Reintroducing antelopes into arid areas: lessons learnt from the oryx in Saudi Arabia

Abstract

We focus on constraints faced by antelopes reintroductions in arid environments, and propose keys to enhance their success, using the oryx project in Saudi Arabia as example: (1) Monitoring and management of reintroduced populations appear more important than the number of released animals; (2) Because of the low accuracy of population size estimators, we recommend to implement a continuous monitoring and to use several estimators to assess the reintroduced population size; (3) Reintroduction schedule should take into account the unpredictability of food resources in arid environments; (4) The re-establishment of desert antelopes depends as a priority on the enforcement of regulations to avoid poaching.
