Reintroduction of Asian elephants to restore forest ecology in Thailand

Summary

Thailand's captive and wild elephant population has fallen from roughly 100,000 in 1957 to about 6,000 today, and in January 1997 Queen Sirikit launched a reintroduction program by releasing three adult female elephants into the Doi Phamuang Wildlife Sanctuary, chosen for its existing wild elephants, food supply, natural barriers and lack of human conflict. Elephants entering the Elephant Reintroduction Foundation's program, donated or purchased from logging or tourism work and each carrying an identification microchip, are health-screened, quarantined for 30 to 60 days, then soft-released while dragging a free-ended chain so they can still be recovered if needed, with six months of close observation of health, behaviour and group formation before a fully independent hard release follows over the next few months to two years. By the time of writing, 108 elephants had been released across three protected areas in central, northern and northeastern Thailand, with GPS and satellite collars on matriarchs tracking group movements and weekly mahout-ranger patrols checking on the herds. Most released elephants have grown wary of people, and 19 calves had been born from natural mating among them by May 2017, evidence of successful social integration and breeding. Crop raiding and conflict between elephant groups sharing limited forest have been recurring problems, and some aggressive bulls have had to be confined rather than freely released. The project rates itself highly successful, crediting strong royal and public backing along with the elephants' visible role in forest restoration.
