Coastal and mid-land vegetation

This assessment summary component has changed from 2011.

  • The title has been expanded to better represent the component being assessed.

The original 2011 summary, grade, trend and confidence levels have been replicated here to assist comparison of changes between reporting cycles.

Coastal and mid-land terrestrial invertebrate populations

This assessment summary component has changed from 2011.

  • In 2011, 'coastal and midland terrestrial invertebrate populations' and 'upland terrestrial invertebrate populations' were combined in 'terrestrial invertebrate populations'.
