The Millbrook Reservoir Reserve revegetation project by SA Water has achieved a remarkable milestone by winning the Environmental Stewardship Award at the 2023 Parks and Leisure Australia (SA/NT) Awards of Excellence. This innovative initiative aims to restore a 24-hectare site into a thriving open grassy woodland habitat, showcasing 82 native plant species and over 2.2 million native grasses.
The restoration process involved a thoughtful combination of trees, large shrubs, and grasses, resulting in the re-emergence of woodland bird species like the Buff-rumped Thornbill and Dusky Woodswallow. Shaun Kennedy, SA Water’s Vegetation Services Specialist, highlighted the rarity of the grassy woodland system in the Mount Lofty Ranges of South Australia. Due to extensive land clearance over the years, only 13% of native vegetation remains in the region, making the restoration project critical for biodiversity conservation.
The innovative restoration techniques employed a holistic approach, combining ‘top-down’ and ‘bottom-up’ methods. This involved establishing tree and shrub habitat structure while sowing a diverse understorey component throughout the site. The planting designs were carefully tailored to the undulating landform, creating Box, Pink, Blue, and Red Gum Woodlands with transient wetlands to support a rich variety of species.
In addition, the project incorporated repurposed tree limbs from the Kangaroo Creek Reservoir upgrade, creating 70 log stacks strategically placed to provide habitat for birds and reptiles. This effort has attracted breeding pairs of the declining Dusky Woodswallow, along with the return of three other threatened species.
Beyond the award recognition, the Millbrook Revegetation Project’s true merit lies in its significant contribution to biodiversity conservation and the thriving ecology observed in the area. These revegetation initiatives play a crucial role in creating healthy catchments and ecosystems, safeguarding water quality, and preserving native flora and fauna for future generations.
Associate Professor Martin Breed from Flinders University commended the project, stating that it sets an exemplary standard for ecosystem restoration. By sharing the Millbrook Revegetation Project with peers and students, he hopes to inspire the next generation of restoration scientists, practitioners, and policymakers to be bold in their environmental endeavors.
The success of the Millbrook Revegetation Project highlights the potential for innovation and functional restoration in addressing today’s environmental challenges. This initiative not only restores the ecological balance but also serves as a beacon of hope amidst the broader environmental crises. By promoting such projects, we can inspire positive change and pave the way for a greener, more sustainable future.
