Saving Laos Elephants: Innovative DNA Research from Dung

Laos faces a decline in its Asian elephant population. Once home to a large number of these elephants, the country now supports only 500 to 1,000, a steep drop from 20 years ago, according to WWF-Laos. Factors such as habitat loss, logging, hunting, and limited breeding have contributed to this decline.

To combat this issue, researchers utilize DNA analysis from elephant dung to monitor both captive and wild populations. This approach aims to preserve genetic diversity and create effective breeding strategies for conservation. The Elephant Conservation Center (ECC) in Sainyabuli province is central to these efforts. Wildlife biologist Anabel Lopez Perez highlights the importance of maintaining a healthy captive population as a safeguard against wild population collapse.

At the ECC laboratory, researchers identify individual elephants through DNA testing. This process aids in managing genetic diversity, preventing inbreeding, and producing healthy calves for future release into the wild. The center currently cares for 28 elephants in its 500-hectare sanctuary. Mae Khoun Nung, one of the elephants, receives specialized care for her well-being.

Maintaining the elephant population in Laos is challenging. The mortality rate indicates that 10 elephants die each year for every one or two births. Wild elephant numbers have shrunk about half since the early 1900s, leaving only 40,000 to 50,000 remaining globally. Researchers are now collecting DNA samples from the last wild elephant group in Nam Poui National Protected Area, consisting of 50 to 60 individuals. This analysis will help track movements and understand herd dynamics.

The ECC attempts to protect captive elephants, but breeding has seen limited success with only three calves since 2010. As for Mae Khoun Nung, at 45 years old, she prefers to feed alone rather than socialize with other elephants. With over a decade of experience, keeper Sounthone Phitsamone acknowledges the serious challenges ahead for Laos’s elephant population and expresses uncertainty about their future.
