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.

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.
