Red gums need at least 100 years to begin developing nesting hollows, but many older gum trees have been removed.
Tree hollows provide nests and homes for wildlife such as possums, gliders, birds, bats, snakes and lizards.
These animals now have 43 new homes in which to nest and shelter, thanks to a project to accelerate the formation of tree hollows in large red gums. The project was auspiced by Warringal Conservation Society and supported by one of our environment grants.
The hollows were made by arborists wielding power tools. Cameras have captured keen interest from rosellas, galahs, cockatoos, lorikeets, ducks, owlet nightjars, possums and Krefft’s gliders.
