Distribution and abundance of eastern barred bandicoot, their habitat use and response to restoration

The eastern barred bandicoot (Perameles gunnii) is extinct in the wild in mainland Australia, surviving only in reserves and islands where it is protected from introduced predators.  In Tasmania, the species was previously widespread over northern and eastern Tasmania despite the presence of the introduced predator, the feral cat.

In recent years, the population has been in decline but is still relatively common within the northern part of the Northern Midlands and West Tamar municipalities. It is thought that the key threats include loss of refuge and foraging habitat through a decrease in structural complexity in the understorey, as well as a higher incidence of predatory feral cats in the landscape.  Climate change with hotter and drier conditions expected is also likely to affect the conditions within the understorey, perhaps influencing the availability of particular invertebrates or the structure and complexity of the understorey.

The project will use wildlife cameras, trapping and movement tracking techniques to study eastern barred bandicoots in northern Tasmania to answer the following questions:

  1. What are the drivers of bandicoot abundance in Tasmania?
  2. What constitutes good habitat for bandicoots?
  3. Do bandicoots respond to restoration interventions?
