Abstract:

From May to September of 2012, we investigated black-necked cranes (Grus nigricollis) at the Ruoergai Wetland National Nature Reserve, Sichuan, China. A total of 287 individuals were recorded. Seventy individuals were recorded in May, of which 36 belonged to 18 breeding pairs (51.4%), 27 to three groups of more than 4~8 birds (38.6%) and 7 were single (10.0%). In July, 121 black-necked cranes including 41 breeding pairs (a total of 82 individuals, accounting for 84.5%), 7 single cranes (3.1%) and 1 group of the non-breeding cranes (12 individuals, accounting for 12.4%) were recorded. In September, 96 black-necked cranes including 38 breeding pairs (a total of 76 individuals, accounting for 92.4%), 1 single crane (1.2%) and 1 group of the non-breeding cranes (5 individuals, accounting for 6.1%) were recorded.  No significant change of black-necked cranes distribution was observed compared with the previous findings. Overall, the main breeding habitats of black-necked cranes in protected areas are Yao Laqiao, Na LeqiaoNa Luoqiao and Haqiu Lake, Cuo Lajian and Flower Lake. To protect the black-necked crane and its habitats, several measures such as set long-term and fixed monitoring in these regions, limit grazing intensity in protected areas, prohibit grazing in the core area, and regulate the seasonal use of pasture should be taken for the reasonable recovery use of wetland ecosystem.
