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) [ SMI]

According to VMS-based estimates and ICES rectangle landings statistics, Nephrops trawls, whitefish trawls, dredges, pots and other trawls (over-15m) and pots, whitefish and nephrops trawls, dredges and other gears (under-15m vessels) operate within the SMI proposed MPA. The value of catches from the SMI area was £1.07 million (over-15m vessels) and £722,000 (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 Mallaig (89%), with a small amount to Oban (4%), Northbay (2%) and Barra (2%). For the over-15m fleet, nephrops trawlers, whitefish trawlers and dredgers in particular operated across the whole proposed MPA over areas of burrowed mud and circalittoral sand and mud communities, while pots operated across the western part mainly over areas of northern sea fan and sponge communities.

Provisional ScotMap data indicate that the annual average earnings from the SMI proposed MPA was £720,600, with 65% of this from pots and over 30% from Nephrops trawls. The ICES rectangle estimate for the cost impact on <15m nephrops trawls is comparable to the estimated value of earnings from the area from ScotMap (£0.23 million), and for dredges is likely to be an over-estimate (ScotMap value is £0.01 million). The coverage for ScotMap interviews in the region was 71.9% (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, and the spatial representation of the value of fishing is less robust than in regions where coverage is higher.

VMS data indicate that there are no foreign vessels fishing within the SMI 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 SNH 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.

Table 4b. Military [ SMI]

Nine military practice areas (Hawes (X5635), Eigg (X5636), Rhum (X5707) and Canna (X5708), and five submarine exercise areas) overlap with the SMI proposed MPA.

The military practice areas Hawes (X5635), Eigg (X5636), Rhum (X5707) and Canna (X5708) overlap with Black Guillemot (all scenarios), burrowed mud (all scenarios), circalittoral sand and mud communities (all scenarios), northern feather star aggregations on mixed substrate (all scenarios) and shelf deeps (all scenarios). Rhum (X5707) and Canna (X5708) also overlap with northern sea fan and sponge communities (all scenarios), fan mussel aggregations (all scenarios), white cluster anemone (all scenarios) and horse mussel beds (Canna - all scenarios, Rhum - high scenario only). Hawes (X5635) also overlaps with northern sea fan and sponge communities (all scenarios).

The five submarine exercise areas overlap with the features of the SMI proposed MPA to varying degrees under the different extent scenarios.

The features and associated habitats which overlap with military activities 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. Ports and Harbours [ SMI]
There is one port/harbour (Canna) within the SMI proposed MPA boundary. Canna (1km buffer) overlaps with feature extents for black guillemot, circalittoral sand and mud communities, northern sea fan and sponge communities, shelf deeps and the white cluster anemone under all scenarios. The MPA feature burrowed mud overlaps the 1km buffer of Canna under the intermediate and upper scenarios only. Therefore, management costs may be incurred under the assumption that small ports/harbours will undergo one new development within the relevant time frame (2014-2033), assumed for the year 2024.

Table 4d. Recreational Boating [ SMI]

There are nine recreational boating cruising routes that intersect with the\s SMI proposed MPA; four light traffic and five medium traffic routes. Vessels transiting cruising routes are not assessed as requiring any additional management measures.

Under the upper scenario, there are seven anchorages for recreational boating that overlap with features proposed for protection within the MPA proposal boundary, overlapping with black guillemot, burrowed mud and northern sea fan and sponge communities. Ten Crown Estate mooring points are also present that overlap with the feature extent for black guillemot.

Under the intermediate and lower scenarios, SNH have identified some overlaps between anchorages at Canna harbour and basking sharks, although generally the interaction between basking sharks and anchorages is not deemed significant.

Human activities that would benefit from designation of the site as an MPA

Table 5. Human Activities that would Benefit from Designation of the Site as an MPA [ SMI]
Activity Description Lower Estimate Intermediate Estimate Upper Estimate
Tourism Coastal areas are well represented when considering the locations of various tourist related sites within Scotland with a range of site types present in all regions including the North West. Where significant impacts to recreational boating or water sports have been identified for the site, there could also be consequential impacts on tourism. Tourism may benefit from the designation of the MPA as an added attraction to the destination. In addition, there may also be indirect benefits to tourism as a result of benefits to some water sports activities, e.g. recreational angling and diving. The intermediate management measures applied to sector activities will result in an increase of the beneficial impacts seen in the lower estimate. The upper management measures applied to sector activities will result in an increase of the beneficial impacts seen in the lower and intermediate estimates.
Water Sports - Scuba Diving There is one scenic boat dive location within the\s SMI proposed MPA (Sgeir a Phuirt). This site overlaps with 'Black guillemot' under all scenarios and 'Burrowed mud' under the intermediate and upper scenarios. No management restrictions upon this activity are required. The added protection offered by an MPA designation and management measures placed upon sector activities may increase the aesthetic attraction of the dive sites through an improved marine ecosystem and a reduction in degradation to the wreck sites. The intermediate management measures applied to sector activities will result in an increase of the beneficial impacts seen in the lower estimate. The upper management measures applied to sector activities will result in an increase of the beneficial impacts seen in the lower and intermediate estimates.
Water Sports - Sea Angling Sea angling is carried out along most of the Scottish coastline within 6nm ( SSACN). The SMI proposed MPA is a coastal site with less than 50% of the site is located within 6nm of the UK coastline. The features that which overlap with this activity are 'Black Guillemot', 'Burrowed Mud', Circalittoral sand and mud communities', Northern Feature start aggregations on mixed substrata', Northern Sea fan and sponge communities' and 'Shelf deeps' under all scenarios. No management restrictions upon this activity are required. Sea anglers could benefit from any on-site positive effects resulting from the MPA designation and corresponding management restrictions on sector activities including an increase in the size and diversity of species which in turn is expected to increase the attraction of a site for anglers (Fletcher et al. 2012). The intermediate management measures applied to sector activities will result in an increase of the beneficial impacts seen in the lower estimate. The upper management measures applied to sector activities will result in an increase of the beneficial impacts seen in the lower and intermediate estimates.

Lower: 0.0 jobs
Intermediate: 3.3 jobs
Upper: 11.5 jobs
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.
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
  • Culture and heritage - change in traditional fishing patterns/ activities.

Impacts: xxx - significant negative effect; xx - possible negative effects; x - minimal negative effect, if any; 0 - no noticeable effect expected.
* These estimates assume zero displacement of fishing activity and hence are likely to overestimate the costs.

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 [ SMI]
Feature Name Representation Replication Linkages Geographic Range
and Variation
Resilience
Burrowed mud Provides representation of seapens and burrowing megafauna and tall seapen in burrowing mud in OSPAR Region III. Represents one of five areas of seapens and burrowing megafauna and one of three areas of tall seapen in Scottish seas. Not currently understood for burrowed mud. Burrowed mud occurs within a range of environments. It occurs in OSPAR Regions II, III and V. The proposed MPA and others within the network will represent the different components of burrowed mud and its geographic range and variation. Seapens and burrowing megafauna are listed by OSPAR as threatened and/or declining. The MPA area may increase resilience.
Horse mussel beds Provides representation for horse mussel beds in OSPAR Region III. Represents one of four recommended areas for horse mussel beds in Scottish seas. Not currently understood for horse mussel beds. No information available. Horse mussel beds are listed as threatened and/or declining by the OSPAR commission. The MPA may increase resilience.
Northern sea fan and sponge communities Provides representation of northern sea-fan and sponge communities in OSPAR Region III. No information available. No information available. No information available.
Fan mussel aggregations Provides representation for the only known fan mussel aggregation in Scottish seas and the largest in UK waters, found in OSPAR Region III. Represents the only known fan mussel aggregation in Scottish seas. Not currently understood for fan mussel aggregations. The MPA area contains the only known example of this habitat in Scotland's seas. Considered to be threatened and declining in Scotland's seas. The MPA area may increase resilience. The implementation of one more example should be aimed for.
Northern feather star aggregations on mixed substrata Provides representation of northern feather star aggregations on mixed substrata in OSPAR Region III. Represents one of three recommended areas for northern feather star aggregations on mixed substrata in OSPAR Region III. Not currently understood for Northern feather star aggregations on mixed substrata. All records of Northern feather star aggregations on mixed substrata are from OSPAR Region III. No information available.
Black guillemot Provides representation of black guillemot in OSPAR Region II. Represents one of six areas representing black guillemot. Not currently understood for black guillemot. The MPA area represents a relatively sheltered example of black guillemot within the most southerly part of it's range. Although not listed by OSPAR as threatened and/or declining, there is evidence of decline. The potential MPA areas may increase resilience.
Shelf deeps Provides a functionally significant representation of shelf deeps in OSPAR Region III. Represents one of two areas representing shelf deeps; the other located in the Southern Trench in OSPAR Region II. Not currently understood for shelf deeps. The MPA area represents a functionally significant example of shelf deeps. There is at least on example of shelf deeps in each of the OSPAR Regions in which it has been recorded. Not considered threatened and/or in decline.
White cluster anemone No information available. Represents the only known example of white cluster anemones in Scottish seas No information available. No information available. No information available.
Circalittoral sand and mud communities No information available.

Anticipated Benefits to Ecosystem Services

Table 9. Summary of Ecosystem Services Benefits arising from Designation of the Site as an MPA [14] [ SMI]
Services Relevance
to Site
Baseline Level Estimated Impacts of Designation Value Weighting Scale of Benefits Confidence
Lower Intermediate Upper
Fish for human consumption High. Support food web and contains nursery habitats. Stocks not at MSY, some vulnerable habitats Nil Low - Moderate. Protection of shellfish beds can contribute to maintenance and recovery of stocks - benefits are higher under stronger protection measures but ecosystem response is uncertain. High. Commercially valuable species supported. Nil - Moderate Moderate, uncertainty mainly in response of habitats to management measures.
Fish for non-human consumption Stocks reduced from potential maximum
Gas and climate regulation Low Uncertain Nil Minimal Moderate, social cost of carbon Low Low - Moderate
Natural hazard protection Minimal Low Nil Minimal Low Minimal High
Regulation of pollution Moderate, benthic communities regulate pollution Low, major water quality issues to be dealt with through WFD Nil Minimal Low, water quality in this area not affecting human welfare Minimal High
Non-use value of natural environment Moderate - High, variety of protected features, and contribution of the site to MPA network, have non-use value. Non-use value of the site may decline Nil Moderate - protection of features of site from decline, and/or allowing some recovery Moderate - range of features means strong contribution to halting decline of marine biodiversity Nil - Moderate Low - Moderate, extent of features, responses to management measures, and value to society all uncertain
Recreation Moderate - High, including 1 active dive site, angling and recreational boating routes Moderate - High, including tourism activities. Angling may be reduced by damage to features Nil Low - Moderate, Angling benefits and biodiversity encountered by divers and recreational boaters are protected from possible decline, and could recover under upper scenario. Designation could enhance tourism activity. Moderate, extensive activities, but substitutes are available. Nil - Moderate, enhancement of activities through improved angling and visitor experiences. Nil - Moderate, extent of change from management measures uncertain
Research and Education Moderate, site contains some examples of unusual marine features. Moderate, biological features used for research, but there are substitutes Nil Low, some aspects of research value are not at risk, some aspects protected from possible decline, and could increase. Low - Moderate Nil - Moderate Low - Moderate, extent to which research uses site in future uncertain
Total value of changes in ecosystem services Nil for lower scenario, Moderate for upper scenarios Nil - Moderate Low
