The Yangtze giant softshell turtle Rafetus swinhoei is the rarest turtle species, with just two individuals known to be surviving, one male in a zoo in China and one individual recently identified as a female in the wild in Viet Nam. As the species is on the brink of extinction, it is an urgent priority to search for additional individuals in the wild, and for areas where it may still be present. Here, we analysed areas where the species may still occur, identified through interview surveys in Viet Nam. In addition, we introduced a novel system for evaluating the potential for occurrence of this rare and elusive freshwater turtle, using a conservation priority index. This index was based on three recorded variables: (1) probability of the species' presence based on interviews with local fishers, (2) degree of habitat alteration, and (3) fishing intensity, with the latter two based on experts’ evaluation of the sites where the species could potentially be present. There were at least 13 independent, reliable sightings in the 2010s, seven of which were in 2018–2019, indicating that R. swinhoei potentially persists in the wild. Although the species was confirmed at only one site, there are at least three more sites where it is likely to be present, and 13 sites of conservation interest. We provide a description of all sites where the species is potentially present, and a summary of relevant interviews. The Da River system has the highest number of recent sightings. We recommend that a research and conservation project be initiated urgently, and outline how such a project could be implemented.

Based on several sources of information an overview has been given on the development, present situation and problems of conservation of animal genetic resources in Europe.

Presently, 1 029 breeds of cattle, sheep, goats, pigs, horses and asses are registered by the EAAP-Animal Genetic Data Bank, Hanover. 42.8 % of the breeds are classified as being ‘at risk’. More than 360 conservation programmes are underway, which, however, in many cases seem to be operated independently of the status of endangerment and of similar breeds in other countries.

The primary objectives of conservation in Europe, i.e. ‘conservation for potential use, later’ and ‘conservation for cultural reasons’, are different from the objective ‘conservation for sustainable use, now’, which is primarily expressed for developing countries. Different objectives call for different answers to questions, such as: are breeds appropriate units of genetic diversity, how should endangerment be defined, what should be conserved and is incrossing and selection compatible with conservation?

In view of the large number of breeds ‘at risk’ and of similar breeds existing in different countries as well as the high costs of conservation it is concluded that characterisation of breeds for genetic uniqueness is presently the most urgent task in conservation. This requires effective co-operation across national borders in Europe.
