Greening the Maribyrnong

Greening the Maribyrnong is a major environmental program revitalising degraded escarpments of the Maribyrnong Valley through the control of pest plants and animals and revegetation with indigenous shrubs and trees.

Its long-term ambition is to establish a naturelink stretching from the Macedon Ranges to inner Melbourne.

Its work focuses on rehabilitating large connecting sections of the Maribyrnong River escarpment, with work undertaken to date on the Maribyrnong River and its tributaries, Deep Creek, Jacksons Creek and Emu Creek.

Partners

Greening the Maribyrnong is a collaborative program supported by a range of government agencies, corporations, community groups and private landholders. The PPWCMA coordinates Greening the Maribyrnong on behalf of its partners, managing projects and leading the delivery of on-ground works, monitoring and reporting.

About the Maribyrnong catchment

The Maribyrnong River is the second biggest river (after the Yarra River) in the Melbourne metropolitan area and runs for 160 kilometres from its source on the Great Dividing Range. It flows through an urban environment in the north western suburbs of Melbourne before connecting with the Yarra River about 3.5km upstream of the Yarra River entrance to Port Phillip Bay. The tidal influence extends about 16 kilometres upstream to what was originally a natural rock ford at Avondale Heights. This separates the upper freshwater parts of the river from the estuary.

The river and creeks in the catchment tend to be deeply incised, exhibit a highly variable flow and are subject to extended periods of low flow. They are also characterised by poor water quality and loss of riverbank and aquatic habitat. The incised valleys through which they flow have valuable areas of remnant vegetation, including the highly valued river red gum.

The local community recognise the environmental values of the waterways, including the remaining native vegetation, platypus and growling grass frogs. The lower section of the Maribyrnong catchment is particularly valued for recreational opportunities including boating, kayaking, fishing, rowing and bike riding. Unfortunately, the waterway and the bay into which it flows remains threatened by several key pollutants and challenges such as urban growth and climate change.

Since settlement, the Maribyrnong valley has been subject to land clearing, overgrazing and the introduction of pest plants and animals. This has led to an overwhelming deterioration of the natural habitat available to support native birds and animals and created conditions that do support the natural regeneration of indigenous species. Its remaining native vegetation will not be replaced without human intervention driven by decisions and a vision for a different landscape. This is the vision of the Greening the Maribyrnong Project.
