Biodiversity Features Ocean quahog aggregations (including offshore subtidal sands and gravels). Geodiversity Features None. Site Description The MPA proposal lies next to the Norwegian transboundary line in the northern North Sea. Potential Alternative Designations At the request of Marine Scotland, JNCC have proposed the Norwegian Boundary Sediment Plain possible MPA as a science-based alternative to the representation of ocean quahog aggregations in the Firth of Forth Banks Complex proposed MPA. If the Firth of Forth Banks Complex is designated for ocean quahog, Norwegian Boundary Sediment Plain is not required for designation as part of the MPA network. |

Human Activity Summaries
Human activities that would be impacted by designation of the site as an MPA
Table 4a. Commercial Fisheries (assuming zero displacement of fishing activity) | [ NSP] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, pelagic trawls and some otter trawls (over-15m) and nephrops trawls and other gears (under-15m vessels) operate within the NSP proposed MPA. The value of landings from the NSP area was £13,500 (over-15m vessels) and £2,200 (under-15m vessels, indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). Landings from the over-15m vessels were into Peterhead (100%). For the over-15m fleet, there was sparse activity by various trawlers in the southern part of the proposed MPA. Non- UK VMS ping data indicate that 15 non- UK vessels were active in the NSP area in 2012: 12 from Denmark; 2 from Sweden and 1 from Norway. The Swedish vessels fish with pelagic gear (pelagic trawls and purse seines) and, therefore, are unlikely to be affected by the management scenarios. Six Danish vessels fish with bottom trawl and, therefore, may be impacted by the management measures assessed under the intermediate and upper scenarios. No information on gear types used by the Norwegian vessel was available. Provisional ScotMap data do not indicate any under-15m vessel activity in the NSP proposed MPA. Management measures for the scenarios have been developed based on the sensitivity and vulnerability of the features to the pressures caused by different gear types and based on JNCC recommendations. Unlike most other sectors, the potential cost of designation on commercial fisheries is a loss or displacement of current (and future) output, caused by restrictions on fishing activities. Any decrease in output will, all else being equal, reduce the Gross Value Added ( GVA) generated by the sector and have knock-on effects on the GVA generated by those industries that supply commercial fishing vessels. The costs estimates for this sector have therefore been estimated in terms of GVA. GVA estimates have been generated by applying fleet segment-specific 'GVA/total income' ratios to the value of landings affected. The GVA ratios have been calculated using data on total income and GVA from the Sea Fish Industry Authority Multi-year Fleet Economic Performance Dataset (published March 2013). Further details on the GVA ratios and the methodology for estimating GVA and employment impacts applied are presented in Appendix C7. It is important to note that all costs presented below assume that all affected landings are lost, that is, there is no displacement of fishing activity to alternative fishing grounds. In reality, some displacement is likely to occur and hence the cost, GVA and employment impacts presented in this table are likely to overestimate the costs. |

Total costs = Sum of one-off costs and recurring costs for the site summed over the 20 year period. Average annual costs = Total costs divided by the total number of years under analysis ( i.e. 20). Present value of total costs = Total costs discounted to their current value, using a discount rate of 3.5%. Total change in GVA (2014-2033) = The change in direct GVA in the sector for the site summed over the 20 year period. Average annual change to GVA = Total change in direct GVA in the sector for the site divided by the total number of years under analysis ( i.e. 20). Present value of total change in GVA (2014-2033) = Total change in direct GVA in the sector for the site discounted to current value, using a discount rate of 3.5%. Direct and Indirect reduction in Employment = The average (mean) reduction in direct employment in the sector plus the indirect reduction in employment on the sector's suppliers. |
Table 4b. Oil and Gas | [ NSP] | ||
---|---|---|---|
There are four known hydrocarbon fields present within the boundary of the NSP proposed MPA. Four licensed blocks are present within the MPA proposal boundary, and two licence awards were granted during the 26 th UK oil and gas licensing round; blocks 16/24c and 22/4c. A total of 56 wells are present within the NSP proposed MPA, and 8 pipeline sections. All oil and gas infrastructure within the NSP proposed MPA overlaps with feature extent for ocean quahog aggregations under all scenarios. Blocks awarded during the 26 th round partially overlap the MPA proposal. There have been no significant discoveries within the NSP proposed MPA boundary. |

Ocean quahog aggregations (including offshore subtidal sands and gravels) | Provides representation for an area of the species in the only OSPAR Region it is recorded within in offshore waters adjacent to Scotland - OSPAR Region II. Norwegian boundary sediment plain is not a relatively data-rich area for the species. | Provides one of at least three recommended examples to be protected in Scotland's seas. | Not currently understood for ocean quahog. | Provides representation at the south-eastern extent of its range in OSPAR Region II in Scotland's seas. | Ocean quahog is listed as Threatened and/or Declining by the OSPAR Commission in OSPAR Region II so the MPA is expected to help increase resilience for the feature. |
