Study area Wetland extent percentage 2019/pre-clear by system Total percentage
intertidal (saltmarsh, saltflats, mangroves) (natural) lacustrine (natural) palustrine (natural) riverine
All 92.6% 100.0% 62.0% 55.1% 68.3%
Cairns Urban 78.0% - 22.2% 22.3% 55.7%
Great Sandy Strait 98.7% 100.0% 70.6% 57.6% 73.5%
Pumicestone Passage 90.1% 100.0% 49.1% 68.8% 56.5%


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.
