Vision: tba
Goals • The environmental values and significant ecological processes of all of the Yarra Catchment waterways are protected and improved. • Riparian and instream habitats provide landscape connectivity, allowing the movement of native species and promoting resilient native flora and fauna populations. • Cultural and heritage values are recognised, protected, maintained and enhanced. • Communities and individuals connect with and appreciate the values of waterways. Waterway corridors are used appropriately for places of solitude, enjoyment of nature, and active and passive recreation that support mental and physical well‐being. • An engaged and knowledgeable community in the Yarra catchment acts to protect and promote sustained waterway values. Our waterways are a place of continuous learning. • The waterways of the Yarra Catchment support natural system maintenance, potable and agricultural water supply, commerce and tourism in a balanced and environmentally sustainable manner. Performance objectives (achieve in 1‐10 years) • The Yarra waterways are managed in a transparent and collaborative governance framework that allows for strategic, • Reduce impacts of stormwater on waterways; focus on urban growth and rural townships innovative and integrated ways to protect waterways across public and private land. • Improve condition and extent of riparian vegetation in rural and urban areas by protecting high • The cultural, historical, amenity values and landscape settings of all modified waterways are protected and improved. quality vegetation, managing threats and building resilience • Improve environmental flows and protect drought refuges in the context of climate change Waterway Values (10‐50 year targets) • Provide connectivity for fish along major waterways through removal of barriers • Reduce nutrient and sediment runoff from rural land and areas of urban development; ensure • Birds are currently low, trending to low; with a potential chance of moderate no net increase in nutrient and sediment loads to protect the health of Port Phillip Bay • Protect and improve high quality wetlands within the catchment and fill knowledge gaps for • Fish are currently low, trending to moderate; with a potential chance of moderate remaining wetlands to inform future management actions • Protect and improve signficant environmental and social values of Yarra River estuary, including • Frogs are currently low, trending to very low; with a potential chance of low managing impacts of climate change • Traditional Owners are supported to recognise, protect and promote intangible and tangible • Macroinvertebrates are currently moderate, trending to moderate; with a potential chance of moderate cultural values and to have a role in protecting and improving waterways • Provide systems to share knowledge and information between communities and stakeholders; • Platypus are currently low, trending to very low; with a potential chance of moderate to empower communities to participate and influence waterways management • Protect vegetation, amenity and other social values along the Yarra River and tributaries • Vegetation is currently moderate, trending to very low; with a potential chance of moderate • Improve understanding of existing rules around land management practices and increase resourcing for enforcement, capacity building and behaviour change • Address significant risks to values from pollution (water quality) from emerging contaminants of • Amenity is currently high, trending to high; with a potential chance of very high concern such as microplastics, pesticides and pharmaceuticals PRELIMINARY Waterway Targets • Connection is currently high, trending to moderate; with a potential chance of high

Two wetlands are located within Westgate Park. Quarrying for sand resulted in the two wetlands in the park – the larger fresh water lake having a large and diverse bird population but the smaller lake is highly saline, polluted with heavy metals and organics and often coloured pink by algae. Significant environmental projects have increased the environmental and social values of the wetlands.

The Yarra River estuary extends abut 22 km from Dights Falls to Newport, north of Hobsons Bay. It has high ecological, social, aethetic and recreational values as it flows through the city and eastern suburbs of Melbourne to Port Phillip Bay. It is a 'salt‐wedge' estuary, where the mixing of salt and freshwater is influenced by freshwater inflows over Dights Falls.
