The CMS Secretariat is the Convention's coordinating body. Its functions are set out in Article IX of the Convention. They include
- Organize and service meetings of the Conference of the Parties (COP), the Scientific Council (ScC) and the Standing Committee (StC),
- promote and support the development of Agreements,
- stimulate and supervise research and conservation projects,
- promote the exchange of information between the Parties and
- liaise with international governmental and non-governmental organizations.
The CMS Secretariat is provided and administered by the United Nations Environment Programme (UNEP).
Since its establishment the Secretariat has been located in Bonn, Germany. After having been co-located with the Federal Agency for Nature Conservation (BfN), the Secretariat relocated to the United Nations Campus in Bonn in 1998. The premises are shared by a number of UN Agencies, such as: UN Volunteers (UNV), the Secretariat of the Framework Convention on Climate Change (UNFCCC) and the Secretariat of the Convention to Combat Desertification (UNCCD).
The Secretariat has staff in three duty stations outside of Bonn: in Abu Dhabi, United Arab Emirates, in Bangkok, Thailand, and in Washington DC, USA.
The CMS Office - Abu Dhabi is the CMS Secretariat’s largest out-posted office. It is hosted by and co-located with the Environment Agency - Abu Dhabi (EAD), thanks to a generous voluntary contribution made by EAD on behalf of the Government of the United Arab Emirates. The office includes the Coordinating Unit of the Memorandum of Understanding on the Conservation of Migratory Birds of Prey in Africa and Eurasia (Raptors MOU), and the Secretariat of the Memorandum of Understanding on the Conservation and Management of Dugongs and their Habitats throughout Their Range (Dugong MOU). The office aims to address common threats to migratory species of regional interest, such as marine mammals and marine turtles in relation to by-catch, while promoting CMS and its agreements in the West Asian and north-west Indian Ocean regions.
Based in Bangkok, Thailand, Mr. Douglas Hykle, former Deputy Executive Secretary of the Convention on Migratory Species, is the Co-ordinator of the IOSEA Marine Turtle MOU and Senior Advisor to CMS. The latter designation reflects the fact that a portion of his time is spent advising on broader CMS issues, apart from marine turtles, of concern to the Asia region.
These have included implementation of the Siberian Crane MOU, which he helped to develop in the early 1990s, as well as its associated site network and the UNEP/GEF wetlands project. He was also involved in the establishment of the CMS office in Abu Dhabi and the development of the Dugong MOU.
More recently, he has been involved in the drafting of a new Strategic Plan for the East Asia - Australasia Flyway Partnership, a cooperative initiative that brings together diverse partners from Government, NGOs and the private sector with a common interest in conserving migratory birds.
