Release captive-bred individuals to re-establish or boost populations in native range
A study in 1990–2007 in a desert reserve in west-central Saudi Arabia (Wronski et al. 2011) found that released captive-bred female Arabian oryx Oryx leucoryx survived more than 10 years and successfully reproduced, regardless of prior breeding experience. Released captive-bred female oryx lived 11-12 years in the wild. Average birth rates were similar for ’experienced’ females that had given birth prior to release (0.69 calves/year) and ‘inexperienced’ females that had not (0.74 calves/year). Between 1990 and 1994, a total of 76 captive-bred oryx were released, of which 36 were females aged 0.5-8.9 years (numbers of experienced/inexperienced mothers not specified). Animals were identified by collars, ear-tags or ear notches. Individuals were located at least once every two weeks until 2007.
