The White-shouldered Ibis, Pseudibis davisoni, is listed as ‘CRITICALLY ENDANGERED’ on the IUCN Red List of Threatened SpeciesTM. Having suffered dramatic declines over much of its former range during the course of the 20th century, the White-shouldered Ibis is now confined to just a few sites in Vietnam, extreme southern Lao People’s Democratic Republic, Kalimantan (Indonesia) and, principally, northern Cambodia, where some 300 birds survive.

Much of the historical decline of the White-shouldered Ibis was due to habitat loss through logging of lowland forest, drainage of wetlands for agriculture, livestock grazing, grass harvesting, development and hunting. With most populations occurring close to human habitation, disturbance, hunting, logging and infrastructural projects are now putting the most pressure on this species.

As one of the most threatened waterbird species in Southeast Asia, concerted efforts are being made to conserve the White-shouldered Ibis, including various public education campaigns and ecotourism projects. Conservationists are hoping to bring the largest remaining populations under effective protection, a measure which is seen as integral to the recovery of this species.
