The New Holland Mouse is classified as extinct in seven out of 12 of its known Victorian locations.

This native Australian rodent inhabits open heathland and coastal areas, mostly feeding on native plant seeds, leaves and fungi. It’s quite possible the New Holland Mouse has an important role in seed dispersal. You can tell it’s different from the house mouse by its larger ears and eyes and a distinct lack of ‘mousey’ odour. Once a continuous population across the east coast of Australia, it is now declining in numbers.

The major threats

The New Holland Mouse is increasingly under threat from loss of habitat as well as predators such as feral cats and foxes. Dieback caused by Cinnamon Fungus to its food source is a major issue. Bushfires and the competition from introduced rodents also put this native mouse at risk.

The plan for fighting extinction

Zoos Victoria is committed to improving the long-term future for the New Holland Mouse. We are researching population size and structure across the New Holland Mouse range and developing plans to reintroduce the New Holland Mouse back to its former range, where it belongs.
