Abstract: Père David's deer (Elaphurus davidianus) have been studied since the establishment of a captive herd at the Dafeng Milu Nature Reserve, Jiangsu, in 1986. During calving season, we counted neonates every ten days. By dynamically monitoring and counting individuals in the captive-bred and the wild herds,we documented growth rates. We weighed individuals of differing ages and both sexes. The captive herd at Dafeng increased rapidly, from 39 reintroduced in 1986 to 706 in 2004. During this period, mean natality was 21.9% and mean net growth rate was 17.5% . This herd has produced a the 4th-generation (F4). Thirty-one individuals were released into the wild during 1998-2003,and the population numbered 41 in 2004. Mean natality was 16.3% and mean net growth was 9.0%.Two 2nd-generation (F2)individuals were born (1 each in 2003 and 2004). These results suggest that Père David's deer have adopted to the Yellow Sea coastal environment in northern Jiangsu. Human activity is an important factor affecting re-establishing the wild Père David's deer population.
