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) | [ FOF] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, dredgers, otter trawls (nephrops, whitefish and other) and whitefish seines (over-15m vessels) and nephrops trawls, pots, dredgers, other trawls, whitefish trawls, hand fishing, lines and nets (under-15m vessels) operate within the FOF proposed MPA. The value of catches from the FOF area was £483,000 (over-15m vessels) and £248,000 (under-15m vessels, indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). For the over-15m fleet, dredgers operate in particular in the western component of FOF, with whitefish trawls and other trawls operating across the area. The feature extents for ocean quahog and offshore subtidal sands and gravels extend across the whole proposed MPA boundary in the intermediate and upper scenarios. Dredging, trawling, seining and static gear use therefore overlap with both proposed protected features under both the intermediate and upper scenarios. Management 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 advice. Using this information, the potential cost impacts of management measures have been assessed for trawls and dredges. Non- UK VMS ping data indicate that 7 non- UK vessels were active in the FOF area in 2012, all from Denmark. Based on the EU vessel register, it appears that two of these vessels fish with bottom trawls and therefore would be impacted by the management measures assessed under the intermediate and upper scenarios. Provisional ScotMap data indicate that the annual average earnings from the FOF proposed MPA was £191,800, with over 70% of this from pots (predominantly for lobster). The spatial distribution of value from the under-15m ScotMap data indicates that the majority of value in the FOF proposed MPA and surrounding area is derived from closer inshore in the Firth of Forth area, indicating that the estimates of value of landings from the ICES rectangle data is likely to over-estimate the impact on the under-15m sector. The coverage for ScotMap interviews in the region was 85.2% (total value of reported landings from the Fisheries Information Network for those vessels included in the ScotMap value analysis expressed as a percentage of the total reported landings for all vessels <15m). Therefore the ScotMap estimate is likely to slightly under-represent the value of fishing by under-15m vessels, but the spatial representation of the value of fishing is fairly robust due to the high level of coverage. 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. Energy Generation | [ FOF] | ||
---|---|---|---|
There are no energy generation activities currently operating within the FOF proposed MPA boundary or corresponding buffer zones. Thus, economic costs and management measures associated with energy generation in this proposed MPA are described in light of known possible future developments. In 2012, Seagreen Wind Energy Limited (Seagreen) submitted separate applications to the Scottish Government for consent to construct two offshore wind farms (Project Alpha and Project Bravo, 525MW each) in the Firth of Forth Offshore Wind Zone (Phase 1). Project Alpha and Project Bravo overlap the western and northern parts of the FOF proposed MPA boundary, respectively. Buffer zones (1km) around possible export cable routes from these potential wind farm developments could overlap the FOF proposed MPA boundary. Nevertheless, any associated costs of Phase 1 are considered sunk as the application process has the potential to be concluded prior to 2014. Similarly, the consent application has been submitted for the Neart Na Gaoithe (Mainstream Renewable Power) wind farm development which lies within a 5km buffer zone around the proposed MPA, but any associated costs are effectively sunk (as above). Seagreen's plans are ongoing regarding the development of two further areas of the Firth of Forth Offshore Wind Zone (Phases 2 and 3, up to 2.6GW combined capacity). Phase 2 is planned to comprise three wind farms (Seagreen Charlie, Seagreen Delta and Seagreen Echo) and Phase 3 is planned to comprise two wind farms (Seagreen Foxtrot and Seagreen Golf). The areas considered for Phases 2 and 3 overlap the southern and western parts of the FOF proposed MPA. Approximately 57.4km 2 (6.2%) of Phase 2 would overlap the western and southern parts and approximately 502.8 km 2 (67.2%) of Phase 3 would overlap the western part. Additional licence application costs may be incurred in order to assess potential impacts to MPA features (ocean quahog aggregations ( OSPAR listed) and offshore subtidal sands and gravels ( UK BAP listed)) for Phases 2 and 3 under all scenarios, as well as additional survey costs. Therefore, should Seagreen successfully obtain permission(s) to construct Phases 2 and 3 within the FOF proposed MPA boundary, additional management measures may be required. Buffer zones (1km) around possible export cable routes from Firth of Forth Offshore Wind Zone developments overlap ocean quahog aggregations and offshore subtidal sands and gravels within the FOF proposed MPA boundary. The Inch Cape (Repsol Nuevas Energías UK) wind farm development (pre-application) lies within a 5km buffer zone around the proposed MPA and, therefore, may incur additional costs to assess the potential impacts to the proposed protected features (ocean quahog aggregations and offshore subtidal sands and gravels) under the intermediate and upper scenarios. It should be noted that additional cost impacts could also arise as a result of consenting delays. The cost impacts and uncertainty associated with MPA designation may affect investor confidence. |

Table 4c. Military | [ FOF] | ||
---|---|---|---|
Two military practice areas: St Andrews (D609; sonobuoy, missile and firing) and area D609 (firing danger area) overlap with the northern part of the FOF proposed MPA. Both of these military practice areas overlap with ocean quahog aggregations (all scenarios) and offshore subtidal sands and gravels (all scenarios). Three military practice areas: Firth of Forth (middle) (X5641), Firth of Forth outer (outer) (X5642) and a submarine exercise area overlap with the western component of the FOF proposed MPA. All three military practice areas overlap with ocean quahog aggregations (all scenarios) and offshore subtidal sands and gravels (all scenarios). Five military practice areas: St Andrews (D609, sonobuoy, missile, firing), Firth of Forth (outer) (general practice area), X5642 (firing danger area), D609 (firing danger area) and a submarine exercise area overlap with the southern part of the FOF proposed MPA. All of these military practice areas overlap with ocean quahog aggregations (all scenarios) and offshore subtidal sands and gravels (all scenarios). Although the proposed protected features are vulnerable to certain MoD activities, no management options are proposed. This is because it is assumed that management relating to MoD activity will be coordinated through the MoD's Maritime Environmental Sustainability Appraisal Tool ( MESAT) which the MoD uses to assist in meeting its environmental obligations. This process will include operational guidance to reduce significant impacts of military activities on MPAs. It is assumed that the MoD will incur additional costs in adjusting MESAT and other MoD environmental assessment tools in order to consider whether its activities will impact on the conservation objectives of MPAs and also incur additional costs in adjusting electronic charts to consider MPAs. However, these costs will be incurred at national level and hence no site-specific cost assessments have been made. |

Human activities that are present but which would be unaffected by designation of the site as an MPA
Table 6. Human Activities that are Present but which would be Unaffected by Designation of the Site as an MPA [ FOF] | |
---|---|
Activity | Description |
Oil and Gas | Two abandoned oil wells are present in the northern part of the FOF proposed MPA boundary; wells 26/14-01 and 26/08-01. There are no awarded licence blocks currently within any part of the FOF proposed MPA boundary. The feature extents for both ocean quahog aggregations and offshore subtidal sands and gravels under the lower, intermediate and upper scenarios overlap with the abandoned wells and licence blocks, although no cost impacts are foreseen as there is no current or future activity anticipated. |
Power Interconnectors | One future power interconnector (Eastern HVDC Link) overlaps with the southern part of the FOF proposed MPA for a distance of 26.2km and one future power interconnector (Norway-England connector) potentially overlaps with the western part of the FOF proposed MPA for a distance of 5.5km. Both these future power interconnectors overlap with ocean quahog aggregations (all scenarios) and offshore subtidal sands and gravels (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). |
Recreational Boating | Two medium RYA cruising routes ( RYA Route/RYA Scotland and RYA North East Region) overlap with the 'ocean quahog aggregations' (all scenarios) and the 'offshore subtidal sands and gravels' (all scenarios) feature extents in the southern and western parts of the FOF proposed MPA for a length of 28km and 66km, respectively. It is unlikely there would be a significant interaction between the ocean quahog aggregations or the offshore subtidal sands and gravels features and recreational boating and so no cost impacts are expected. |

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. Firth of Forth Banks Complex is 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-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 a range of different types of offshore subtidal sand and gravel habitats on the continental shelf in OSPAR Region II. Firth of Forth Banks Complex is a relatively data-rich area for the habitat. | Provides one of at least two recommended examples to be protected on the continental shelf in OSPAR Region II in Scotland's seas. | Not currently understood for offshore subtidal sands and gravels. | Provides representation at the south-western extent of its range on the continental shelf in OSPAR Region II in Scotland's seas. | Offshore subtidal sands and gravels are widely distributed across offshore waters in Scotland's seas. |
Shelf banks and mounds | Provides representation for shelf bank and mound features considered to be of wider functional significance to the health and diversity of Scotland's seas, e.g. seabird and marine mammal foraging grounds. | Provides representation for one of at least two recommended areas to be included in the MPA network for shelf banks and mounds considered to be of wider functional significance in Scotland's seas. | The shelf banks and mounds in the Firth of Forth Banks area harbour relatively large numbers of sandeel, which are important for foraging seabirds and marine mammals. The banks also impinge on local current systems, increasing mixing in the water column and subsequently primary production in the area. | Provides representation at the south-western extent of the range of the feature in OSPAR Region II in Scotland's seas. | Shelf banks and mounds are fairly widely recorded across Scotland's seas. |
