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) [ BHT]

According to VMS-based estimates and ICES rectangle landings statistics, pelagic trawls, otter trawls and lines (over-15m vessels) and whitefish trawls, pelagic trawls, lines and a small amount of pots and nephrops trawls (under-15m vessels) operate within the BHT proposed MPA ( UK vessels). The value of catches from the BHT area for over-15m vessels ( VMS data) cannot be disclosed as there were fewer than 5 vessels. The value of catches for under-15m vessels was £563,000 (indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). For the over-15m fleet, lines and whitefish trawls operate in particular in the eastern part of the proposed MPA across the area of offshore subtidal sands and gravels. Landings from the over-15m vessels are predominantly made into Peterhead (36% by value), unspecified Norwegian port(s) (13%) and Egersound (12%).

Seamount communities are in the western part of the proposed MPA in the seamount area, with burrowed mud, offshore deep sea muds, offshore subtidal sands and gravels in the central and eastern part. 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 does not exclude static gear use on seamount communities has also been included.

Non- UK VMS ping data indicate that 84 foreign vessels were active in the BHT area in 2012: 32 from Norway; 24 from Ireland; 11 from France; 8 from the Netherlands; 6 from Spain, and 1 from each of Denmark, the Faroe Islands and Germany. The majority are pelagic trawls or purse seines and therefore are unlikely to be affected by management measures under any scenario. There were 6 French vessels fishing with bottom trawl, 4 Irish vessels fishing with bottom trawl or seine; and 1 Danish vessel fishing with bottom trawl, which may be affected by the management measures assessed under all scenarios. Six Spanish vessels fish with nets, and could be impacted under the intermediate and upper scenarios. No information on gear types used by the Norwegian, Greenland or Faroe Islands vessels was available.

Information submitted by the French ministry indicated that 12 vessels in 2008, and 10 vessels in 2011, fished in the proposed MPA area. They were predominantly demersal trawlers, targeting anglerfish, black scabbardfish, grenadiers and hake, with catches worth €1.639 million (in 2011). The vessels originate from Lorient, Concarneau and Fécamp ports, but have their home ports at Lochinver, Lorient, Concarneau, Killybegs and Ijmuiden. 8% of their turnover is dependent on fishing in the proposed MPA area, and they account for 122 FTE jobs on board.

Provisional ScotMap data do not indicate any under-15m vessel activity in the BHT proposed MPA. 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.

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. Military [ BHT]

Five military practice areas: Fleet Exercise Area ( PEXA X5501; miscellaneous fleet exercises) and four submarine exercise areas overlap with the BHT proposed MPA.

The Fleet Exercise Area overlaps with burrowed mud, offshore deep sea muds, offshore subtidal sands and gravels, orange roughy and seamount communities (all scenarios). All submarine exercise areas overlap with burrowed mud and offshore deep sea muds (all scenarios). One submarine area also overlaps with offshore subtidal sands and gravels (all scenarios) whilst the fourth submarine area overlaps with orange roughy and seamount communities (all scenarios).

The features proposed for designation which overlap with the military practice areas have not been described as vulnerable to MoD activities in this proposed MPA. 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.

Table 4c. Oil and Gas [ BHT]
The BHT proposed MPA encompasses two abandoned oil wells and a number of oil and gas licence blocks in quadrant 132 that were awarded to the Parkmead Group in the 27 th UKCS licensing round. Licence blocks 8, 9, 13 and 14 are located within the MPA boundary, while a small northerly section of the MPA proposal also overlaps with licence blocks 3 and 4 and blocks 18 and 19 overlap the southern section of the MPA proposal. Under all scenarios, feature extents for burrowed mud and offshore deep sea muds overlap with the awarded licence blocks.

A reduction in employment can generate a wide range of social impacts which, in turn, can generate a range of short and long term costs for wider society and the public purse:
  • Healt h (increase in illness, mental stress, loss of self esteem
and risk of depression);
  • Increase in crime; and
  • Reduction in f u ture emp lo y me n t prospects/future earnings.
Support to retrain those affected and for the promotion of new small businesses in fisheries dependent areas.
Loss of value of catches from non- UK vessels using bottom contact gears in the proposed MPA (France (6 vessels), Spain (6 vessels), Ireland (4 vessels), Denmark (1 vessel), and possibly Norway (32 vessels) and Faroe Islands (1 vessel)) Not quantified Employment - loss of foreign jobs from reduced landings.
Displacement Effects Not quantified Quantified impact on jobs assume worst case scenario ( i.e. no redistribution of effort). In reality displacement effects likely to occur with socio-economic consequences:
  • Empl o y m e nt - reduced employment due to changes in costs and earnings profile of vessels ( e.g. increased fuel costs, gear development and adaption costs, additional quota costs);
  • Conflict/Loss of social cohesion - diminishing fishing grounds may increase conflict with other vessels/gear types, increase social tensions within fishing communities and lead to a loss of social cohesion among fleets. Could also lead to increased operating costs as a result of lost or damaged gear. Equally, gear conflict could reduce where gears are restricted/prohibited;
  • Healt h - increased risks to the safety of fishers and vessels and increased stress due to moving to lesser known areas;
  • E n v ironmental - increased impact in targeting new areas, longer streaming times and increased fuel consumption; and
  • Cul t ur e a nd her i tag e - change in traditional fishing patterns/ activities.

Potential Contribution of the Site to an Ecologically-Coherent Network

Table 8. Overview of Features Proposed for Designation and how these contribute to an Ecologically Coherent Network of MPAs [ BHT]
Feature Name Representation Replication Linkages Geographic Range
and Variation
Resilience
Burrowed mud Provides representation for the seapens and burrowing megafauna type of burrowed mud in OSPAR Region V at the northern extent of its geographical range on the Hebridean slope. Makes a contribution to one of at least two recommended areas of this type of burrowed mud in OSPAR Region V in Scotland's seas. Not currently understood for burrowed mud. Provides representation at the southern extent of its range on the continental slope and off the shelf in OSPAR Region V in Scotland's seas. Burrowed mud is considered to be Threatened and/or Declining by the OSPAR Commission in OSPAR Region V so the MPA is expected to help increase resilience for the feature.
Offshore deep sea muds Provides representation for Atlantic-influenced offshore deep sea mud habitats on the slope in OSPAR Region V. Represents one of at least two examples of slope Atlantic-influenced offshore deep sea mud habitats recommended for protection in OSPAR Region V. Not currently understood for offshore deep sea muds. Provides representation of Atlantic influenced offshore deep sea muds at the southern extent of their range in OSPAR Region V. Offshore deep sea muds are fairly widely recorded across offshore waters in Scotland's seas
Offshore subtidal sands and gravels Provides representation for Atlantic-influenced offshore subtidal sand and gravel habitats predominantly on the slope in OSPAR Region V, but also to a small extent on the shelf in OSPAR Region III. It represents one of at least two recommended examples of Atlantic influenced slope and shelf offshore, subtidal sand and gravel habitats to be protected in OSPAR Regions V and III respectively. Not currently understood for offshore subtidal sands and gravels. Provides representation at the southern extent of its range on the continental slope and on the shelf in OSPAR Regions V & III respectively in Scotland's seas. Offshore subtidal sands and gravels are fairly widely recorded across offshore waters in Scotland's seas.
Orange roughy Provides representation for the only area of significance to the life history of orange roughy in Scotland's seas - The Hebrides Terrace Seamount. N/a - provides representation for the only area of significance to the life history of orange roughy in Scotland's seas - The Hebrides Terrace Seamount. The Hebrides Terrace Seamount is considered an important spawning area for orange roughy in Scotland's seas. N/a - provides representation for the only area of significance to the life history of orange roughy in Scotland's seas - The Hebrides Terrace Seamount. Orange roughy are considered Threatened and/or Declining by the OSPAR Commission in OSPAR Region V so the MPA is expected to help increase resilience for the feature.
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 Hebridean slope is considered ecologically and hydrographically distinct to the Faroe-Shetland Channel 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 Hebridean slope is considered ecologically and hydrographically distinct to the Faroe-Shetland Channel slope. This possible MPA represents one example of the Hebridean slope. The continental slope occurs between Scotland's shelf and off-shelf environment.
Seamount communities Provides representation for Seamount communities in OSPAR Region V. Provides one of at least three recommended examples to be protected in Scotland's seas. Not currently understood for seamount communities. There are three seamounts recorded in Scotland's seas and these only occur within OSPAR Region V. MPA recommendations, considered alongside the existing MPA network, will mean the inclusion of all three seamounts in Scotland's seas in the resultant MPA network. Seamount communities are considered to be Threatened and/or Declining by the OSPAR Commission in OSPAR Region V so the MPA is expected to help increase resilience for the feature.
Seamounts Provides representation for Seamounts in OSPAR Region V. Provides one of at least two recommended examples to be protected in Scotland's seas. The Hebrides Terrace Seamount is considered to be of wider functional significance to the health and diversity of Scotland's seas, e.g. enhanced biodiversity resulting from mixing caused by the interaction between the seamount and oceanic currents, increased productivity, and as feeding grounds for fish and marine mammals. There are three seamounts recorded in Scotland's seas and these only occur within OSPAR Region V. MPA recommendations, considered alongside the existing MPA network, will mean the inclusion of all three seamounts in Scotland's seas in the resultant MPA network. Seamounts are only distributed in OSPAR Region V in Scotland's seas.
