International Union for Conservation of Nature (IUCN). The population was believed to be less than 500 before the 2019–2020 Australian bushfires. Following the fires, it is believed that only about 50 individuals exist.
Are fat-tailed Dunnart nocturnal?
Diet. The fat-tailed dunnart is nocturnal and mainly feeds on small invertebrates such as beetles, spiders, slaters, worms and slugs. Body fat is stored in the tail when food is plentiful, giving the tail a swollen appearance. This helps the individual to survive when food is in short supply.
Is Kangaroo Island protected?
The Western River Refuge, an Australian Wildlife Conservancy (AWC), Kangaroo Island Land for Wildlife (KI LfW) and private landholder jointly managed property, now protects over 369 hectares of critical habitat for threatened species.
How did the Kangaroo Island Dunnart survive the bushfires?
Pat Hodgens from Kangaroo Island Land for Wildlife said the organisation was able to find surviving dunnarts in “little small bits of unburned vegetation”. The remaining dunnarts were even more vulnerable to predation by feral cats, which were able to hunt more effectively in the burnt environment.
Is a Dunnart a mouse?
Dunnarts may look like mice but are not actually rodents at all. Dunnarts belong to a group called dasyurids, which are native Australian marsupial mammals.

Their eyes and ears are large, the snout is pointed and the tail is thick. During periods of abundant food, they store fat in their tails for a short time, due to which their tails become swollen, becoming thinner during the winter. These fat stores allow dunnarts to survive food shortages.
