Abstract: The Arabian Oryx (Oryx leucoryx) is listed as critically endangered by the International Union for the Conservation of Nature and a reintroduction effort currently is underway involving three release sites in the Negev desert of southern Israel. We describe a simulation model developed to project future population trends in view of uncertainties concerning establishment of migration corridors among release sites and post-reintroduction increases in natality rates. We first evaluate ability of the model to simulate observed trends in population growth following reintroductions of Arabian Oryx in Oman, and trends observed to date in the Israeli Negev. We then use the model to project future scenarios in the Israeli Negev under all combinations of three assumptions regarding establishment of migration corridors and two assumptions regarding post-reintroduction increases in natality rates.
