State and trends of quality of habitat-forming species
Saltmarshes
This component has changed since 2011.
- The component has been moved from Marine environment to Coasts
The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.
Historically decimated near urban areas in the south-east, with loss due to channeling of rivers, concretisation and drainage. Currently under threat from mangrove encroachment, invasive species, and insect control activities.
East in poor condition and declining
Mangroves
This assessment summary component has changed from 2011.
- The component has been moved from Marine environment to Coasts
The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.
Approximately 10% of Australia's mangroves were lost in 2016 due to climate pressures in northern Australian. Affected by coastal development in some areas, but increasing in extent elsewhere.
East and south-east regions in poor condition
Seagrass
This component has changed from 2011.
- The component has been moved from Marine environment to Coasts
The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.
Pressured by nutrient and sediment addition, habitat loss and severe weather events (e.g. tropical cyclones), particularly in Queensland and New South Wales.

Assessment Summary Key
Grades
Very good
Human activities or declining environmental conditions have had no or only minor impacts on habitats, species/taxa groups, physical, biogeochemical, biological or ecological processes.
Good
Human activities or declining environmental conditions have had some significant impacts on habitats, species/taxa groups, physical, biogeochemical, biological or ecological processes, but effects are not persistent or substantial on overall habitats, species/taxa groups or processes.
Poor
Human activities or declining environmental conditions have caused substantial changes to habitats, species/taxa groups, physical, biogeochemical, biological or ecological processes, resulting in persistent and substantial effects on habitats, species groups or processes.
Very poor
Human activities or declining environmental conditions have caused widespread changes to habitats, species or processes resulting in loss of habitat, species/taxa groups and ecosystem functioning.
