This wetland monitoring platform is developed and maintained by the Centre for Ecosystem Science (CES), a research unit within the School of Biological, Earth & Environmental Sciences at UNSW Sydney.
The Centre brings together researchers across a broad range of expertise — terrestrial ecology, rivers and wetlands, waterbirds, biodiversity conservation and ecosystem restoration — working to understand and protect ecosystems in Australia and around the world. Its long-term monitoring programs include the Eastern Australian Waterbird Survey, which has run since 1983.
This site draws together global satellite indicators and regional survey data to support monitoring and reporting on the condition of Ramsar wetlands of international importance.
On the map, each wetland is coloured by the long-term trend in its condition. For every indicator with a sufficiently long record, a non-parametric Mann-Kendall trend (Kendall’s τ) is calculated and direction-adjusted so that an increase counts as improvement only where it is ecologically favourable (for example, expanding bare soil or burned area is treated as decline). A wetland is shown as improving or declining by the sign of its mean statistically significant trend, otherwise stable; sites with insufficient data are shown in grey.
Delineated Ramsar polygons are based on Protected Planet, The World Database on Protected Areas (WDPA) and World Database on Other Effective Area-based Conservation Measures (WD-OECM)

Precipitation: based on the Global Precipitation Measurement ( V6 (2000-2014) and V7 (2015 – present)) which is remotely sensed satellite data of rainfall. The metric provides estimated total annual rainfall within the Ramsar polygon as well as within the catchment area ( HydroBasin level 5 )
Drought and runoff : TerraClimate climate and climatic water balance for global terrestrial surfaces which is used to calculate the average annual Palmer Drought Severity Index and Runoff within the catchment area ( HydroBasin level 5 ).
Moisture and vegetation cover : Remotely sensed Sentinel-2 MSI data used to calculate Moisture Index (B8A - B11) /(B8A + B11) and a Vegetation Index (B8-B4)/(B8+B4) within the Ramsar polygon .
Surface water : remotely sensed distribution of surface water based on the Copernicus Programme which is used to calculate the maximum annual area of surface water as well as the annual monthly average.
Fire : burned area based on the MODIS instrument onboard the Terra satellite and the Terra and Aqua satellites used the calculate the total burned areas with the Ramsar polygon at a probability greater than 0.80 and greater than 0.95.
DEA Wetlands Insight Tool : remotely sensed data combining both the Water Observations from Space and Fractional Cover summarising the relative annual area of water, green vegetation, dry vegetation and bare soil over time within the Ramsar polygon .
Geoscience Australia Water Observations : remotely sensed data of the Water Observations from Space summarising the maximum annual area of water within the Ramsar polygon .
Eastern Australian Waterbird Survey : aerial survey of waterbirds carried out since 1983 by the Centre for Ecosystem Science, UNSW. Metrics include total annual number of waterbirds and abundances of five functional response groups recorded along stratified 30-km survey bands which intersect with the Ramsar polygon .
Murray-Darling Targeted Survey : aerial survey of waterbirds carried out since 2007 at 38 important wetland and river sites in the Murray-Darling Basin.
