Three Parallel Rivers of Yunnan Protected Areas

The Three Parallel Rivers of Yunnan Protected Areas is a UNESCO World Heritage Site in Yunnan province, China. It lies within the drainage basins of the upper reaches of the Yangtze (Jinsha), Lancang (Mekong) and Nujiang (Salween) rivers, in the Yunnanese section of the Hengduan Mountains.

The protected areas extend over 15 core areas, totalling 939,441.4 ha, and buffer areas, totalling 758,977.8 ha across a region of 180 km by 310 km. Here, for a distance of over 300 km, three of Asia’s great rivers run roughly parallel to one another though separated by high mountain ranges with peaks over 6,000 meters. After this area of near confluence, the rivers greatly diverge: the Nujiang River becomes Salween and empties out at MoulmeinBurma, into the Indian Ocean, the Lancang becomes the Mekong and south of Ho Chi Minh CityVietnam, empties out into the South China Sea and the Yangtse flows into the East China Sea at Shanghai. Selected nature reserves and places of scenic beauty in this unique region were collectively awarded World Heritage Site status in 2003 for their very rich biodiversity and outstanding topographical diversity.

Running parallel to these three rivers, but to the west inside Burma, is the river gorge of the N’Mai river, the main tributary to the Irrawaddy River.

In its description, UNESCO mentions: “(It) may be the most biologically diverse temperate region on earth” and “An exceptional range of topographical features – from gorges to karst to glaciated peaks — is associated with the site being at a ‘collision point’ of tectonic plates“.

Due to its topography and geographical location, the Three Parallel Rivers region contains many climate types. Average annual precipitation ranges from 4,600mm in the Dulongjian area in the west of Gongshan county to 300mm in the upper valleys of the Yangtse river. The protected areas are home to around 6,000 species of plants, 173 species of mammals, and 417 species of birds. Many of the flora and fauna species are endemic to the region.

Although this region has been acknowledged as a natural World Heritage Site, its demographic make-up also is highly interesting as it contains many of the twenty-five minorities found in Yunnan province including the Derung, the smallest of all of China’s minority groups. Some of the other minorities found in this region are the Tibetan people, the Nu peopleLisuBaiPumi and Naxi. Many of these minorities still use traditional costumes as their normal daily attire.

In the same region as the Three Parallel Rivers of Yunnan Protected Areas lies the Old Town of Lijiang, which is also a World Heritage Site in its own right.
