Abstract
Using simultaneous land surveys, we monitored the population size and spatial distribution of wintering
Siberian cranes at 64 lakes around Poyang Lake between 1998 and 2010. The results showed that 46 lakes were inhabited
by wintering cranes, and in 25 of those, the number of wintering cranes accounted for more than 1% of the Siberian
cranes’ global population. The lakes where over 40.0% of the global population, e.g. 1 280 individuals, included Dachahu
Lake in Jiujiang region, and Banghu Lake and Candouhu Lake in the Poyang Lake Nature Reserve. The average yearly
population of the wintering Siberian crane in the Poyang lakes was 3 108±849, with the maximum of 4 004 individuals in
winter 2002. On the whole, there was no drastic fluctuation, but population numbers have shown considerable fluctuation
since 2003. We also found the Poyang Lake Nature Reserve was the major wintering area of the Siberian crane, with over
60% of Siberian cranes wintering in the reserve since 2002 (except in 2006). Most of the inhabited lakes are covered in
existing nature reserves, though some lakes outside the reserve were also considerably used by Siberian cranes.
