[edit] Distribution and habitat

Typically found on 8000 km² in the Mitchel Grass downs of riparian grassland's, between Julia creek and Richmond in Queensland, it possibly occurs in the Mitchell Plateau of Western Australia. The Prickly Acacia is a threat to its habitat as it kills native grasslands. Cutivation and introduced species als threatens this dasyurid's habitat.

[edit] Social organisation and breeding

During the dry season, it shelters in cracks in the ground; in the wet season it shelters under vegetation. This nocturnal animal doesn't drink often as all the water it needs is in the food. Gestation is for 12 days with an average of 8 young born. Males are independent in 210 days and females in 168 days. A 4mm long joey can breath through its skin.

[edit] Diet

Insects and small vertebrates make up the majority of this species diet.

[edit] Status

The Julia Creek Dunnart is currently listed as an endangered species. This is likely due to the invasion of prickly acacia plants and introduced predators such as cats and foxes.
