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) | [ FSS] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, whitefish trawls, nets, lines and pelagic trawls (over-15m) and whitefish trawls and other gear (pots, nets, lines, pelagic trawl, other trawl and pots) (under-15m vessels) operate within the FSS proposed MPA. The value of catches from the FSS area was £947,000 (over-15m vessels) and £657,000 (under-15m vessels, indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). Landings from the over-15m vessels are predominantly into Scrabster (41% by value), Kinlochbervie (20%), Ullapool (14%), Peterhead (8%) and Lochinver (6%). For the over-15m fleet, nets operate in particular along the south east edge of the proposed MPA in the area of subtidal sands and gravels, while whitefish trawlers operate mainly in a central belt towards the south west of the proposed MPA over areas of ocean quahog and deep sea sponge aggregations. Non- UK VMS ping data indicate that 59 non- UK vessels were active in the FSS area in 2012: 28 from Norway; 14 from France; 5 from the Faroe Islands; 5 from Spain; 4 from Germany; and 1 from each of Denmark, Greenland and the Netherlands. The Dutch vessel fishes with pelagic gear (pelagic trawls) and therefore is unlikely to be affected by the management scenarios. 5 French vessels and 2 German vessels fish with bottom trawls and therefore may be affected by the proposed management measures under all scenarios; 1 German vessel and 5 Spanish vessels fish with lines, which may be affected under the upper scenario. No information on gear types used by the Norwegian, Faroe Islands or Greenland vessels was available. Information submitted by the French ministry indicated that 4 vessels in 2008, and 3 vessels in 2011, fished in the proposed MPA area. In 2008, these were all >40m demersal trawlers, targeting Greenland halibut, blue ling and saithe, with catches worth €0.543 million. In 2011, these comprised >40m demersal and pelagic trawlers, and <12m potters. The vessels originated from Boulonge-sur-Mer, Lorient, Fécamp and Cherbourg ports, but had their home ports at Lochinver, Boulogne-sur-Mer, Ullapool, Ijmuiden and Portbail. Between 1 and 4% of their turnover was dependent on fishing in the proposed MPA area, and they accounted for 50-66 FTE jobs on board. Provisional ScotMap data coverage does not extend as far as Shetland, therefore there is no indication of possible under-15m vessel activity in the FSS proposed MPA from this source. The cost estimates for the under-15m sector may be overestimates, as the 'under-15m' length group in the ICES rectangle landings data may include cases where information on vessel length and/or administrative port is missing from landings returns. 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. A lower scenario which excludes mobile bottom-contact gear but not static gear use on deep-sea sponge aggregations has also been included. 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. |

Table 4b. Oil and Gas | [ FSS] | ||
---|---|---|---|
The FSS proposed MPA boundary encompasses five known hydrocarbon fields that overlap with the proposed protected features. Three of these fields are currently producing (Schiehallion, Foinaven, Loyal) while the other two are under development (Laggan, Tormore). There are 69 licensed oil and gas blocks within the proposal boundary that overlap with offshore subtidal sands and gravels under all scenarios. Feature extents show that 26 of these blocks overlap with ocean quahog aggregations and 35 with offshore subtidal sands and gravels under all scenarios. Nine blocks overlap with deep sea sponge aggregations under all scenarios and 26 in the upper scenario only. Two Floating Production and Storage Offloading Vessels ( FSPO) are present in the MPA proposal boundary (Schiehallion and Petrojarl Foinaven) that overlap with offshore subtidal sands and gravels (all scenarios). One of the platforms (Petrojarl Foinaven) overlaps with ocean quahog aggregations under all scenarios and deep sea sponge aggregations under the upper scenario only. However, both platforms are within 1km of ocean quahog aggregations (all scenarios) and deep sea sponge aggregations (upper scenario only). A decommissioning programme for the Schiehallion FPSO has been approved, with work expected to begin in mid-2013. There are 69 pipeline sections within the FSS proposed MPA boundary, all of which overlap with offshore subtidal sands and gravels under all scenarios. Forty-six of the pipeline sections overlap with ocean quahog aggregations under all scenarios and deep sea sponge aggregations under the upper scenario only. A further 19 pipeline sections are present within 1km of the proposed protected features. There are 248 wells within the MPA proposal that overlap with features proposed for designation. Feature extents for deep sea sponge aggregations show overlaps with 142 wells under the upper scenario only and 11 under all scenarios. Under all scenarios all 248 wells overlap with offshore subtidal sands and gravels and 142 with ocean quahog aggregations. An additional three wells outside of the MPA boundary are within 1km of the proposed protected features. A further 16 and 36 licence awards granted under the 26 th and 27 th UK oil and gas licensing rounds respectively are present within the proposed MPA boundary that overlap with proposed protected features. Of the 26 th round awards, all 16 overlap with feature extents for offshore subtidal sands and gravels, 11 also overlap with ocean quahog aggregations and five overlap with deep sea sponge aggregations under all scenarios. Six of the 26 th round blocks also overlap with deep sea sponge aggregations under the upper scenario only. Four of the 26 th round awards are wholly within the MPA site while the rest overlap the boundary. All 36 blocks awarded in the 27 th round overlap with offshore subtidal sands and gravels under all scenarios. Twenty-seven overlap with feature extents for ocean quahog aggregations and 16 with deep sea sponge aggregations under all scenarios. Nine of the 27 th round blocks overlap with feature extents for deep sea sponge aggregations under the upper scenario only. Eighteen of the 27 th round awards lie wholly within the MPA site while the rest overlap the boundary. There have been four significant discoveries within the FSS proposed MPA boundary; all of which lie within awarded blocks. |

---|---|
Activity | Description |
Carbon Capture and Storage | There is currently no CCS activity which occurs within the boundaries of the FSS proposed MPA, nor within a 1km buffer zone. One potential hydrocarbon field (Schiehallion) overlaps with the south-western part of the 'ocean quahog aggregations' and 'offshore subtidal sands and gravels' features of the FSS proposed MPA under all scenarios (lower, intermediate and upper). Additionally, the identified potential hydrocarbon field (Schiehallion) overlaps with the deep sea sponge aggregations feature of the FSS proposed MPA under the high scenario. However, in the timescales of the project (2014-2033), it is considered that CCS will utilise existing oil and gas pipelines, where possible, between St Fergus and the Goldeneye hydrocarbon field and that possible new infrastructure (pipeline or shipping) will link the Firth of Forth to St Fergus and Teesside to an offshore hub at Goldeneye. None of these possible future CCS developments occur within the boundaries of the FSS proposed MPA, nor within a 1km buffer zone. Therefore, no cost impacts are expected. |
Recreational Boating | Two light use RYA cruising routes (from Dalgety Bay Sailing Club) overlap the deep sea sponge aggregations, ocean quahog aggregations and offshore subtidal sands and gravels features of the FSS proposed MPA. Under the lower and intermediate scenarios overlap with the deep sea sponge aggregations occurs in the north-eastern extent of the feature (for a distance of 1.7km) and the south-western extent of the feature (for a distance of 9.7km). Under the high scenario, the north-eastern cruising route overlaps the deep sea sponge aggregations for a distance of 13.4km, whilst the second cruising route intersects the centre of the deep sea sponge aggregations for a distance of 14.6km. Under all scenarios overlap with the ocean quahog aggregations feature occurs in the north-eastern extent of the feature (for a distance of 13.4km) and central extent of the feature (for a distance of 14.6km). Under all scenarios overlap with the offshore subtidal sands and gravels feature occurs in the north-eastern extent of the feature (for a distance of 30.1km) and central extent of the feature (for a distance of 34.7km). It is unlikely that there would be a significant interaction between the proposed protected features and recreational boating and so no cost impacts are expected. |
Telecom Cables | Three operational telecom cables (FARICE (2)) (in operation since 2004), SHEFA-2 Seg 7-1 and SHEFA-2 Seg5 (in operation since 2008)) overlap with the FSS proposed MPA. Two of the cables overlap with deep sea sponge aggregations (all scenarios), offshore subtidal sands and gravels (all scenarios) and ocean quahog (all scenarios). The third cable overlaps with just offshore subtidal sands and gravels (all scenarios) and ocean quahog (all scenarios). However, no cost impacts are foreseen as the site is located beyond the 12 nautical mile threshold (within which licences are required for cables). |

Deep sea sponge aggregations | Provides representation for deep sea sponge aggregations in OSPAR Region II. | Provides one of at least three recommended examples to be protected in Scotland's seas. | Not currently understood for deep sea sponge aggregations. | Provides representation of an ecologically distinct type of deep sea sponge aggregation - aggregations of Boreal Ostur. This type of deep sea sponge aggregation to date has only been recorded in the Faroe-Shetland Channel in Scotland's seas. | Deep sea sponge aggregations are considered to be Threatened and/or Declining by the OSPAR Commission in OSPAR Region II so the MPA is expected to help increase resilience for the feature. |
Ocean quahog aggregations | 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. Faroe-Shetland sponge belt 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 north-western 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. |
Offshore subtidal sands and gravels | Provides representation for Atlantic and Arctic influenced slope offshore subtidal sands and gravel habitats in OSPAR Region II. | Represents one of at least two recommended examples of Atlantic and Arctic influenced slope offshore subtidal sands and gravels to be protected in OSPAR Region II. | Not currently understood for offshore subtidal sands and gravels. | Provides representation at the north-western extent of its range on the continental slope in OSPAR Region II in Scotland's seas. | Offshore subtidal sands and gravels are fairly widely recorded across offshore waters in Scotland's seas. |
Continental slope | The possible MPA provides representation for one of two recommended areas of the Scottish continental slope to be included within the MPA network. | The Faroe-Shetland Channel slope is considered ecologically and hydrographically distinct to the Hebridean slope and so the recommendation is for at least one example of each area of the slope to be included. | Not currently understood for the continental slope. | The Faroe-Shetland Channel slope is considered ecologically and hydrographically distinct to the Hebridean slope. This possible MPA represents one example of the Faroe-Shetland Channel slope. | The continental slope occurs between Scotland's shelf and off-shelf environment. |
