Healthy Waterways VisionsVegetation Quality Visions – User NotesThe Healthy Waterways Visions communicate Melbourne Water’s longer term aims for the form and function of waterways in the Port Phillip and Westernport region.Overview of the Vegetation Quality VisionsRiparian and aquatic vegetation are important components of a healthy, functioning waterway. Vegetation provides a number of functions important to river health including:• bank stabilisation and erosion control• improvement to water quality through buffering and natural filtering• shade and regulation of water temperature• shelter and provision of habitat connectivity for wildlife and pathways of gene-flow through the landscape• provision of organic matter fundamental in the food chain of waterway ecosystems.Riparian and aquatic vegetation are an important component of any vision for waterway form and function. The vegetation quality vision is designed to indicate the riparian vegetation quality that can be achieved and maintained along Melbourne Water’s waterways.Development of the Vegetation Quality VisionsThe 2009 and potential (2030) vegetation quality levels were assessed via a series of workshops with representatives from River Health, Capital, Maintenance and Minor Capital, Stream Frontage assessors and independent experts.The waterways are rated from 1 (very low) to 5 (very high) for both current (2009) and potential (2030) vegetation quality using the following ratings:1. Very Low Riparian vegetation is highly modified, predominantly comprising exotic species.2. Low Riparian vegetation is highly modified, fragmented and meets social and amenity requirements3. Medium Riparian zone consists of fragmented relevant EVC vegetation.4. High Riparian vegetation is relatively intact with structural elements present with high connectivity.5. Very High Riparian vegetation is intact with all structural components present and very high connectivityFor each vegetation quality level, the following characteristics are described: Vegetation structure Species composition Instream vegetation Vegetation continuity and connectivity Weediness Regeneration Typical land use setting Suitable weed and vegetation management techniques to achieve the vision
