Topic: The value of forest remnants to Microchiropteron bats

University of Tasmania

Bats are an important forest-dwelling species, and likely to play a key ecological role in forest ecosystems as pollinators and regulators of invertebrate populations. The retention of forest remnants may be important in maintaining bat species, as forest remnants provide crucial foraging and roosting habitat.

This project will use passive bat call surveys to compare the use of forest remnants ranging from individual trees, clumps and larger patches with different levels of forest productivity, surrounding forest age and the amount of surrounding mature forest canopy in the landscape.

Unlike previous studies, this project will explore how the availability of forest habitat, including foraging and roosting resources, at the landscape level, influences bats in terms of habitat use and species assemblages. Results of this study will greatly contribute to understanding the habitat requirements of bats in Tasmania, and how effective our current forest management strategies are for maintaining Australia’s bat biodiversity.

This work follows on from Lisa’s honours work, and her work at the Forest Practices Authority where she investigated the use of retained forest by the Tasmanian common brushtail possum in logged forest in south-east Tasmania. An article featuring Lisa's work with the Forest Practices Authority features in BioBuzz 6.

As Lisa grew up in Tasmania she became really interested in fauna management during her Bachelor of Science degree at the University of Tasmania, where she majored in Zoology and Geography and Environmental studies.

Her supervisors are  Dr Sarah Munks and Dr Hamish McCallum of the University of Tasmania.

Her project is supported by the Forest Practices Authority, the CRC for Forestry, Forestry Tasmania and the University of Tasmania.

This project was part of the CRC for Forestry Biodiversity Project (4.2) (subproject 4.2.5) on management of forest species of high conservation significance, including threatened species.
