Australian National Aquatic Ecosystem (ANAE) classification for the Murray Darling Basin - Wetlands (2017)

ANAE_Wetlands is a comprehensive compilation of wetland polygon mapping for the Murray-Darling Basin using the best available jurisdiction mapping (SA, Vic, QLD, NSW), the Geofabric v2, the MDBA Wetlands GIS of the Murray-Darling Basin Series 2.0, and detailed mapping from the Namoi Catchment Management Authority, Murrumbidgee Catchment Management Authority, and Murray Wetlands Working Group. Source data sets are listed in the DataSources table in the MDB_ANAE geodatabase. Data sources range in scale from 1:,000 to 1:250,000.The interim Australian National Aquatic Ecosystem (ANAE) classification framework has been applied to all wetland polygons varying by system type (lacustrine, palustrine, riverine, estuarine). Floodplains are classified in a separate layer. Attribute values and final wetland type assignment is included in the attribute data table.CC - Attribution (CC BY) This data has been licensed under the Creative Commons Attribution 3.0 Australia Licence.

Victoria Victoria maintains an inventory of wetlands (WETLAND_CURRENT) which is designed for use in Victorian wetland projects and is subject to ongoing validation and updates. WETLAND_CURRENT can be obtained from the Department of Environment and Primary Industries (see http://www.depi.vic.gov.au/forestry-and-land-use/maps-imagery-and-data for further details). For lacustrine and palustrine aquatic ecosystems, the MDB_ANAE geodatabase is more suited to wetland projects involving other jurisdictions. While much of the data for lacustrine and palustrine wetlands was sourced from WETLAND_CURRENT, there may be some inconsistencies between MDB_ANAE geodatabase and WETLAND_CURRENT. The two datasets can be linked through the AltSrcID (MDB_ANAE geodatabase) and Wetland_No (WETLAND_CURRENT data set) fields.SA Due to the Basin-wide nature of this dataset, accuracy of final classes has not been ground truthed comprehensively, which could impact results of any analysis using this data. Therefore it is imperative that this dataset is assessed as to fitness for use in any application and decisions made about further levels of validation required. Significant care should be taken if information derived from this dataset is to guide decision making, form binding agreements regarding target setting, compliance of any form, or monitoring of achievements, this includes for the purpose of summarising areas of wetland types.
