The population abundance of marine species indicates healthy populations and meets OSPAR threshold values in the International North Sea. Indicator(s) and (reference): B1 Bird abundance (OSPAR); Thresholds current number is ≥70% (or ≥80%) of the number in 1991-2000 (OSPAR). Bird abundance Netherlands (national); Thresholds current number ≥70% (or ≥80%) of the number in 1991-2000, or current number ≥GRP (national).

The population size of fish species indicates healthy populations and at least meets the objectives of OSPAR (vulnerable fish species) and the CFP (commercially-exploited species) in the International North Sea, and the HR in the Dutch part of the North Sea. Indicator(s) and (reference): FC1 vulnerable fish species (OSPAR); threshold: No decrease from previous period. Commercially-exploited species (CFP); threshold: SSB > MSY Btrigger (CFP), averaged over the plan period. Population (HR): Thresholds: FRP (HR).

The population sizes of harbour porpoise, harbour seal and grey seal indicate healthy populations and meet the threshold values of OSPAR (Sub-areas of the International North Sea) and the Habitats Directive (Dutch part of the North Sea). Indicator (reference) and threshold: M4 abundance and distribution of cetaceans (OSPAR); Threshold: Annual population decline <1.6% plus no decline > 30% compared to base year 1994 (OSPAR). M3 abundance and distribution of seals (OSPAR); Threshold: No decline in numbers > 1% per year (approx. 6% in the last 6 years) plus no decline > 25% compared to base year 1992 (OSPAR). Population (HR): Threshold: Harbour porpoise: 60,000, grey seal: 1000-5000, harbour seal: 2000-5000 (FRP from HR).

Breeding productivity of marine birds indicates healthy populations in the International North Sea and meets OSPAR threshold values. Indicator(s) and (reference): B3 Breeding productivity of marine birds (OSPAR); Threshold average breeding productivity over 6 years is sufficient to prevent a population decline of ≥30% over 3 generations (OSPAR). Breeding productivity of shorebirds (national): Threshold average breeding productivity is sufficient to avoid a population decline (national).

The pup production of grey seal (International North Sea sub-areas) and harbour seal (Dutch part of the Wadden Sea) indicates healthy populations and meets the OSPAR threshold value for grey seal. Indicator(s) and (reference): OSPAR: M5 Grey seal pup production Trilateral Wadden consultations: Harbour seal pup production Thresholds: OSPAR: The grey seal birth rate must not decrease by more than 1% annually since the last assessment and 25% since 1992 (OSPAR) Trilateral Wadden consultations: Not available
