List of Threatened and/or Declining Species & Habitats
The OSPAR Biological Diversity and Ecosystems Strategy sets out that the OSPAR Commission will assess which species and habitats need to be protected. This OSPAR List of Threatened and/or Declining Species and Habitats has been developed to fulfil this commitment. It is based upon nominations by Contracting Parties and observers to the Commission of species and habitats that they consider to be priorities for protection.
Introduction (Agreement 2008-6)
Introduction1 2
1. The OSPAR Biological Diversity and Ecosystems Strategy sets out that the OSPAR Commission will assess which species and habitats need to be protected. This work is to guide the setting of priorities by the OSPAR Commission for its activities in implementing Annex V to the Convention ("On the Protection and Conservation of the Ecosystems and Biological Diversity of the Maritime Area").
2. This OSPAR List of Threatened and/or Declining Species and Habitats has been developed to fulfil this commitment. It is based upon nominations by Contracting Parties and observers to the Commission of species and habitats that they consider to be priorities for protection. The evidence in support of those nominations has been collectively examined by the OSPAR Commission and its subordinate bodies on the basis of the relevant Texel/Faial criteria for the identification of species in need of protection (Reference number 2003-13). The data used has been reviewed by the International Council for the Exploration of the Sea (ICES), in order to give assurance that its quality is suitable for the purpose for which it has been used3. The information used has been compiled into a justification report, which is being published separately (Case reports for the OSPAR List of Threatened and/or Declining Species and Habitats (OSPAR publication 2008/358).
3. The purpose of the list is to guide the OSPAR Commission in setting priorities for its further work on the conservation and protection of marine biodiversity. The inclusion of a species or of a type of habitat on this list has no other significance.
4. Fish species affected by fishing in this list are marked with an asterisk (*). These species are subject to management by an international or national fisheries authority or body. The OSPAR Commission has no competence to adopt programmes or measures on questions relating to the management of fisheries. Where the OSPAR Commission considers that action is desirable in relation to such a question, it is to draw that question to the attention of the authority or international body competent for that question. The inclusion of species affected by fishing in this list must be read in this context.
5. In order to avoid duplication of work, other international agreements (in particular, EC Directives (including the Council Directive 92/43/EEC on the conservation of natural habitats and wild flora and fauna and the Council Directive 79/409/EEC on the conservation of birds) and measures under the Berne Convention, the Bonn Convention (including its regional agreements) and the Ramsar Convention, amongst other relevant instruments) should also be taken into account by Contracting Parties to the extent that they are bound by them or committed to them.
6. The OSPAR Biodiversity and Ecosystems Strategy makes clear that it may be necessary to consider separate populations of species for the purposes of the strategy on the same basis as whole species. This list therefore specifies certain populations of species where separate treatment is justified, because the different populations are subject to differing pressures. Where this is done, there is no implication that other populations of the same species may be threatened and/or declining.
7. The OSPAR Commission wishes to consider any information that could improve the basis for the judgements that have been made in drawing up this list.
8. This OSPAR List of Threatened and/or Declining Species and Habitats will be subject to further development. Species and habitats will be added to or removed from the list, in the light of changes to their conservation status and to the threats they face and in the light of the latest scientific assessments, according to the Texel/Faial criteria.
9. The footnotes form an integral part of the list.

1 Replaces agreement 2004-6. See OSPAR 08/24/1, §7.12
2 Corrections made by OSPAR 2014 to the naming of Gadus morhua stocks to align with the standard naming of the ICES cod divisions.
3 The assessments of that data by the OSPAR Commission and by ICES differ in respect of Polysticta stelleri, Puffinus assimilis baroli, Thunnus thynnus and Oceanic ridges with hydrothermal vents/fields. The justification for the OSPAR assessment of these species and habitats is set out in the justification report
4 The OSPAR Regions are:
I - the Arctic: the OSPAR maritime area north of latitude 62°N, but also including Iceland and the Færoes;
II - the Greater North Sea: the North Sea, the English Channel, the Skagerrak and the Kattegat to the limits of the OSPAR maritime area, bounded on the north by latitude 62°N, on the west by longitude 5°W and the east coast of Great Britain, and on the south by latitude 48°N;
III - the Celtic Seas: the area bounded by, on the east, longitude 5°W and the west coast of Great Britain and on the west by the 200 metre isobath (depth contour) to the west of 6°W along the west coasts of Scotland and Ireland;
IV - the Bay of Biscay/Golfe de Gascogne and Iberian coasts: the area south of latitude 48°N, east of 11°W and north of latitude 36°N (the southern boundary of the OSPAR maritime area);
V - the Wider Atlantic: the remainder of the OSPAR maritime area.
5 That is, the populations/stocks referred to in ICES advice as the North Sea, Eastern Channel and Skagerrak cod stock; Kattegat cod stock; Cod west of Scotland; Cod in the Irish Sea; Cod in the Celtic Sea. (The naming of the stocks was corrected by OSPAR 2014 to align with ICES cod divisions).
6 In accordance with the comments of ICES in its review, the varying states of the numerous different stocks have to be taken into account.
7 The main threat is the high rate of catch of juvenile fish of the species (SCRS Report, page 59).
