What ARE Small Cetaceans?
Whales, dolphins and porpoises belong to the scientific order known by
the Latin term Cetacea. They are aquatic mammals and most of them are
marine, i.e. they live in the sea. Cetaceans spend their whole life in
Two main types of cetaceans exist today. Species of the suborder Mysticeti, or baleen whales, are characterised by having baleen plates for filtering food from the water, rather than teeth. They are relatively large and include, for example, the blue whale, the largest animal ever to have lived on earth. Most members of the suborder Odontoceti, or toothed whales, are considerably smaller and are accordingly called small cetaceans. They feed predominantly on fish and squid.

Are small cetaceans hunted in the Agreement Area?
Small cetaceans are no longer deliberately hunted in the Agreement area.
However, they are threatened in many other ways. See below for more on
Geographically the closest hunt of small cetaceans is the annual catch of pilot whales and other species on the Faeroe Islands. This area is not included in the ASCOBANS Agreement and therefore this practice falls outside of the treaty’s range of application. It is unclear whether populations occurring in the ASCOBANS Agreement Area are also affected by the hunt.
What threats exist for small cetaceans in the ASCOBANS area?
Most cetacean species are highly mobile, following their prey over long distances or migrating regularly between breeding or feeding ranges. In the ASCOBANS Area they encounter a variety of man-made threats, of which bycatch, the accidental entanglement in fishing gear, is considered the most serious. Every year, several thousand cetaceans drown because they become ensnared in fishing nets, preventing them from coming up to the surface to breathe.
Marine pollution is another serious threat that calls for an international, coordinated approach. Toxic substances like heavy metals and persistent organic compounds, most notably the PCBs, enter the food chain and accumulate in the body tissues of marine mammals, adversely affecting their health.
Commercial shipping, industrial activity (e.g. pile-driving and seismic explorations), explosions and navy sonar cause underwater noise. Such acoustic disturbance can lead to behavioural changes, physical injury and even death. Moreover, the expanding shipping fleets result in increasing numbers of ship strikes, collisions between the vessels and the cetaceans, which is of growing concern.
The extent and the effects of the threats faced by small cetaceans vary among areas and species. The combined effects of all human activities are unknown, but it is clear that cetaceans are under additional pressure from prey depletion, habitat degradation and climate change, which have a detrimental effect on whales, dolphins and porpoises.

What is ASCOBANS?
The acronym ASCOBANS stands for Agreement on the Conservation
of Small Cetaceans of
the Baltic, North East Atlantic, Irish
and North Seas.
ASCOBANS is an intergovernmental treaty that was concluded in 1991 as the Agreement on the Conservation of Small Cetaceans of the Baltic and North Seas under the auspices of the Convention on the Conservation of Migratory Species of Wild Animals (UNEP/CMS or Bonn Convention). The Agreement Area was extended westwards in early 2008.
ASCOBANS is open for accession by all Range States (i.e. any state that exercises jurisdiction over any part of the range of a species covered by the Agreement or whose flag vessels engage in operations adversely affecting small cetaceans in the Agreement Area) and regional economic integration organizations. Many, but not all countries in the Agreement Area have already become Parties to the Agreement and ASCOBANS continues to grow. The Parties share the common concern that continuously high bycatch rates, habitat deterioration and increasing anthropogenic disturbance are likely to threaten the existence of small cetaceans in the Baltic and North Seas, North East Atlantic and Irish Sea.
What does ASCOBANS do?
Since migrating cetaceans regularly cross national boundaries, their protection can only effectively be achieved by means of international cooperation. Thus, the aim of the Agreement is to promote close cooperation amongst Parties with a view to achieving and maintaining a favourable conservation status for small cetaceans in the ASCOBANS Area. A Conservation and Management Plan, which forms part of the Agreement, obliges Parties to engage in habitat conservation and management, surveys and research, pollution mitigation and public information. To achieve its aim, ASCOBANS also cooperates with Range States that have not (yet) acceded to the Agreement, with relevant intergovernmental organizations and non-governmental organizations.

How does ASCOBANS work?
Three main bodies promote the implementation of the Agreement:
The Meeting of Parties (MOP):
The Meeting of the Parties is the decision-making body of the Agreement. It meets every three years to assess progress and develop further steps in the implementation of ASCOBANS. Non-Party Range States and relevant regional, intergovernmental and non-governmental organizations can attain observer status to attend MOP meetings without having power to vote.
The Advisory Committee (AC):
The AC, which meets at least once a year, provides scientific and policy advice to the Parties and the Secretariat on the conservation and management of small cetaceans and on other matters related to the running of the Agreement. Each Party is entitled to appoint one member to the AC, who may be accompanied by advisors. As with the MOP, external observers may take part in AC meetings, while the nominated members are the only ones entitled to vote.
The ASCOBANS Secretariat acts as the coordinating body of the Agreement. It provides administrative support, gathers and disseminates relevant information and supports the Parties in the implementation of the Agreement. In addition, it prepares content for, organizes and services the meetings of the MOP and the AC. The Secretariat also plays an important role in awareness-raising. As with CMS and some of its other regional daughter agreements, the ASCOBANS Secretariat is administered by the United Nations Environment Programme and is based in Bonn, Germany.

Which countries participate in the Agreement?
ASCOBANS currently has ten Parties: Belgium, Denmark, Finland, France,
Germany, Lithuania, the Netherlands, Poland, Sweden and the United Kingdom.
In addition, there are seven non-Party Range States: Estonia, Ireland, Latvia, Norway, Portugal, Russian Federation and Spain. The European Union could also accede to the Agreement, as could any other country whose flag vessels engage in operations adversely affecting small cetaceans in the Agreement Area.

What can I do to help?
Cetacean conservation only works with public support and all of us can make a contribution to help save these charismatic animals. Click here for some suggestions for people of all ages and walks of life.
How do I find out about vacancies or internships in the Secretariat?
Any vacancies of the ASCOBANS Secretariat are posted, together with those of the other Secretariats of the CMS Family of Agreements, on the CMS website. CMS and ASCOBANS also run a joint internship programme, advertised on the same page) and interested university students are welcome to apply.
