Proposed protected features | |||||
Biodiversity Features Burrowed mud -tall seapen. Geodiversity Features Quaternary of Scotland - sub-glacial tunnel valley. Site Description The Central Fladen (core) proposed MPA site is a smaller offshore site compared to the Central Fladen proposed MPA within the Fladen Grounds to the east of the Orkney Islands. The site represents a new search location from the Fladen Grounds Broad Search Area. Potential Alternative Designations JNCC have identified science-based alternatives to the Central Fladen site as representative of the burrowed mud biodiversity feature within the MPA proposal. JNCC recommend that the southern (core) part of Central Fladen is designated as it represents the tall seapen, a different component of burrowed mud, although the rest of Central Fladen, Western Fladen or South-east Fladen could be designated to represent other burrowed mud components. |

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) | [ CFL(core)] | ||
---|---|---|---|
According to VMS-based estimates and ICES rectangle landings statistics, Nephrops trawls, whitefish trawls and seines, and pelagic trawls (over-15m) and whitefish trawls, nephrops trawls and other gears (pelagic trawls, other seines, and lines) (under-15m vessels) operate within the CFL (Core) proposed MPA. The value of catches from the CFL (Core) area was £217,000 (over-15m vessels) and £11,000 (under-15m vessels, indicated from ICES rectangle landings data) (annual average for 2007-2011, 2012 prices). Landings from the over-15m fleet are made predominantly into Fraserburgh (55% by value) and Peterhead (33%), and a smaller amount to Ijmuiden, The Netherlands (8%). For the over-15m fleet, nephrops trawlers operate in particular across the proposed MPA. Information submitted by Copeche indicated that French vessels operate in the CFL proposed MPA, but no information was provided on numbers of vessels or value of catches. Foreign VMS ping data indicate that 25 non- UK vessels were active in the CFL (core) area in 2012: 11 from Denmark; 5 from the Netherlands; 5 from Norway, 2 from Germany, 1 from France and 1 from Sweden. The Swedish, Dutch and German vessels fish with pelagic gear (pelagic trawls and purse seines) and therefore would not be affected by proposed management measures. However, most of the Danish and French vessels fish with mobile bottom gear (beam trawls, bottom trawls) and therefore would be impacted by the management measures assessed under the intermediate and upper scenarios. No information on gear types used by the Norwegian vessels was available. Provisional ScotMap data do not indicate any under-15m vessel activity in the CFL (core) 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. 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. 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. |

* Due to data confidentiality, the value of catches from some of the affected gear types has been summed together with other gear types that are not expected to be impacted by management measures. The cost impact on 'Other gears' is therefore an overestimate of the actual expected impact from the proposed management measures. Total costs = Sum of one-off costs and recurring costs for the site summed over the 20 year period. Average annual costs = Total costs divided by the total number of years under analysis ( i.e. 20). Present value of total costs = Total costs discounted to their current value, using a discount rate of 3.5%. Total change in GVA (2014-2033) = The change in direct GVA in the sector for the site summed over the 20 year period. Average annual change to GVA = Total change in direct GVA in the sector for the site divided by the total number of years under analysis ( i.e. 20). Present value of total change in GVA (2014-2033) = Total change in direct GVA in the sector for the site discounted to current value, using a discount rate of 3.5%. Direct and Indirect reduction in Employment = The average (mean) reduction in direct employment in the sector plus the indirect reduction in employment on the sector's suppliers. |

Two pipelines (PL6N and PL7N) overlap with feature extents for tall seapens under the upper scenario only within the CFL(core) proposed MPA boundary. Four licence blocks were awarded during the 27 th licensing round, all of which overlap with feature extents for tall seapens under all scenarios. None of the awarded blocks are wholly within the MPA proposal boundary. There are no significant discoveries within the awarded blocks. |
