Past and Present Distribution of the Eastern Barred Bandicoot (Perameles gunnii) in the Midlands, Tasmania

Abstract

The Eastern Barred Bandicoot, Perameles gunnii, is still relatively widespread and abundant in Tasmania, in contrast to the situation on mainland Australia where the species has declined to a single wild population. However, despite its relative security in Tasmania, there is evidence that a significant shift in the species' distribution has occurred since European settlement. The original range of P. gunnii in Tasmania can be postulated from the pre-European distribution of its original habitat (native grasslands and grassy woodlands), which occurred almost exclusively through the Midlands region of the state. We present anecdotal data collected from residents throughout the Midlands and adjoining regions which indicate that P. gunnii is now absent from the majority of its original range. The removal of >80% of the original Midlands native vegetation through clearing for agriculture and stock-grazing is suggested as the principal cause of this decline.
