Saiga antelopes, among the most ancient living mammals, are set to be reintroduced to China 75 years after they went extinct in the region, thanks to a donation of 1,500 wild individuals from Kazakhstan.

The transfer, announced during a meeting between the countries’ presidents on June 17, is projected to begin in 2026. Its aim is to restore part of the antelope’s historic range, which stretched from Kazakhstan into northwest China until the 1950s.

The donation “is a significant conservation-driven move aimed at restoring the saiga population in China and promoting international collaboration on the conservation of transboundary species,” conservation biologist Zhigang Jiang, a professor at the Chinese Academy of Sciences, told Mongabay by email. Jiang co-authored a 2017 study on the saiga antelope’s historic range and its prospects for reintroduction in China.

The saiga (Saiga tatarica), most easily recognized for its large otherworldly nose, lived alongside Ice Age megafauna like woolly mammoths and saber-toothed cats thousands of years ago. Until the 1800s, the species could be found as far as Eastern Europe, but its range has contracted ever since.

Disease and poaching pushed the antelope’s population to a historic low of fewer than 30,000 individuals in 2003, before it bounced back following a recovery effort led by the Kazakh Altyn Dala Conservation Initiative.

As of April, there are now an estimated 4.1 million individuals, with more than 98% concentrated in Kazakhstan’s Golden Steppe.

China has tried to reintroduce the saiga into the wild since the 1980s, but low numbers and a limited gene pool from its captive population have largely frustrated previous efforts. A safe translocation from other populations has been considered for decades as a possible but challenging fix.

“For the reintroduction to succeed, it’s crucial to identify habitats for saiga in China,” Jiang said. “Open steppe and semi-desert ecosystems, with low human disturbance and migratory space, will support large herds of saigas.”

Wild saigas were last recorded in China in the Junggar Basin of China’s northwestern Xinjiang Uyghur Autonomous Region, which borders Kazakhstan. But according to Jiang, other sites could also potentially host saiga herds, including areas bordering Xinjiang such as the Qaidam Basin of Qinghai province, northern Gansu, western Inner Mongolia and Ningxia.

“I am expecting the reintroduced saiga from Kazakhstan to return to its historical range in China,” Jiang added.
