WKP6

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.
