2 Indicators used in the monitoring system

A set of state and pressure indicators are used to monitor conditions in the management plan areas. The results are reported to the management plan system. The results and further information about the indicators are also available at https://miljostatus.miljodirektoratet.no/tema/hav-og-kyst/havindikatorer/ (in Norwegian only).
