The Grass Tree Trail in Woowookarung Regional Park was unveiled on Wednesday morning.

The path, which takes an estimated 2,400 steps to complete, is lined by many examples of the striking, slow-growing plant which is abundant in the area.

The trail has been designed to allow visitors to appreciate the trees, while protecting them from a destructive fungus.

The Courier's Nature Notes columnist Roger Thomas says the plants can live more than three centuries and are known for the speed of their response to fire, being among the first plants to show green once bushfires have passed through.

"We are fortunate to have many austral grass-trees in the Woowookarung Regional Park on the edge of Ballarat, where they will be preserved and treated with respect," Mr Thomas wrote in a previous column.

The plants are now under threat from a microscopic organism called cinnamon fungus, which can be spread by walkers and bike users.

Parks Victoria, the state-funded body that manages the park, say protecting flora from the risk has been an important part of working out where to install infrastructure.

As well as highlighting the grass trees, the trail weaves through historic water races, mine shafts and prospecting sites.

It is the latest in a series of developments at the 641-hectare piece of land, which officially became a regional park in 2016.

The Friends of Canadian Corridor successfully applied for financial backing using the Pick My Project scheme, attracting $78,005 of state government funding.

Local member for Buninyong Michaela Settle was joined by the minister for regional development Mary-Anne Thomas for the opening, as well as representatives of Parks Victoria and the Friends of Canadian Corridor.

The track, which measures a total 1.8-kilometres and takes an estimated 45 minutes to complete, is just one of a number of projects at the park. These include a Dementia Sensory trail, a new visitor node, car and bus parking and a picnic area.

The president of the Friends of Canadian Corridor Bob Hartmann thanked the government and Parks Victoria for their work.

"Woowookarung is going to be pivotal for health and wellbeing," he said. "This trail is really important for our community."

He also made a point of referring to the grass tree by its Wadawurrung name, bag:gup.

The entrance to the Grass Tree Trail is accessible near the lookout on Bakers Road (see map above).
