Data describes vegetation extent priorities for each stream reach across the Melbourne Water region. Each reach is classified as either high, medium or low priority. To meet the performance objectives of the Healthy Waterways Strategy 2018 (HWS2018), high priority reaches need to be revegetated by 2028. To meet the target trajectory scores of the Healthy Waterways Strategy, medium priority reaches need to be revegetated by 2068. Vegetation priority reaches were determined by a combination of decision support tools and the co-design process. The decision support tool used was Zonation, which prioritised management actions across the region with the objective of improving instream habitat suitability for platypus, fish and macroinvertebrates.

Results are considered fit for purpose (i.e. for waterway planning). This data set covers the entire Melbourne Water region with the exception of very small areas close to Port Phillip Bay or Western Port. For example, there are small areas of French Island which are not captured.
This data set was created using: 1. Streams dataset for the Healthy Waterways Strategy 2018. This layer was developed by GraceGIS using Melbourne Water layers as inputs.
