Estuary stressor
Mud content information
What do the grades mean?
Mud content refers to the amount of fine silt and clay particles (collectively called ‘mud’) that are present in the estuary sandflats. This figure shows (mean) annual mud content measured at the monitoring site. The annual values are assessed against custom, national guidelines that indicate increasingly negative impacts on the macrofaunal community.
-
≤3%
Ecology is not negatively impacted.
-
3-10%
The diversity of the macrofauna community is slightly reduced.
-
10-30%
The diversity of the macrofauna community is reduced and less resilient to disturbance.
-
30-60%
The macrofauna community is unbalanced and dominated by a small number of tolerant species.
-
>60%
The macrofauna community is degraded.

What do the grades mean?
This figure shows the (mean) annual contaminant concentration measured in the sediments of the monitored site. The annual values are assessed against the ANZG 2018 guidelines by default, and you can choose to view them assessed against several additional, more conservative guidelines. All of the guidelines show how likely it is that the contaminant is having negative ecological impacts. See the Contaminants factsheet for more information.
- Ecological impacts unlikely
- Ecological impacts possible
- Ecological impacts probable
