Site description Located in the Zhongden area of north-western Yunnan. The IBA is a high-altitude marsh, surrounded by high mountains (3,800-4,449 m) in the east, west and north. The lake extends 10 km from north to south and 2.3 km from east to west, and there is 500 ha of open water even in the dry season. There are also shallow water marshes and meadows, which are the main habitats for wintering Grus nigricollis.

IBA Monitoring

2008 medium not assessed medium
unset
Medium - based upon reliable but incomplete / partially representative data

Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - nomadic grazing happening now small area/few individuals (<10%) slow but significant deterioration low
Energy production and mining mining and quarrying happening now small area/few individuals (<10%) slow but significant deterioration low
Human intrusions and disturbance recreational activities happening now small area/few individuals (<10%) slow but significant deterioration low
Over-exploitation, persecution and control of species direct mortality of trigger species - hunting and trapping happening now small area/few individuals (<10%) slow but significant deterioration low
Pollution agricultural and forestry effluents and practices likely in long term (beyond 4 years) some of area/population (10-49%) slow but significant deterioration medium

Most of site (50-90%) covered (including the most critical parts for important bird species)  A management plan exists but it is out of date or not comprehensive  Substantive conservation measures are being implemented but these are not comprehensive and are limited by resources and capacity  medium
