The return of the Arabian oryx Oryx leucoryx to Oman symbolized the success of a new approach to species conservation and established reintroduction as a conservation tool. Ten years after the species had been exterminated in the wild by poaching, the first 10 founder oryx, descendants of the ′World Herd′, were reintroduced to the desert in central Oman in January 1982. A second release followed in 1984 and the population grew slowly through a 3-year drought that was broken by rain in June 1986. Further years of good rainfall and more founders meant that by April 1990 there were over 100 oryx in the wild, independent of supplementary feed and water, and using a range of over 11,000 sq km. At that time a new monitoring programme was implemented that allowed the transition from individual- to population-based monitoring and management. The population continued to grow and by October 1995 numbered approximately 280 in the wild (of which 22 were surviving founders) and used over 16,000 sq km of the Arabian Oryx Sanctuary. However, in February 1996 poaching resumed and oryx were captured for sale as live animals outside the country. Despite the poaching the population continued to increase and by October 1996 was estimated to be just over 400. However, poaching intensified and continued through late 1996 and 1997. By September 1998 it had reduced the wild population to an estimated 138 animals, of which just 28 were females. The wild population was no longer considered viable and action was taken to rescue some of the remaining animals from the wild to form a captive herd.

Elephants Elephas maximus have declined in range and number in the wild in Sri Lanka, from c. 12,000 at the turn of the nineteenth century to c. 4000 today. While in the distant past the decline in elephant numbers was due largely to indiscriminate killing by sportsmen and trophy hunters, today elephants are being killed primarily because they interfere with agriculture. Human-elephant conflicts have increased substantially in the recent past and ivory poaching has become a byproduct of such conflicts. Elephant tusks have been used traditionally in the ivory-carving industry in Sri Lanka since the time of the ancient kings. Until the turn of the century, very little ivory was imported from Africa because there was a plentiful supply of tuskers locally available. Sri Lankan ivory carvers started to use African ivory in 1910. Today ivory and fake-ivory products are sold openly to tourists in some 86 shops in the island. Before the listing of the African elephant in Appendix I of the Convention on International Trade in Endangered Species (CITES), the value of raw ivory in Sri Lanka used to be $US228–285 per kg. After the listing, the price fell to $US72 per kg, reflecting a drastic drop in the demand for ivory from tourists. Many ivory carvers have switched to other jobs or are using substitutes (such as bone and horn) to produce fake-ivory carvings. Only about 7.5 per cent of bulls in Sri Lanka are tuskers and they are under poaching pressure outside protected areas. Given the rarity of tuskers in Sri Lanka, promotion of trade in ivory products, even locally, may pose a serious threat to their long-term survival in the wild.
