In this presentation Ana Gracanin will discuss research investigating the effectiveness of carved hollows for greater gliders. All welcome
Abstract: The loss of hollow-bearing trees is a major driver of decline for hollow-dependent fauna, yet the effectiveness of artificial hollows remains uncertain. We conducted a pilot study in Monga National Park, carving 40 artificial hollows and monitoring their use for two years with remote cameras. While some hollows were occupied by a few different species, use by the endangered southern greater glider (Petauroides volans) was variable and relatively low. Our results identified some limitations in hollow structure and placement, alongside logistical and practical challenges in implementation. These findings demonstrate that carved hollows have potential as a supplementary conservation tool but require much more substantial refinement and long-term validation.
Bio: Dr. Ana Gracanin is a conservation biologist and Research Fellow at the Fenner School of Environment and Society, Australian National University, specialising in the ecology and conservation of arboreal mammals. Her research focuses on the endangered Southern Greater Glider and other hollow-dependent species, with particular interests in conservation genetics, and the impacts of wildfire, habitat fragmentation and habitat loss on arboreal wildlife. Ana leads and contributes to a range of habitat restoration projects trialling nest boxes and artificially carved tree hollows as solutions to the critical shortage of natural hollows in Australian forests, working closely with government and industry partners on applied conservation outcomes. An experienced tree climber, she conducts much of her fieldwork in the canopy itself, and is also a passionate wildlife filmmaker, documenting the nocturnal lives of the cryptic species she studies.
We meet in the Slatyer Seminar Room, on the first floor of the R N Robertson Building, 46 Sullivans Creek Road at the ANU. Head up the stepped ramp on the right as you enter the building. The Slatyer room will be on your left at the front of the building. Light refreshments will be served from 7pm with the talk to start at 7.30pm. Please bring a keep cup or mug for coffee or tea.
