Baima Snow Mountain
The Baima Snow Mountain is a significant area for biodiversity conservation and a popular destination for ecological tourism. Its pristine natural environment offers a haven for researchers and nature enthusiasts seeking to explore high-altitude ecosystems, diverse wildlife, and breathtaking landscapes.
The Baima Snow Mountain National Nature Reserve is located in the northwestern part of Yunnan Province, within Deqin and Weixi Counties in Diqing Tibetan Autonomous Prefecture. Also known as the Baima Snow Mountain National Nature Reserve, it is covering an area of 190,144 hectares. It was established in 1983 with approval from the Yunnan Provincial Government and upgraded to a national-level nature reserve in 1988. The reserve is one of the best-preserved cold temperate primal forests in China and is the highest-altitude and largest natural reserve in Yunnan Province.
The area’s topography is highly complex, with significant variations compared to surrounding regions. The reserve’s terrain is higher in the north and lower in the south, lying at the transition zone between the Tibetan Plateau and the Yunnan-Guizhou Plateau. This unique location results in a rich and diverse natural environment, with distinct ecological transition zones.
The Baima Snow Mountain is home to abundant biological resources and is known for its remarkable natural landscapes, including high-altitude coniferous forests and vertical vegetation zones. The reserve is best known as the largest national nature reserve for the Yunnan Golden Monkey (Rhinopithecus bieti) in China. The main focus of conservation here is the high-altitude needleleaf forests, mountain vegetation, and the endangered Yunnan Golden Monkey.
On November 30, 2023, the National Forestry and Grassland Administration included the Baima mountain area in Diqing, Yunnan as a key habitat for the Yunnan Golden Monkey in the First List of Important Terrestrial Wildlife Habitats in China.

Plant Resources
Baima Snow Mountain National Nature Reserve belongs to the cool-temperate forest ecosystem, making it one of the most complete and primitive high-altitude coniferous forest regions in China’s low-latitude, high-elevation areas. According to the classification of China’s vegetation regions, it falls under the China–Eastern Himalayas forest plant subregion, within the Hengduan Mountains area, which is one of the most plant-diverse high-altitude regions in the world.
The reserve has identified 1,747 species of seed plants from 142 families and 587 genera, including subspecies, varieties, and forms. These include:
- Gymnosperms: 6 families, 14 genera, and 29 species.
- Angiosperms: 136 families, 573 genera, and 1,718 species.
- The reserve is home to 24 species of nationally protected rare and endangered plants, including:
- 4 species under first-class protection,
- 9 species under second-class protection, and
- 11 species under third-class protection.
In addition, there are 6 provincially protected plant species, of which 2 are under second-class protection and 4 under third-class protection.
The plant flora in the reserve is extremely diverse, encompassing nearly all the woody genera found in temperate regions of the world, such as fir, spruce, pine, maple, birch, oak, and rhododendron. The fir genus is particularly noteworthy, with 6 species (including varieties) of Abies, such as long-needle fir, sharp-tip fir, Cangshan fir, Sichuan-Yunnan fir, Yunnan yellow-fruit fir, and Zhongdian fir, all found in the same area—making it a rare concentration of species.
The rhododendron genus in the reserve is also notable, with 47 species identified, of which 36 species are endemic to the Hengduan Mountains, and 15 species have their type locality in the reserve or its vicinity.
In total, the reserve is home to 30 species of nationally and provincially protected plants, belonging to 20 families. These include:
- 1 species of ferns from 1 family,
- 3 families of gymnosperms with 6 species,
- and a variety of angiosperms with numerous species under protection.
This rich plant diversity is a key feature of the reserve, contributing to its exceptional ecological value.
Animal Resources
According to China’s zoogeographical classification, the reserve’s animals belong to the Palaearctic realm, specifically the Southwest China subregion and the Three Rivers Gorge area (Hengduan Mountains subregion).
Mammals The reserve is home to 100 species of mammals from 9 orders, 23 families, and 70 genera, accounting for 16.8% of China’s total mammal species and 33.3% of those found in Yunnan Province. Some of the notable species include the Yunnan golden monkey, snow leopard, leopard, clouded leopard, bear macaque, rhesus macaque, pangolin, black bear, brown bear, red panda, stone marten, otter, lynx, Himalayan musk deer, sambar deer, wild goat, mountain shrew, white-tailed shrew, web-footed shrew, and Burmese tree shrew.
Out of the 100 mammal species recorded in the reserve, 43 species are endemic to the area and its neighboring regions, representing 43.0% of the total species count. These include:
- 23 species endemic to the Hengduan Mountains,
- 8 species endemic to the Hengduan and Eastern Himalayas,
- 12 species endemic to the Hengduan Mountains and Tibetan Plateau.
The reserve also hosts numerous unique genera and even some unique families (or subfamilies), such as:
- Black shrew genus,
- Toothless shrew genus,
- Web-footed shrew genus,
- Long-nosed mole genus,
- Stenodactylus mole genus,
- White-tailed mole genus,
- Nasal monkey genus,
- Red panda genus,
- Spotted civet genus,
- Snow leopard genus,
- Cervus genus,
- Wild goat genus,
- White-throated rock squirrel genus,
- Rechethric squirrel genus,
- Forest jumping mouse genus,
as well as families like Mustelidae, Talpidae, Sciuridae, and Cricetidae.
The rich mammalian diversity in the reserve underlines its ecological importance and its role as a crucial habitat for both endemic species and globally significant wildlife.
Conservation Targets
The primary conservation targets of Baima Mountain National Nature Reserve are the high-altitude coniferous forests, the vertical vegetation zones of the mountainous landscape, and the Yunnan golden monkey (Rhinopithecus bieti). The Yunnan golden monkey is an endemic and first-class protected species in China, often referred to as a national treasure alongside the giant panda.
The Baima Mountain Nature Reserve is currently the largest national nature reserve for the Yunnan golden monkey in China. As the ecological environment continues to improve and conservation efforts are successfully implemented, the population of the Yunnan golden monkey in the reserve has steadily increased. From around 1,000 individuals in 2000, the population has grown to approximately 1,500 individuals, representing about 70% of the global population of this rare species.
