CMS

The Convention on the Conservation of Migratory Species of Wild Animals (CMS) is an environmental treaty of the United Nations.

It’s a framework convention with legally binding treaties (Agreements) and Memorandums of Understanding (MoU) for species that cross national boundaries. CMS serves as an intergovernmental platform to bring Range States (nations with jurisdiction over any part of the species range) together to agree internationally coordinated conservation measures throughout the migratory ranges of species listed under CMS.

CMS Sharks MOU

The CMS Sharks MOU is a global agreement under the auspices of CMS, which aims to maintain and achieve a favourable conservation status for migratory sharks and rays. The MoU is non-binding. A Conservation Plan outlines key objectives, and in pursuing activities described, Signatories should endeavour to cooperate through Regional Fisheries Management Organisations (RFMOs) and other treaties.

The Shark Trust is a Cooperating Partner to the CMS Sharks MOU, which means we support the Signatories, Range States, and the Secretariat in meeting the objectives of the Sharks MOU.


SPECIES LISTINGS:

Species can be listed on two Appendices:

Appendix I – includes species that are considered endangered throughout all or a significant portion of their range. Parties that are a Range State to Appendix I listed species should endeavour to strictly protect them.

Appendix II – includes migratory species that have an unfavourable conservation status and require international agreements (e.g. MOUs, Action Plans, Species Initiatives). Parties are committed to work towards conservation and management of Appendix II listed species.

  • Smooth Hammerhead Sphyrna zygaena (2020)


All the above species are also listed on the CMS Sharks MOU, with the exception of the Blue Shark, Tope and Smooth Hammerhead.

CONCERTED ACTIONS

CMS Sharks MOU listings can be accompanied by a Concerted Actions document outlining priority conservation measures, projects, or institutional arrangements to improve the conservation status of selected species/groups of species. They either a) involve measures that are the collective responsibility of Parties acting in concert; or b) are designed to support the conclusion of an instrument under Article IV of the Convention and enable conservation measures to be progressed in the meantime, or represent an alternative to such an instrument.

The Concerted Action for Angelsharks provides a framework of activities which reflect those outlined in the Eastern Atlantic and Mediterranean Angel Shark Conservation Strategy.

IMPLEMENTATION

CMS Parties are obligated to strictly protect Appendix I listed species and work internationally toward conservation of those listed on Appendix II. Despite this, most CMS Parties continue to fall short in this regard. In addition, there has been inadequate regional progress through fisheries bodies for those sharks and rays listed on Appendix II, leaving many of the listed species with insufficient protection.

Together with our partners, we continue to urge Parties to focus on effective implementation of listings, including existing obligations for the many sharks and rays listed. Overfishing must be directly addressed to secure a future for these vulnerable species.
