About the CCAHD

CCAHD Foundation Mission statement

Working towards the long-term sustainability of Atlantic humpback dolphin (Sousa teuszii) populations and their habitats through research, awareness, capacity-building and action.

The CCAHD Foundation

The CCAHD Foundation acts as an umbrella organization that brings together international conservation management bodies, cetacean scientists from around the world, and organizations and individuals in the countries where the Critically Endangered Atlantic humpback dolphin is found. The CCAHD Foundation’s aim is to promote and support research and conservation actions throughout the species’ range, and provide robust conservation advice on the Atlantic humpback dolphin.



The Consortium for the Conservation of the Atlantic Humpback Dolphin (CCAHD) was initiated in response to growing concerns regarding the declining conservation status of the species over recent decades. The formation of the CCAHD in June 2020 was motivated by several events including:

  • The uplisting of the IUCN conservation status of the Atlantic humpback dolphin from Vulnerable to Critically Endangered in 20171;
  • A meeting of cetacean scientists at the World Marine Mammal Conference in Barcelona in December 2019, during which participants discussed how to reinvigorate and prioritize conservation efforts for Atlantic humpback dolphins2;
  • A desire to implement the conservation and management measures recommended for the species by the Convention on Migratory Species, the IUCN Cetacean Specialist Group and the International Whaling Commission.  Despite several clear warning signs of declining status little progress has been made for the species during the 21st Century, and concerted collaborative effort is required to address this 3,4,5,6.

Following a systematic prioritisation exercise in 2020, the CCAHD published this report on short-and medium-term priorities for Sousa teuszii conservation. The CCAHD is now working to raise funds and implement those priority activities.

Legal Status and documentation

The CCAHD’s legal form is a Foundation (‘Stichting’) under Dutch law, with its seat in Amsterdam,  the Netherlands (RSIN number 863607366).  The CCAHD Foundation is guided by a Management Board and a Supervisory Board which are both composed of international and Sousa teuszii range country members.  The Foundation is supported by a Secretariat, which is currently based in the Netherlands.

The CCAHD Foundation’s full Articles of Association (in both Dutch and English) can be found here.

The CCAHD Foundation’s 5-year Strategic Plan can be found here.

The CCAHD Foundation’s Financial Policy (in English) can be found here.

The CCAHD Foundation’s Due Diligence Policy with regards to receiving and disbursing payements can be found here.

The CCAHD financial statement for the last Calendar year (2023) can be found here.

The CCAHD is certified as equivalent to a US public charity through an equivalency determination issued by NGOsource.

The CCAHD Foundation is also formally recognised as a Public Benefit or Charitable organisation in the Netherlands (ANBI status).


Partners include over 90 individuals and organisations from 15 of the 19 Sousa teuszii range countries as well as others with interest and experience in protecting Endangered cetaceans. A critical part of the CCAHD’s work is to support local scientists and conservation NGOs in Atlantic humpback dolphin range countries, liaise with range country governments to improve national species status, and increase within-country general awareness of the species. Achieving those goals relies on a network of local partners and national contact points in all of the confirmed and potential range countries.

The current list of CCAHD partners can be found here, and more insight into focal points and the status of knowledge about Atlantic humpback dolphins can be found by clicking on any of the range countries on our interactive map. The CCAHD welcomes contact from any local biologists, NGOs or interested individuals to further expand this network and maximize opportunities for conservation and collaboration.
