This vast swamp meadow is located on the Qinghai-Tibet Plateau at 4,800 metres above sea level. With permanent and seasonal pools and lakes, the wetland forms one of the sources of the Lhasa River. It is one of the highest altitude wetlands in China and indeed the world, performing major hydrological functions such as control of soil erosion and prevention of seasonal floods. Maidika also has an important role in providing water for residents as well as acting to retain sediment and sequester carbon. The wetland plays a critical role as a staging and breeding habitat for migratory waterfowl, including the vulnerable black-necked crane (Grus nigricollis) and the common pochard (Aythya ferina). The endangered snow leopard (Panthera uncia) and the endangered saker falcon (Falco cherrug) can also be found within the site. Over-grazing and reduced rainfall as a result of climate change are present threats to the ecological character. The lands are state-owned and are managed by the Bureau of Maidika Wetland in Chali County.

Administrative region: 
This Ramsar site is administratively located in Chali County of Nakchu District, Tibet Autonomous Region, Western China.
