The region of Hengduan Mountains of Yunnan in China, is a world's biodiversity hot spot and place of origin and reservation for various species. In recent years, wild ancient tea trees of some 2700 years old, half wild-half cultivated ancient tea trees older than 1000 years and well preserved large ancient Pu'er tea plantations with tea trees of 100-1000 years old have been discovered in this area, making it one of the regions that practiced earliest use of tea resource and had significant influence on the tea culture of the world.

The nominated property is located on the Jingmai Mountain in the southwestern border area of Yunnan Province, with widely distributed tea plantations. The Mountain has a declining trend from the northwest to the southeast. In about 180 A.D., a branch of Blang, an ethnic minority group, discovered tea when migrating to the region of Jingmai, and tried to cultivate tea trees in the forest because of limited land and the climate and soil conditions favorable for tea trees. In the 3rd century, Blang people gradually mastered the tea cultivation techniques, and began to domesticate, cultivate tea trees and trade tea products, thus started the 1800 years’ history of tea cultivation, settlement and development in this area and passed on from generation to generation. According to historical records, the earliest recorded tea market in the nominated area came out in 1139 A.D., and the tea trade flourished in the Qing Dynasty.

In the nominated area, the highest elevation reaches 1662 meters (Nuogang Mountain) and the lowest 1100 meters (Nanlang Valley). Ancient tea plantations are mainly distributed in the mountain area of 1250-1550 meters above sea, and concentrates in three areas: Manggeng-Mengben ancient tea plantations, Jingmai Dapingzhang-Nuogang ancient tea plantations and Mangjing ancient tea plantations. In a total area of 1870 hectares, there are about 1.13 million ancient tea trees, of which the oldest tea tree has a history of 1400 years. Less than 10% of the tea trees are aged500-1000 years, about 30% are 300-499 years old, and the average age of the tea trees in the entire biocenosis is about 200 years. The nominated area is not only the largest and the best-preserved ancient tea plantation area of the region, but also the largest ancient cultivated arbor tea plantation of the world.

Ancient tea trees grow extensively in secondary growth tropical monsoon evergreen broad-leafed forests in South Asia. Such forests have the arbor layer at the top, the shrub layer in the middle and the vegetation layer at the bottom. Tall arbors such as toona ciliata and ficus microcarpa grow in the upper layer; the middle layer is dominated byancient tea trees and decorated with lauraceae, ericaceae and other plants; and the lower layer is covered by gramineae and herbs such as ferns, galenicals and wild vegetables. Compared with common terraced tea plantations, such a special multi-layered ecosystem helps ancient Pu’er tea plantations with well-preserved soil fertility and effectively reduced disease and pest. The special way of tea cultivation in forests was created by human through persistent study of the nature.

Over more than one thousand years, native people have built a close and friendly interaction with the ancient tea plantations based on discovery, cultivation and utilization of tea, thus forming a charming mountain settlement landscape and rich regional ethnic culture. The nominated property involves two administrative villages, namely Jingmai and Mangjing, with a total population of about 5,500 from more than 1500 households, respectively belonging to the Dai, Blang, Hani and Wa nationalities. In this region there are eight minority villages with distinctive characteristics generally built in area about 1500 meters above sea with sufficient sunlight, surrounded by forest, farmland, wild tea trees and wild animals.

Regional scope supporting the value of the nominated area is integral. The nominated areas of the ancient tea plantations are sufficiently large to exhibit the value content of the cultural landscape of tea industry. The nominated area includes 16,000 hectares of cultivated ancient tea plantations with about 1.13 million ancient tea trees. It is the largest one of the 14 major Pu'er ancient tea mountains, including all elements to exhibit the tea culture landscape. Besides, there are about 23,000 hectares of terrace tea plantations, about 34.5 million tea trees, approximately 69,000 hectares of symbiotic woodland in original state, eight villages, and four native ethnic groups of Blang, Dai, Hani and Wa.

Comparison with other similar properties There are 18 World Heritage properties related to agricultural landscape in the World Heritage List, including 6 of beverage plants, 2 related to coffee and 4 related to grape wine. At present, there is not a cultural landscape World Heritage focusing on tea cultivation and tea culture. Tea as one the three major beverages of the world is an important agricultural heritage with outstanding universal value.

The famous Assam tea plantation in India, tea plantations in Sri Lanka, Shizuoka tea plantation in Japan, etc. are mainly terrace tea landscapes with standardized modern cultivation. They are professionally managed by limited corporations with large scale. While the Ancient Tea Plantations of Jingmai Mountain are cultural landscapes formed by adaptation to the nature under extreme conditions. The local people discovered, domesticated and cultivated tea to form a traditional way of ancient tea cultivation in natural forests which is still in use today, thus creating a sustainable ecological system and land use mode. The traditional protection by local people helps tea plantations of Jingmai mountain remain their vitality and free of damage in thousand years’ evolution.
