Thriving, surviving and recolonising: population dynamics of declining savanna mammals following fire

Project: Research

Project Details


The severe decline of small mammals across northern Australia’s tropical savannas is one of our nation's most urgent conservation challenges. An appropriate management response
is hampered by our limited mechanistic understanding of the drivers of mammal decline. However, there is increasing evidence that predation by feral cats plays a key role, especially when exacerbated by severe disturbance regimes, such as frequent, intense fires and heavy grazing by feral livestock. Given that cats are notoriously difficult and expensive to control over large areas, attention is turning to whether it is more feasible to moderate disturbance regimes to enhance the persistence of small mammals. This project will use the Tiwi Islands as a model system to explore the impacts of fire, cats and livestock on one ground-dwelling native mammal species: the northern brown bandicoot (Isoodon macrourus).
