Note that these totals may be lower than the Queensland totals due to incomplete coverage of study areas.


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.
