Human Activity Summaries
Human activities that would be impacted by designation of the site as an MPA
Table 4a. Aquaculture (Finfish) | [ LFG] | ||
---|---|---|---|
There are three finfish farms within the boundary of the LFG proposed MPA, Ardcastle Bay, Furnace Quarry and Quarry Point. Furnace Quarry directly overlaps with the Burrowed Mud feature under all scenarios (lower, intermediate and upper). Ardcastle Bay and Quarry Point overlap with this feature under the upper scenario only. There are two additional finfish farms within 1km of the feature under all scenarios (Evanachan Marine Hatchery and Evanachan Salt Water). Furnace Quarry directly overlaps with Ocean Quahog feature under all scenarios. Ardcastle Bay and Quarry Point overlap with this feature under the intermediate and upper scenarios only. There are two additional finfish farms within 1km of the feature under all scenarios (Evanachan Marine Hatchery and Evanachan Salt Water). Furnace Quarry directly overlaps with the Sublittoral mud and mixed sediment feature under all scenarios. Ardcastle Bay and Quarry Point overlap with this feature under the intermediate and upper scenarios only. There are two additional finfish farms within 1km of the feature under all scenarios (Evanachan Marine Hatchery and Evanachan Salt Water). There is no public information on potential future development within the proposed MPA. In the absence of information on potential future developments, the assessment has focused on the costs associated with obtaining new CAR licences. A national assessment of the costs of obtaining planning permission for new developments is provided separately. |

There are two shellfish aquaculture sites within the boundary of the LFG proposed MPA, Loch Fyne and 'Site 1'. Both sites overlap with the Burrowed Mud feature under the high scenario only. Burrowed mud is present within 1km of the sites under all scenarios. Both sites directly overlap with the Ocean Quahog feature under the intermediate and upper scenarios. Ocean quahog is within 1km of the sites under all scenarios. Both sites overlap with the Sublittoral mud and mixed sediment communities feature under the high scenario only. This feature is also within 1km of the sites for the high scenario only. There is no public information on potential future development within the proposed MPA. In the absence of infomation on potential future developments, no site specific assessment has been possible.

Table 4c. Commercial Fisheries (assuming zero displacement of fishing activity) | [ LFG] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, Nephrops trawls, dredges, pelagic trawls and other gears (over-15m) and pots, nephrops trawls, hand fishing and other gears (under-15m vessels) operate within the LFG proposed MPA. The value of catches from the LFG area was £36,900 (over-15m vessels) and £56,100 (under-15m vessels, indicated from ICES rectangle landings data) (average for 2007-2011, 2012 prices). Landings from the over-15m vessels are made predominantly into Tarbet (95% by value). For the over-15m fleet, nephrops trawlers operated in particular in the southern and central and part of the proposed MPA across all the features in this area. Provisional ScotMap data indicate that the annual average earnings from the LFG proposed MPA was £78,200, with over 60% from Nephrops pots and 28% from Nephrops trawls. It is likely that the ICES rectangle estimate for the cost impact on <15m Nephrops trawls is an under-estimate; the value from ScotMap for the whole MPA area is £0.02 million (compared to £0.007 million from ICES rectangle data). The coverage for ScotMap interviews in the region was 63.8% (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 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 LFG 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 4d. Military | [ LFG] | ||
---|---|---|---|
One coastal military location (Loch Goil noise range) overlaps with the LFG proposed MPA boundary. The Loch Goil noise range overlaps with low or variable salinity habitats (all scenarios), sublittoral mud and mixed sediment communities (intermediate and upper scenarios), ocean quahog (intermediate and upper scenarios) and burrowed mud (upper scenario). Nine military practice areas (Minard (X5602), Fyne (X5603), Goil (X5604) and Tarbert (X5517); and five submarine exercise areas) overlap with the LFG proposed MPA. The military practice areas Minard (X5602), Fyne (X5603) and Goil (X5604) overlap with burrowed mud (all scenarios), ocean quahog (all scenarios) and sublittoral mud and mixed sediments (all scenarios). Minard (X5602) also overlaps with flame shell beds (all scenarios) and horse mussel beds (all scenarios), whilst Goil (X5604) overlaps with horse mussel beds (all scenarios) and low or variable salinity habitats (all scenarios). The military practice area Tarbert (X5517) overlaps with ocean quahog (intermediate and upper scenario), burrowed mud (upper scenario) and sublittoral mud and mixed sediment communities (upper scenario). The five submarine exercise areas overlap with the features of the LFG 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 4e. Ports and Harbours | [ LFG] | ||
---|---|---|---|
There are three ports/harbours (Furnace, Inverary and Portincaple) within the LFG proposed MPA boundary. Furnace overlaps with burrowed mud, ocean quahog aggregations and sublittoral mud and mixed sediment communities under all scenarios. Inverary overlaps with burrowed mud (upper scenario only), ocean quahog (intermediate and upper scenarios) and sublittoral mud and mixed sediment communities (upper scenario). Portincaple overlaps with burrowed mud, horse mussel beds, low or variable salinity habitats, ocean quahog aggregations and sublittoral mud and mixed sediment communities under all scenarios. There are five anchorages/mooring areas within the LFG proposed MPA boundary. Two anchorages/mooring areas overlap burrowed mud under the high scenario whilst two further anchorages/mooring areas overlap ocean quahog and sublittoral mud and mixed sediment communities under all scenarios. The remaining anchorage/mooring area overlaps ocean quahog and burrowed mud under the intermediate and upper scenarios only ( i.e. no overlap under lower scenario). Costs may be expected to relocate anchorages/mooring areas to less sensitive areas, although any associated costs are non-quantifiable. |

Table 4f. Recreational Boating | [ LFG] | ||
---|---|---|---|
There is one medium traffic cruising route within the LFG MPA proposal boundary that overlaps with features proposed for designation, although cruising routes are not expected to incur any management or assessment costs. Under the upper scenario there are 21 anchorages (and associated 100m buffer zones) within the MPA proposal boundary that overlap with proposed protected features. Overlaps with burrowed mud, low and variable salinity habitats, ocean quahog and sublittoral mud and mixed sediment communities have been identified. A further 21 Crown Estate mooring points are present within the proposed MPA under the upper scenario and ten larger mooring areas. A number of individual mooring points are located within these larger mooring areas within the proposed MPA, although it is expected that this may be an underestimate and additional moorings are found within the areas that are not represented by the data.The Crown Estate moorings show overlaps with ocean quahog, burrowed mud, sublittoral mud and mixed sediment communities and low and variable salinity habitats. Under the intermediate and lower scenarios, SNH have identified two recreational anchorages and three mooring areas owned by The Crown Estate that overlap with proposed protected features. Point records of low and variable salinity habitats and horse mussel beds occur between the two anchorages. The Crown Estate's mooring areas also overlap with multiple records of burrowed mud and sublittoral mud and mixed sediment communities, and one overlaps with five records of ocean quahog. |

Activity | Description |
Power Interconnectors | Three existing power interconnectors overlap with the LFG proposed MPA. All three power interconnectors overlap with ocean quahog (all scenarios) and sublittoral mud and mixed sediment communities (all scenarios). In addition the power interconnectors overlap with burrowed mud (upper scenario only) and occur within 1km of burrowed mud under all scenarios. No cost impacts are foreseen, as it is assumed that there will be no review of the existing consents. |
Water Sports - Dinghy Sailing | There is one dinghy sailing centre (The Lochgoilhead Centre) located within LFG proposed MPA. Water sports activities including dinghy sailing are not assessed as requiring any additional management measures. It is also considered that no additional benefit to dinghy sailing from management measures applied to other activities will occur. |

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 | Low - Moderate, protection of features of site from minor decline | 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 active dive sites, 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. | Low - Moderate, enhancement of activities through improved angling and visitor experiences. | Nil - Moderate, extent of change from management measures uncertain | |
Research and Education | Low | Low, small number of biological features have research value and there are substitutes | Nil | Low, protection of key characteristics of site from decline, improving future research opportunities | Low for individual features. Moderate for opportunity to understand response of wide range of features to management | Low | 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 | Low - Moderate | Low |
