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. |
