Polygons showing the extent of wetlands in Victoria prior to European settlement. Wetlands are classified into primary categories based on water regimes. The polygon boundaries were derived from digitizing marked up aerial photography interpretation.

Polygons showing the extent of wetlands in Victoria prior to European settlement. Includes all wetlands from Wetland_1788 and naturally occurring wetlands that were added to the updated current wetland extent (WETLAND_CURRENT). Where available original Corrick classification (primary categories based on water and salinity regimes) were retained. The polygon boundaries were derived from aerial photography interpretation. The most recent update to this database was in 2021.

Polygons showing the extent and types of wetlands in Victoria. The 2025 Victorian Wetland Inventory (Current) has undergone a significant revision that increases the comprehensiveness of the state's geospatial wetland inventory. Excluding dams and storages < 8ha (mostly farm dams), the number of mapped wetland polygons has approximately doubled to 64,132, adding approx. 317,000 ha additional wetland area. With the inclusion of the many small dams/storages the inventory now contains 427,540 polygons (1,101,368 ha). The revision builds on the previous inventory by importing additional wetland boundaries from other state sources including VicMAP Hydro, regional mapping by Catchment Management Authorities, Melbourne Water, saltmarsh and estuarine vegetation mapping and mapping of dams and storages. These sources were also used to update some existing inventory boundaries where the alternative was considered a more accurate representation of the wetland extent. Attributes used by the Victorian Wetland Classification Framework including system type, salinity regime, water regime, water source, dominant vegetation were populated (with assumed values where necessary) to permit all wetlands to be classified to their wetland type. Confidence scores were added reflecting the strength of evidence (low, medium, high, certain) for each attribute. Fields were added to improve traceability of wetland mapping to the various data sources.

This dataset is a copy of the WETLAND_CURRENT dataset prior to the 2025 update. Polygons showing the extent and types of wetlands in Victoria. WETLAND_CURRENT was created in 2013 and was derived from WETLAND_1994 (the state's first wetland geospatial inventory) and several local and regional wetland datasets. A number of updates have occurred to the dataset during 2014, 2017 and 2021. The 2014 update incorporated new regional mapping, some supplementary mapping and repositioning of planimetrically inaccurate wetlands. Supplementary mapping involved identifying and delineating wetlands which had not previously been mapped, but did not modify the extent of existing wetlands. It was undertaken primarily using aerial photograph interpretation (photos from 2007 to 2011) supplemented with existing geospatial datasets that provided context and informed the identification of wetland boundaries (e.g. vegetation mapping, topography). Wetlands were classified (according to the new classification framework) into primary categories based on wetland system type, salinity regime, water regime, water source, dominant vegetation and wetland origin. The 2017 update improved the accuracy of the layer by updating wetland mapping and attributes in the Melbourne area and for alpine bogs and fens in East and West Gippsland catchment regions. It also involved correcting inaccurate classification attributes and correcting wetland polygons for individual wetlands based on new data and feedback from wetland inventory users. The 2021 update incorporates new mapping and refinements to existing wetland polygons for several regional wetland datasets. These include Tootgarook Swamp, Alpine Bogs, Mitchell River Floodplain Wetlands, Melbourne Water Billabongs and Mallee CMA Wetlands. The dataset currently consists of 38,799 polygons totalling 784,120 ha.

Polygons defining Ramsar wetland areas in Victoria. The Ramsar Convention of Wetlands of International Importance, to which Australia is a signatory, requires contracting parties to designate wetlands of international significance within their territory for listing under the convention. This layer is based on RAMSAR100 but has been realigned and updated to improve its accuracy. It has been updated to match current VICMAP parcel, road, hydro and water area data as well as using high-resolution digital aerial photography to improve its precision to 1:25 000.

This layer contains Victorian wetlands listed in the 3rd Edition of 'A Directory of Important Wetlands of Australia' (2001). Descriptions for each wetland are available in the directory which is available on the Environment Austalia website at: http://www.ea.gov.au/water/wetlands/database/index.html These wetlands are derived from the WETLAND_1994 CGDL layer, hydrological CGDL layer and other sources such as topographic maps. The 2017 update of the Victorian Wetland Inventory (Current) resulted in improved accuracy of the boundary of a number of wetlands, based on on-ground mapping. WETLAND_CURRENT provided the source data to improve the WETLANDDIR dataset.

Wetland landscape profiles represent a regionalisation of wetlands at the landscape scale. They are based on variation in regional wetland vegetation as described in Appendix 3 of Department of Sustainability and Environment (2012) Index of Wetland Condition assessment of wetland vegetation update - December 2012.
