Ailao Mountains
Mountains Mountain range in Yunnan with subtropical forests
The Ailao Mountains in southern Yunnan contain subtropical forests, tea terraces and Yi and Hani villages; trekking routes, nature reserves and local tea roads attract outdoor travellers.
The Ailao Mountains (Ailao Shan) are a north-south trending mountain range in Yunnan province, China, forming part of the highland backbone of central Yunnan. The range is notable for its montane forests and ecological diversity.
Slopes are covered by subtropical and temperate montane forest types, with cloud forests at higher elevations and a range of endemic flora and fauna. The area is used for scientific research and conservation and includes forested reserves and walking routes in places.
The mountains have long formed a natural ecological boundary within Yunnan and have been the focus of regional conservation efforts in the 20th and 21st centuries. Traditional local communities have used the slopes for agriculture and forest products.
Ailao Shan runs through central-southern Yunnan province; the range lies inland from the Red River and Mekong valleys and is part of Yunnan’s highland terrain. It is southwest of Kunming within the province.
- Biodiversity: Home to montane forest ecosystems with significant plant and animal biodiversity characteristic of central Yunnan highlands.
