Przewalski’s horse reintroduction in China surpassed 900 individuals, one-third of the global population, marking 40 years since the Wild Horse Return Program began restoring the world’s only remaining wild horse species from extinction.
The milestone follows decades of conservation work transforming the “living fossil,” with a 60-million-year evolutionary history, from zoo specimens into wild herds galloping across the steppes and deserts of northwestern China. The Przewalski’s horse reintroduction program launched in 1985, following the species’ declaration as extinct in the wild in the 1970s due to poaching, habitat loss, and ecological degradation, which eliminated populations from their native range.
Przewalski’s horse survival depended on just 12 wild individuals captured by European explorers in the late 19th and early 20th centuries. These founders created a severe genetic bottleneck, leaving captive zoo populations vulnerable to inbreeding and low genetic diversity. In 1978, the Foundation for the Preservation and Protection of the Przewalski Horse, based in the Netherlands, issued a call to reintroduce the species to its native habitat.
China responded by establishing breeding bases in Xinjiang Uygur Autonomous Region and Gansu Province. The Xinjiang Wild Horse Breeding and Research Center, Asia’s largest facility, has bred more than 800 horses and released 146 into the wild. The center received 18 founder animals from Germany, the United States, and other countries in the late 1980s, initiating a phased approach aimed at rebuilding wild populations.
The Dunhuang West Lake National Nature Reserve in Gansu Province became a critical rewilding site. Zhang Qiangwei, director of the Gansu Endangered Animal Protection Center in Wuwei city, reported that 56 trained horses were released into the reserve between 2010 and 2025. The area’s ecological conditions, including unfrozen springs and snow-free grasslands, allowed animals to adapt successfully.

The center currently cares for 45 individuals, with one-quarter being sub-adults. Around six foals are expected this year. The center’s goal is to build a healthy population with stable generational succession. The reserve’s population had surpassed 200, forming 28 herds demonstrating successful transition from captive breeding to self-sustaining wild populations.
The Przewalski’s horse reintroduction in China reached a technical peak in 2025 with the country’s largest long-distance relocation operation. Led by Professor Hu Defu of Beijing Forestry University, the mission transported 28 horses over 1,030 kilometers from the Wuwei center to the Dunhuang reserve using a pioneering loose-box transport method. Unlike traditional anesthetized crating, which often results in casualties, the 2025 operation achieved zero fatalities.
The Kalamaili Mountain Nature Reserve in Xinjiang represents another successful reintroduction site. By the end of 2024, the reserve had released 18 batches totaling 146 horses, which were organized into 27 wild herds. The first surviving wild-born foal arrived in spring 2003, signaling the species could sustain itself without human intervention.
Winter conditions presented formidable challenges. When temperatures plunged to minus 30°C, herds faced starvation. Conservation teams drove jeeps through blizzards, scattering alfalfa to guide horses to safety over three days. The reestablishment of natural social structures proved equally difficult, as Przewalski’s horses typically form harem groups, one male with several females, and bachelor bands. Restructuring these social units led to infanticide and the elimination of old or weak individuals, harsh yet natural laws of the wild.
Managing genetic diversity remains critical for long-term population viability. The Przewalski’s horse reintroduction in China addresses inbreeding risks through several strategies. Researchers transported stallions bred in China to Mongolia and wild horses from Xinjiang to Gansu to exchange genes and increase genetic diversity. A complete pedigree archive tracks all wild horses with DNA profiles, identifying over 100 individuals, enabling selection of distantly related individuals for breeding groups.
DNA testing projects at the molecular level enable precise breeding pairing using small amounts of hair and fecal samples. This genetic management prevents problems such as slow development, deformities, reduced adaptability, and diminished fertility that hinder species recovery efforts.
Infrastructure modernization supports population growth. The Gansu center built a 6.67-hectare breeding base, an 800-square-meter forage storage facility, automated watering systems, and high-definition monitoring networks.
The species’ cultural significance expanded beyond conservation. Przewalski’s horse inspired the creation of “Chengcheng,” the mascot for the 2026 Year of the Horse Spring Festival Gala, becoming a flagship symbol of ecological restoration. The stocky, dun-colored horses with distinctive large heads, thick necks, and black lower legs represent China’s commitment to biodiversity protection.
The Przewalski’s horse reintroduction in China has opened rewilding efforts across Xinjiang, Gansu, Inner Mongolia, and Ningxia with habitats steadily enlarging. Today, rewilded horses roam vast wilderness areas their ancestors inhabited for millennia before ecological degradation and human activity drove them to extinction. The Gansu center has bred, relocated, and released over 300 horses total, demonstrating the scalability of reintroduction techniques.
The Przewalski’s horse reintroduction in China is one of the world’s most successful large-mammal reintroduction programs, internationally recognized as a model for endangered species recovery. However, challenges persist despite remarkable progress. Expanding populations remain a long-term task, as wild populations are mainly found in China and Mongolia but are relatively small. Space restrictions slow population growth in some reserves. Disease management requires ongoing vigilance, including monitoring for tick-transmitted granulocytic anaplasmosis and Streptococcus equi infections affecting the respiratory system.

Przewalski’s horse derives its name from Russian explorer Nikolai Przhevalsky (also spelled Przewalski or Prejevalsky), who brought the species to Western scientific attention in the 19th century after discovering specimens in the Dzungarian Basin.
The transformation from 11 reintroduced horses in 1985 to more than 900 by 2025 demonstrates that conservation can reverse extinction trajectories when sustained over decades through coordinated effort, scientific management, and resource investment supporting species recovery across their native range.
