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.

About the Speaker

Ana Gracanin’s research focuses on the conservation and ecology of arboreal mammals in fragmented landscapes. She is particularly interested in understanding the population genetics, movement patterns, and habitat connectivity of these species. Her work explores the impact of environmental disturbances, such as wildfires, on endangered species such as the greater glider and the spotted-tailed quoll. She also studies tree hollows and their ecological role for hollow-dependent species, with a particular focus on the greater glider.
