Greendale Stage 2 Extension Project wrap-up: Strong community action

The Greendale Stage 2 Extension Project, led by the Victorian Serrated Tussock Working Party (VSTWP), has concluded with encouraging results across the Moorabool Creek Catchment. Running from April 2024 to February 2025, the project targeted serrated tussock infestations across 2,600 hectares of primarily agricultural and hobby farming land, with a focus on both protecting valuable pasture and safeguarding key ecological areas.

Project Overview

Serrated tussock (Nassella trichotoma) is a highly invasive, drought-resistant perennial grass that threatens both productivity and biodiversity. Known for spreading rapidly in degraded pastures, it was found scattered throughout the target area—with higher densities in the southern and western sectors.

The area is rich in native grass species such as Common Tussock-grass (Poa labillardierei), Wallaby Grass, and Spear Grass, alongside significant waterways including the headwaters of the Werribee River. These assets make the Greendale region a high-value landscape requiring proactive weed management.

Landholder Engagement

Under the guidance of Extension Officer Ivan Carter, the project team successfully contacted 128 land managers, assessed 115 properties, and inspected 2,070 hectares of private land plus 12 hectares of roadside. Serrated tussock was identified on 17 hectares, with 12 hectares already treated thanks to landholder cooperation—some even removing plants manually during inspections.

Each participating landholder received:

• A tailored information package on serrated tussock ID and control,
• On-site property inspections and mapping of infestations,
• Technical advice suited to local conditions,
• And, where needed, Rapid Appraisal Management Plans to guide follow-up.

While only a few landholders initially responded to the launch, in-person follow-ups proved far more effective. This door-to-door approach allowed for direct engagement, with Carter noting it was a key factor in the project’s success.

Challenges and Compliance

Despite the positive engagement overall, two properties remain untreated due to persistent or uncontactable landowners. One owner had previously received a compliance letter from Agriculture Victoria, while another did not respond despite multiple outreach efforts. These properties have now been flagged for potential regulatory enforcement.

Collaboration and Communication

The success of the project is also credited to the Moorabool Landcare Network, Moorabool Shire, and Southern Rural Water, who supported communication efforts and roadside treatments. Media releases and case studies helped raise awareness through the local landcare groups.

Looking Forward

The Greendale Stage 2 Project reinforces the importance of local action and community support in weed management. While areas like Ballan North remain close to Victoria’s core infestation zone, projects like this one demonstrate that effective containment and reduction are achievable through coordinated effort.

The VSTWP continues to advocate for education-first approaches, supported by strong partnerships and persistent follow-up. Greendale is now better positioned to keep serrated tussock in check—but sustained effort will be critical to long-term success.
