Reintroduction of the Arabian oryx<i>Oryx leucoryx</i>in Jordan: war and redemption
Bibliographic record
Abstract
Abstract Following the extinction of the Arabian oryxOryx leucoryxin the wild in 1972 Jordan began a reintroduction programme in 1978 with 11 founding animals. When the herd size reached 31 in 1983 most were released from captive breeding pens into the 342 km2Shaumari Nature Reserve, part of which (22 km2) was fenced the following year to protect the oryx and exclude livestock. The herd grew initially (between 1979 and 1986) at about 23% per year. In 1990, when the herd numbered 79, its management was preparing to release it into the wild outside the fenced reserve. However, Bedouin families fleeing the Gulf War in Kuwait and Iraq brought 1.6 million sheep, goats, camels, and donkeys into Jordan. These livestock so overgrazed potential oryx habitat throughout the arid rangelands that reintroduction was impossible. Overcrowding within Shaumari became apparent by 1995, when the population numbered 186. The herd's rate of increase began to decline as productivity and recruitment decreased and mortality increased. In 1997, to reduce overcrowding, the herd's management began dispersing them to other Middle Eastern countries and to another nature reserve in Jordan. By February 2006, 43 oryx remained at Shaumari. In 2005, however, the prospects improved when the United Nations Compensation Commission awarded Jordan the cost of environmental damages resulting from the 1990–1991 Gulf War. Part of this award is designated for renewal of the captive breeding and reintroduction programme.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
