The Nannuoshan Tea Forest represents the tea culture of the Hani people, a minority ethnic group in Xishuanbanna. In addition, the biodiversity is so rich because of the elevation and climate. Forests located at an altitude between 1,500 to 1,600 meters are generally called monsoon evergreen broad-leave forests and forests above an altitude of 1,600 meters are called mid-montane humid evergreen broad-leave forests. Nannoushan is located at an altitude of 1,600 meters at the border of two climate zones, which explains why both tree species can be found in Nannoushan. High altitude areas in this region are also called High Altitude Wetlands because at higher altitudes, the air temperature drops, water vapor condenses, air humidifies and rainfall is more frequent. South Yunnan is located in a tropical mountainous area. The high elevation contributes to the vivid climate. South Yunnan is located in a high altitude area ranging from 67 to 3,000 meters, up to 4,000 meters above sea level. The mountain is located in a low altitude area which accounts for various climates and a rich biodiversity.The local economy exists symbiotically with the local ecology. The Dai people live in a low altitude region (the basin) and the Hani people live in the mountains. The local biodiversity is affected by the climate and living conditions of the respective groups. Both tea and bamboo cultures can be found in Nannuoshan. The blending of the two cultures is common in Yunnan.
