We can hardly believe it, but it’s been three years since we installed more than 100 artificially created hollows in the Wombat State and Cobaw State Forests, in areas impacted by the 2021 storms.
We’ve been regularly monitoring the hollows since installation and are excited to report that we have even more use by target species the Southern Greater Glider (Petauroides volans) and other native species.
During our last monitoring trip, we discovered that all of the Greater Glider designed hollows in one area of the Wombat State Forest had been used by gliders, and there was evidence of heavy use in the form of worn bark around the entrances on most host trees (glider ‘landing pads’). We also recorded Kreftt’s Gliders, Common Brush-tailed and Ring-tailed Possums, Crimson Rosella’s and White-throated Treecreepers utilising the hollows.
More than 30% of the hollows showed signs of use, with either animals or nests inside. Our team also installed a further 100 hollows in 2024, and we recently monitored those for the first time. Amazingly, after only a few months, 21% of these new hollows also showed signs of use or had an animal present.
We will keep monitoring our hollows and incorporating any learnings and observations into improving the design and installation process in the future.
