The workshop was conducted by Ulysses Seal, Chairman of the IUCN/SSC Captive Breeding Specialist Group (CBSG), and Ronald Tilson, Director of· Conservation, Minnesota Zoo, coordinated by the CBSG and led by Asian Wetland Bureau- Indonesia. The workshop was attended by 25 people, including White-Winged Wood Duck specialists from India, England and Thailand, PHPA officials and staff, and Indonesian and European students working at Way Kambas National Park. The sponsors of the workshop included The Wildfowl & Wetlands Trust, Jersey \Vildlife Preservation Trust, George Williamson & Co.

The workshop focused on the status of the White-winged Wood Duck in Sumatra but incorporated relevant information from researchers from Assam and Thailand, two areas where the species is still observed in the wild, and from White-winged Wood Duck captive-breeding specialists. Two main working groups were established to investigate Distribution and Status and Life History and VORTEX Analysis. Two smaller groups, one comprising workers with first-hand experience of the current situation at Way Kambas National Park and one which included PHP A staff, were
