Habit Recovery

Substantial vegetation recovery has been observed, with dense regrowth of shrubs and pioneering species such as Acacia and Goodenia ovata. This resurgence of diverse understory vegetation supports an increase in wildlife abundance and diversity by providing essential food, nesting, and shelter resources. However, some challenges remain. Thirteen bird species recorded in 2020, including the Bassian Thrush and Rainbow Bee-eaters, were not detected in 2024. Their absence may indicate habitat suitability issues or natural migratory fluctuations, necessitating continued monitoring and adaptive habitat management.

To support koala populations, ongoing planting of koala-preferred tree species—such as grey gum (Eucalyptus punctata), Sydney blue gum (Eucalyptus saligna), and cabbage gum (Eucalyptus amplifolia), which are included in the list of species being planted by the community.  Recent surveys detected minimal koala presence, yet the availability of suitable habitat suggests potential for recolonisation. Enhancing koala habitats through weed management and improved access to feed trees will strengthen the valley’s viability as a koala refuge.

Community-led restoration efforts are also crucial for vulnerable bird species such as the Gang-gang and Glossy Black Cockatoos. Establishing a diverse planting regime, including Allocasuarina and Casuarina species, will provide critical food resources, while additional flowering trees will support nectivorous and granivorous birds. Integrating native understory vegetation further enhances habitat complexity, benefitting various bird species.

Nest site availability remains a key conservation focus. Preserving mature hollow-bearing trees and installing artificial hollows can address breeding habitat shortages for hollow-dependent species. Additionally, fire and weed management practices are essential for maintaining habitat quality and controlling invasive species. Community-driven efforts, including low-intensity cool burns and dedicated weeding campaigns, can encourage natural regeneration and sustain diverse bird populations.

While comparative studies on taxa besides birds remain limited, it is likely that other species, such as ground-dwelling mammals, arboreal mammals, bats, and amphibians, are benefiting from these restoration efforts. Follow-up studies would provide valuable insights into their recovery and inform targeted management strategies. Expanding artificial hollows would further support arboreal mammals, while riparian restoration and weed control efforts would benefit amphibians.

Predator control remains a priority, particularly targeting cats and foxes. Conducting follow-up studies on predator abundance will inform a data-driven approach for managing feral predator populations. Ongoing monitoring and adaptive conservation strategies will be essential for ensuring the valley’s long-term ecological health and resilience.
