Connectivity

This component has changed from 2011.

  • Connectivity is being reported on in Coasts as well as Marine environment.

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

Data poor, but believed to be worsening due to habitat fragmentation and anthropogenic change to mechanisms of dispersal. Connectivity increased for those species that can use ships and other vessels as a vector.

Nesting, roosting and nursing sites

This component has changed from 2011.

  • It 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.

Under increasing threat from a range of human activities and climate-related pressures.

Trophic structures and relationships

This component has changed from 2011.

  • Trophic structures and relationships has been assessed in both Marine environment and Coasts.

Modified by overharvesting and nutrient enrichment. Improving where fishing activity and urban/agricultural inputs are well managed.

Microbial processes and nutrient cycling

This component has changed from 2011.

  • 'Microbial processes' has been assessed in both Marine environment and Coasts.
  • It has been expanded to include nutrient cycling for Coasts.

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

Data poor. Sensitive to human impacts, particularly nutrient and contaminant inputs. May be useful indicators for biomonitoring.
