Abstract: In order to collect accurate information on the status of the nearly
extinct Hainan black crested gibbon, I lead a comprehensive survey of the whole remaining
rain forest of the Bawangling National Nature Reserve. The survey was carried out
in October 2003 and was organised by the Kadoorie Farm & Botanic Garden (Hong
Kong). Numerous teams were especially trained in order to participate in this true
collaborative effort. We succeeded in carrying out a cout of the entire gibbon population.
Our finding that the gibbons still survive can be regarded as the "good news".
The "bad news" are that the population was determined to comprise only
13 gibbons. As a result of our survey, however, conservation efforts to save the
Hainan black crested gibbon appear to be increasing.
