The Great Western Wildlife Corridor (GWWC) is an important landscape connection for the glossy black-cockatoo (Calyptorhynchus lathami lathami). Located between Bullio and Bungonia, it’s the only vegetated habitat corridor between the Southern Blue Mountains and Morton National Park.
Glossy black-cockatoos, or glossies, are listed as vulnerable in News South Wales. These amazing birds need corridors of native vegetation with big tree hollows for nesting and feed trees such as she-oaks (Allocasuarina spp.) to move across the broader landscape and thrive.
The GWWC is being increasingly divided into smaller lots and cleared for new housing, fences and infrastructure. This fragmentation of the corridor along with heavy impacts by the black summer bushfires means that without help we may lose a vital landscape connection for Glossies into the future.
The Glossies in the Mist project
The project aims to:
- secure foraging and breeding habitat for glossies by increasing the health of the GWWC on private land
- identify and protect key feed trees
- map and protect nesting hollows within the GWWC
- engage the community and landholders to care for glossies and their habitat.
Funded by the Saving our Species program and the Wingecarribee Shire Council’s Environment Levy, the project partners with landholders in Bullio, Wombeyan Caves, High Range, Mandemar, Canyonleigh, Belanglo, Paddys River, Wingello, Penrose, Tallong, Marulan and Bungonia areas within the GWWC.
Results
From 2018 to 2023:
- 25,000 trees planted across the corridor to improve connectivity and habitat for Glossies
- 44 hectares (ha) planted across 31 properties, totalling 200 ha contributed to Wingecarribee Shire Council’s Land for Wildlife program
- 15 nest boxes deployed and monitored
- 15,000 nest-box monitoring photos processed by 545 citizen scientists in the Australian Museum’s Digivol platform, finding one female glossy checked out a nest box in 2021
- 850 sightings of glossies and 2,300 records of feed trees submitted to BioNet
- over 280 individual females identified from photos through the Flossy ID citizen science project.
