Australia has the highest number of hollow-dependent species in the world! Possums, gliders and phascogales as well as lorikeets, parrots, kingfishers, owls and microbats all use hollows.1 This is no doubt due to the proliferation of Eucalypt species across the continent over many millennia. Many of these trees are long-lived and after a century or so they start to develop hollows and cavities. These naturally formed hollows provide places for these species to shelter, breed and feed.
Since European settlement, there has been a significant loss of the hollows through deforestation and degradation of habitats. This has had a significant impact on many endemic species that have evolved and depend on these hollows.2
While many landowners and managers as well as Bushcare groups are rehabilitating and where possible replanting Eucalypt bushland, it will take many decades before natural hollows become available for local wildlife. To address this problem, many people have...
The dedicated staff of the Moreton Bay Regional Council are passionate about our wildlife areas, and I was recently invited to attend a pre-planning session for an area of reserve adjacent at Hays Inlet. The planning process looks at a procedure of developing a fire management plan to prevent hot destructive fires and maintain biodiversity using methods such as mosaic burning.

The first impression to the observer is the actual size and range of the area. It reminded us that there is still a large region of potential conservation land adjacent to the wetlands of Hays Inlet and the Peninsula. An intense bushfire passed through the area in 2014 and you could still see signs of the damage on several trees. However, there was also signs of recovery with a number of new trees germinating after the fire and in the process of reaching the mid canopy.
You can still see evidence from the 2014 bushfire
