The data of the overwintering population of red-crowned crane in the YNR from 1981 to 2016 came from the monitoring of full line survey on the distribution of red-crowned crane in Yancheng coastal beach organized by the environment protection department of the city from 1981 to 1983 (Lv, 2008, 2009) and the maximum monitoring number of two times (December and January in the next year) simultaneous survey conducted by the researcher and management staff of YNR every year from 1984 to 2016.
Climate data of the wintering period in YNR from 1981 to 2016 was collected from the monthly data set of China's ground climate data, which was downloaded from China Meteorological Data Sharing Service System (http://data.cma.cn/site/index.html).
To estimate the wintering population size of the red-crowned crane in YNR, we analyzed its inter-annual variation from 1981 to 2016.
Mean air temperature of YNR 1981-2016 in wintering period was (4.6 +- 0.1AdegC).
The average population number of red-crowned crane in the YNR during 1981-2016 was (623+-33), the largest number was 1128 in 1999, and the least was 230 in 1981.
