Healing the River, One Bank at a Time: Riverdell’s Regeneration at Hillier along the Gawler River
On a quiet bend of the Gawler River at Hillier, a degraded riverbank is being carefully brought back to life – through thoughtful planning, skilled on‑ground work and a strong commitment to community stewardship.
With support from the Northern and Yorke Landscape Board's Grassroots Grants Program, The Emissaries (SA) Inc. is delivering the Riverdell Riverbank Regeneration 2025 project: a targeted effort to stabilise eroding banks, control invasive weeds and rebuild native riparian habitat along the northern bank of the river.

Tackling erosion at its source
Years of pressure from flooding, vegetation loss and invasive weeds have left this stretch of riverbank unstable and vulnerable to further degradation.
The project focuses on:
- Stabilising eroding riverbanks to prevent sediment loss
- Reducing invasive plant cover that competes with native species
- Re‑establishing diverse native vegetation suited to flood‑prone conditions
By addressing these issues together, the project improves both the immediate site and the broader health of the Gawler River corridor.

A staged, best practice approach
Riverdell’s regeneration follows a carefully staged plan, delivered by experienced, ChemCert‑qualified contractors.
Early stages concentrate on removing priority weeds – including boxthorn, olives, ash, pepper trees and castor oil plants – using a combination of mechanical removal and targeted herbicide application.
Once weed pressure is reduced, the focus shifts to revegetation, planting locally appropriate species that:
- Anchor soil and reduce erosion
- Suppress future weed growth
- Improve habitat for birds, insects and aquatic species
Planting is timed to take advantage of winter rainfall, improving survival rates and long‑term success.

Putting the right plants back in the sand
More than 300 native tube‑stock plants will be planted in degraded areas, helping stabilise dunes and provide habitat for coastal birds.
By removing invasive weeds and replacing them with locally appropriate native species, the project restores the structure and function of the dune system – allowing it to respond more effectively to wind, storms and changing climate conditions.

Working together along the river
A standout feature of this project is its collaborative mindset.
The Emissaries are working in alignment with:
- Gawler River Riparian Restoration (GRRR)
- The Food Forest
- Local landholders on the opposite riverbank
- Specialist revegetation contractors
This coordination ensures efforts along the Gawler River are connected rather than piecemeal – building momentum across the catchment.
Benefits for nature and people
The ecological benefits are clear:
- Improved riverbank stability
- Better water quality through reduced sediment runoff
- Enhanced habitat and ecological connectivity
- Increased resilience to flood and climate extremes
But the project also delivers strong social outcomes.
Through volunteer planting days, educational signage and community involvement, Riverdell is creating opportunities for people to connect with the river – not just as landholders, but as caretakers of a shared landscape.

Measuring success for the long term
Measuring success for the long term.
Success won’t be judged by planting numbers alone.
The project tracks:
✅ Reduction in erosion and bank slumping
✅ Survival and growth of native plantings
✅ Decreases in invasive weed cover
✅ Community participation and engagement
By combining monitoring with ongoing maintenance, the project is designed to last well beyond the grant period.
Impressive leveraged outcomes, looking after what makes the place special
With $10,000 in Grassroots Grants funding, leveraged by nearly $20,000 in in‑kind contributions, this project shows what’s possible when community commitment is matched with professional expertise.
Riverdell Riverbank Regeneration 2025 is a reminder that meaningful restoration doesn’t have to be large‑scale to be impactful – it just needs to be well planned, well delivered and deeply connected to place.

Grassroots Grants are delivered by the Northern and Yorke Landscape Board and are a great example of South Australia’s landscape levy at work, supporting local knowledge and community‑led action empowering communities to care for their environment.
💚 Over $3 million has been invested in in the health and liveability of our region through the Grassroots Grants program since it started in 2020.
💚 The Northern and Yorke Landscape Board has provided over $1.4 million to 186 community-led projects across the region. This is ~matched in kind by the grant recipients.
💚 Grants of $2,000 to $10,000 are available for one-year projects.
💚 It is an annual program, with applications opening in early April and successful applicants announced in July.
💚 This year's program (2026-2027) has awarded $181,841 has been awarded through the landscape levy to support volunteers, schools, community groups, First Nations, councils and landholder groups sustainably manage landscapes through on-ground work and education. View recipient list here
