Abstract

In Tasmania, a considerable proportion of the forested landscape is available for land clearance and production forestry, which has and will continue to result in a decline in hollow availability unless managed appropriately. All hollow-using species are listed as having priority status under the Tasmanian Regional Forest Agreement. To ensure the habitat for hollow-using fauna is managed effectively, we first have to understand the requirements of the species involved. This paper is a review of the distribution, hollow requirements and conservation status of the five species of arboreal marsupials, eight species of bats and 29 bird species that use hollows in Tasmania. The number of species that use hollows is lower than in many other areas of Australia, but these species represent a large proportion of the vertebrate fauna of Tasmania. Three of these species and nine subspecies are endemic to Tasmania and seven are exotic. Four bird species are listed as Threatened at the state and/or national level. Twenty-five of Tasmania’s hollow-using species are capable of using small hollows, 14 can use medium-sized hollows and three bird species are limited to using large hollows. Current records indicate that the highest diversity of hollow-using species is associated with dry forest areas.
