This is a polygon coverage representing the wetlands cited in the "A Directory of Important Wetlands in Australia" Third Edition (EA, 2001), plus various additions for wetlands listed after 2001.

This coverage is a compilation of various data sources and has been collected using a variety of methods. This dataset should therefore be used as an indicative guide only to wetland boundaries and locations. The data has been collated by the Australian Government Department of the Environment and Energy from various datasets including those supplied by the relevant State agencies.

State agency contributors include the Queensland Environmental Protection Authority, NSW Department of Environment and Conservation and the Victorian Department of Sustainability and Environment.

For the identification of wetland boundaries or locations in regard to the compliance of activities with relevant State legislation, the relevant State authority should be contacted to obtain the most recent and accurate wetland boundary information available.

The criteria for the definition of a wetland used in this dataset is that adopted by the Ramsar Convention, namely: "areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six meters."

Attributes in the dataset include:

WNAME: the name of the wetland site as listed in the Directory.

REFCODE: an individual reference number including a cross reference to the State in which it occurs. The first 2-3 characters relate to the State or Territory of origin followed by the 3 digit sequential wetland numeric code. (eg. "NSW001": NSW=New South Wales; 001=wetland number).

SOURCE: the data source for the polygon.

FEAT_CODE: description of the waterbody's hydrographic feature (eg. 'lake', 'swamp'). This attribute is derived from the TOPO250K.WATERBOD coverage.

STATE: the State or Territory in which the waterbody occurs.

SUPPLY_BY: the name of the agency that supplied the boundary of a wetland and date of supply to the Department

This data was updated on 23/03/2010. The wetlands of "Lake Cowal/Wilbertroy Wetlands" (Refcode: NSW040) has an additional small polygon about 600 km away. It is considered as an error. This additional small polygon was removed.
