Disclaimer

Areas do not include marine or estuarine waters but do include estuarine wetland vegetation
(e.g. mangroves and tidal flats).

All statistics are approximate and generated based on data transformed to a customised Albers equal-area projection, thus allowing wetland extent change for different regions of Queensland to be comparable.

Areas may change over time as mapping approaches improve.

Totals may not match the sum of individually displayed figures due to the rounding of displayed figures.

Note: Wildlife statistics are based on information that has been submitted to the DETSI WildNet database and converted to a 10km² grid. The grid information has been intersected with the mapping polygons to determine the species lists. Click here to view the species grid metadata.

Information from WildNet can also be accessed via Wildlife Online and WetlandMaps.

Rare or threatened includes species listed as extinct, extinct in the wild, critically endangered, endangered, vulnerable or conservation dependent under either the Nature Conservation Act or Environment Protection and Biodiversity Conservation Act
