Disclaimer

All figures exclude artificial and highly modified wetlands.

The total percentage figure includes slightly modified wetlands.

Figures 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.

Figures may change over time as mapping approaches improve.
