Staff members check the faeces of Przewalski's horses at the Helan Mountain Nature Reserve in northwest China's Ningxia Hui Autonomous Region, April 17, 2025. The Przewalski's horse is listed as endangered by the International Union for Conservation of Nature Red List of Threatened Species and is under first-class national protection.

Once extinct in China due to excessive poaching and environmental degradation, the Przewalski's horses were reintroduced to the country from Britain, Germany and the United States starting in the mid-1980s, and were raised in northwest China's Xinjiang Uygur Autonomous Region and Gansu Province.

Since 2024, a total of 18 Przewalski's horses in three batches from Xinjiang have been released into the Helan Mountain Nature Reserve in Ningxia, as a way to protect the endangered species. On April 13 this year, a Przewalski's horse gave birth to a foal, marking the first case of breeding after the reintroduction of the Przewalski's horse in the nature reserve. (Xinhua/Yang Zhisen)
