Riparian and Stream Bed Vegetation Metrics for Melbourne Water Subcatchments

Vegetation coverage statistics for riparian zones and stream beds across the Melbourne Water region, developed for the Healthy Waterways Strategy 2018. It was created by GraceGIS using 2016 vegetation data and includes derived statistics at the subcatchment level for reporting and target setting.

Use Cases

• Analyze vegetation coverage within the 20-meter riparian zone outside the Urban Growth Boundary to assess habitat health.
• Compare vegetation metrics between the 10-meter riparian zone within the Urban Growth Boundary and the streambed layer to study urban impacts.
• Use subcatchment-level statistics derived from the HWS Vegetation Streambed Riparian (2016) layer for environmental performance reporting.
• Map vegetation coverage targets for waterways using the assembled riparian and stream bed polygons.

Strengths

• Based on 2016 vegetation data, providing a specific temporal snapshot.
• Includes separate metrics for riparian zones and stream beds, allowing for comparative analysis.
• Covers the entire Melbourne Water region, offering a complete spatial scope for the area.

Limitations

• The underlying vegetation data is from 2016 and may not reflect current conditions.
• Specific row counts, column details, and sample data are unavailable for assessing dataset scale and structure.
• Accuracy and completeness are not guaranteed by the data provider, requiring user validation.

Provenance

Source

Melbourne Water Corporation, via the Melbourne Water Open Data Hub.

Collection Method

Developed by GraceGIS using the MW Drainage Network, ISC 2010 streambed data with buffers, and the HWS Vegetation Streambed Riparian (2016) layer to create polygons and derive subcatchment statistics.

Time Range

Vegetation metrics are from 2016.

Freshness

The dataset record was last updated in March 2026, but the core vegetation metrics are from 2016.

Geography

Waterways across the Melbourne Water region, Australia.
