Did you know that about 15% of Australian fauna need tree hollows for shelter or to raise their young?
Here at Sydney Olympic Park, we have many hollow-dependent creatures like possums, microbats, parrots, cockatoo, rosellas and owls.
As hollows take a long time to form (over 100 years) and are scarce in our urban environment, we provide nest boxes to help maintain local fauna populations.
This month, we hosted a one-day regional forum called Hollows for Habitat in partnership with Greater Sydney Local Land Services. The forum focused on nest boxes and hollow creation, to explore what makes these supplementary habitats successful with our hollow-dependent animals.
The event brought together 200 experts and enthusiasts from a broad background – including federal, state and local governments, educational institutions, consultants and contractors, environmental groups and NGOs, community and producer/industry groups as well as private landholders.
A wide range of topics were covered in presentations:
- How to make long-lasting nest boxes
- Pruning of live and dead standing trees to create hollows for multiple species
- Large-scale research into microbat use of nest boxes
- Airlifting logs into a reserve for the native bush rat
- Monitoring the use of nest boxes by Pygmy Possums
- Sydney Olympic Park Authority’s nest and roost box project, which has been successful for 3 microbat species, the Red-rumped Parrot, and the Common Brushtail Possum
Sydney Olympic Park Authority ran two guided tours into the corridor between Newington Nature Reserve forest and wetland to showcase our nest and roost boxes. At the same time, Victorian arborists Ben and Pat Kenyon demonstrated how to use a chainsaw to create bat roosts and bird hollows in trees.
Knowledge shared is knowledge gained. The forum has created a wider and stronger network of practitioners in habitat augmentation, which will benefit our native hollow-dependent animals.
