WHAT PROGRAM OF WORKS MAKES UP THE BARWON FLAGSHIP
During 2022 - 2024 the initial focus of the Barwon Flagship Project is the Upper Barwon and is about working together with landholders, key agencies, and community groups to develop and trial strategies that can be applied to priority Willow (Salix spp) and Reed sweet Grass (Glyceria maxima) chokes using riparian management practices. This will improve the delivery of environmental water within the Upper Barwon and further down the Barwon River.
Riparian land is the ‘buffer zone’ between water and land. The land could be used for anything from a recreation reserve to an area for livestock to graze.
It's important to keep riparian land healthy and well covered with vegetation to help maintain a healthy waterway. This is of particular relevance to the Barwon River as the catchment is highly modified which adversely impacts the quality and flow of water in the river.
Healthy riparian areas have many benefits to landholders including improved water quality for stock, increased land value, and contribute to nature conservation.

WATERWAY PROTECTION PROGRAM
Currently the Corangamite CMA Waterway Protection Program is finalising applications for funding for a recent Expression of Interest (EOI) process. Incentives are available through this program for fencing, weed control, revegetation, stock crossings and off-stream water points, willow removal and pest animal management. The successful applicants will be announced at the end of the month.
FLAGSHIP RIPARIAN PROGRAM
Flagship riparian works are a new program and will focus on trialling site specific, innovative approaches, developed in collaboration with land managers. Opportunities for demonstration sites are being investigated and these will be further explored at the open house sessions scheduled for June (more detail in ‘Events’ section, below).
RECOGNISING GLYCERIA MAXIMA
Glyceria maxima or Reed Sweet Grass is a highly invasive grass species which creates a dense floating monoculture, reducing biodiversity, dam capacity and increases flood risk.

Glyceria thrives in temperate climates with full sun, access to high levels of nutrients, in slow moving water columns at a depth of 0.5 to 1.5 meters. The best control methods are to suppress its growth long-term – this is achieved by shading and increased summer flows in rivers; and maintain the natural vegetation – Glyceria doesn’t grow underneath dense stands of vegetation, even small buffers of vegetation will reduce the density of Glyceria and therefore its impact on the system.
Small infestations should be treated ASAP. If you think you may have Glyceria on your property, please contact Angus Donaldson on email@example.com or 0409 794 234.
