Future of elephants living in captivity hangs in the balance

Scientists at the University of Sheffield and University of Turku are looking at ways to boost captive populations of Asian elephants without relying on taking them from the wild.

Almost a third of Asian elephants are in captivity in countries like India, Myanmar and Thailand, mainly being used in the timber industry to drag logs or for tourism.

Sustaining wild populations is the conservation priority but, with so many individuals in captivity, maintaining sustainable captive populations with high welfare standards is also important for the future of the species.

The sustainability of these elephant populations has always relied on the capture of their wild counterparts, but now they are a protected species their future is uncertain.

In a joint research study, the University of Sheffield and the University of Turku, in Finland, working alongside The Myanma Timber Enterprise (MTE), investigated how trends in elephant capture from the wild influenced birth, death and population growth in 3,500 working elephants over 54 years.

Using birth and death rates from years where wild-capture was reduced the scientists assessed the outlook for captive elephants and found that the population is vulnerable to decline.

The research, published in Proceedings of the Royal Society B, suggests that immediate population declines may be reduced if survival in juvenile elephants is improved.

This could involve improving welfare standards during the training period, as the elephants are separated from their mothers and trained for work around the age of four, which can be stressful for them, and identifying pregnant females earlier and improving their welfare so they can provide for and bond with their calf.
