Restoring waterways near Avon River and Nuntin Creek starts the landholders partnering with West Gippsland Catchment Management Authority

WGCMA collaborated with landholders to restore two waterways in West Gippsland, benefiting the environment and bolstering resilience against climate change.

West Gippsland Catchment Management Authority (WGCMA) has been working with landholders on two projects to repair local waterways to provide a legacy for the environment and build a landscape more able to withstand climate change impacts. The projects on two farms - one a dairy enterprise and the other with beef cattle - are separated by a few kilometres and situated along the Avon River and Nuntin Creek.

Since European settlement, these waterways have provided water for stock and irrigation and borne the impact of agricultural practices as rivers were straightened rivers, dams constructed, and wetlands drained.

CEO (Chief Executive Officer) of WGCMA, Martin Fuller said, "Partnering with landholders like the Connor and Cliff families is such a wonderful part of our work, It's partnerships like this that help put another small piece in the jigsaw of repairing and improving landscapes right across the West Gippsland CMA region."

The 11-hectare Connor site has around 300 metres of Avon River frontage which would be inundated in even a minor flood event. Before this project, a historic drainage channel quickly returned this floodwater to the Avon which significantly reduced the time the water remained on the property and contributed to an increase in salinity.

Wetland restoration completed

Earthworks to restore the natural flow of water on the site were conducted in mid-November 2022. The wetland will now retain floodwater for longer, provide important habitat for wetland flora and fauna and slow the flow of nutrient heavy flood waters towards the Gippsland Lakes.

It's clear when walking the Connor property, the affection both Mary and Howard Connor have for the site, which they purchased three years ago. "I love the landscape. I love plants and it's a challenge - but not a bad one!" said Mary.

Livestock have been excluded from the site for three years, allowing natural regrowth to occur. "At the moment you can see there are lots of red gums coming along in various stages of growth, some really just erupting seedlings and others two to three metres high since we stopped the cattle coming in," said Howard.

Wetland revegetated naturally

Revegetation funded by this project and planted by Gunaikurnai Land and Waters Aboriginal Corporation (GLaWAC) will add to this natural regrowth, supplying greater resilience and increasing genetic and species diversity. Seed from nearby salt affected areas was used for the planting and will increase the hardiness of the wetland in the face of encroaching salinisation.

Less than five kilometres away is the Cliff family farm, milking 650 cows on land bordered by the Avon River, Princes Highway and the Nuntin Creek. The seven-hectare revegetation site includes naturally occurring wetlands, which for generations have been incorporated into the day-to-day farming practice.

Today the farm is the picture of a modern farming enterprise. Large centre pivot irrigation, cows wearing data collecting collars, a 40-stand rotary platform and, unfortunately, a near complete absence of native trees. "We bought this property in 1948. My dad has recollections of much more native flora and fauna such as paperbarks and ringtail possums. Now, there are a couple of big gum trees, that's about it," said Anthony Cliff.

Rejuvenating local environment

Given the rather denuded landscape and the Nuntin Creek historically being seen largely as a drain for the neighbouring farms from the Macalister Irrigation District, the project Anthony has embarked on feels like a fresh start for this small pocket of the local environment. An area totaling more than six hectares has seen willow removal, weed treatment, fencing, and the planting of 5,000 native trees and shrubs.

"They've planted a few different species around the site, trying to build some resilience around climate change. It's a bit of an experiment but it will look fantastic in a few years' time," says Anthony, who sees the emergence of climate change as a prompt to continue some of the practices he has used on the farm for many years as well as to build in some new ones.

Planting for carbon

Anthony, who is working on fencing off and planting around other water courses on the farm, says that small individual projects shouldn't be dismissed, but rather seen through the lens of multiple projects all combining to make significant differences to local environments.

"If everyone gets on board, they'll contribute and add up to one big project - suck the carbon back in by planting trees. We've got to do a lot more here, but if you can get the whole district engaged and everyone doing a little more, that makes a difference," says Anthony.
