What are waterways? Throughout this Strategy the term waterway refers collectively to rivers and creeks, wetlands and estuaries

There is a real need to take action to avoid square kilometres. About 10 per cent of the catchment retains an otherwise inevitable decline in waterway health. its natural vegetation, 80 per cent is used for agriculture and 10 per cent is used for urban development – confined to greater Opportunities Melbourne and larger townships.

Maribyrnong - Healthy Waterways Strategy 03 Maribyrnong: Collaboration process Co-designing our future

One of Melbourne Water’s responsibilities is to create long-term April 2017 - Maribyrnong catchment plans that ensure the Maribyrnong catchment’s waterways are collaboration commenced healthy, liveable and accessible for future generations.

Collaborative process December 2017 In April 2017, the Maribyrnong Catchment Collaboration Vision, goals and waterways values defined commenced the process to identify and develop the refreshed Healthy Waterways Strategy for the Maribyrnong catchment. The collaboration was made up of interested community members, organisations and agencies to: March 2018 Preliminary Targets released • Develop a vision and goals for their catchment • Explore issues, opportunities and aspirations within the catchment • Identify where stakeholders need to focus their efforts and energy. March 2018 In developing this draft Strategy, six workshops were held with Engagement on Preliminary Targets over 80 participants representing around 50 organisations attending at least one workshop (the back pages list organisations that participated in this process). June 2018 Most recently the collaboration considered preliminary targets Draft Strategy released for the catchment and feedback from this process was used to develop this draft Strategy.

Maribyrnong - Healthy Waterways Strategy 05 The program logic

Figure 3 Program logic for developing the Strategy

06 VISION

A Maribyrnong catchment whose ecological health has significantly improved since 2018. It is accessible, used and valued by the community. Its collaborative management reflects the contributions of Traditional Owners and the broader community.

GOALS

1. Environmental: Management is helping create a preferred future for the Maribyrnong’s environments by assisting species and habitats to change, adapt, move or be replaced as the catchment and climate change. The Maribyrnong River and its tributaries are important bio-links – corridors of secure, high quality habitats that allow plants and animals to move and adapt to changes in catchment conditions and climate. Water quality and flows provide for healthy and diverse populations of plants and animals. Stormwater is managed to enhance rather than destroy waterway health. 2. Social: Waterways across the Maribyrnong are places that provide continuous, connected and accessible open spaces for public enjoyment and recreation. 3. Education: Public authorities, community groups and hundreds of individuals across the catchment share their knowledge of the Maribyrnong and take regular action to help pursue this Strategy’s goals. Education programs are resourced and coordinated across many organisations that are working or involved within the catchment. 4. Decision-making and action: Long-term monitoring supports adaptive management by tracking progress towards this Strategy’s goals. Urban planning decisions make explicit reference to their potential impacts on waterway environments. The Planning and Environment Act includes overlays to protect the river, its tributaries, floodplains and escarpments. Effects of planning decisions are monitored to support evaluation and learning. Melbourne Water is seen by all parties to the Strategy as a successful facilitator, enabler, coordinator and leader.
