ORYX VOL 32 NO 3 JULY 1998 Ten years of Arabian oryx conservation breeding in Saudi Arabia - achievements and regional perspectives Stephane Ostrowski, Eric Bedin, Daniel M. Lenain and Abdulaziz H. Abuzinada The National Commission for Wildlife Conservation and Development was established in 1986 to oversee all wildlife conservation programmes in Saudi Arabia. The Arabian oryx Oryx leucoryx is one of the flagship species of the Saudi Arabian reintroduction policy. It has been captive-bred since 1986 at the National Wildlife Research Center near Taif. With the creation of a network of protected areas in the former distribution range of the species, attention has shifted to the release of captive-bred oryx into Mahazat as-Sayd and 'Uruq Bani Ma'arid reserves. Similar programmes carried out in other countries of the Arabian Peninsula underline the need for regional co-operation and pan-Arabic public awareness programmes, in addition to captive-breeding and reintroduction projects. Introduction appears to be on the way to becoming another conservation success story.
