Pater Davids Hirsch oder Milu (Elaphurus davidianus Milne Edwards, 1866), 150 Jahre, 1865 bis 2015

The population of the Père David's deer or milu (Elaphurus davidianus), which was discovered in China by Père Armand David in 1866, has grown from five, or even merely three individuals, imported from China to approximately 5000 during a time-span of 140 years. We tried to find out more about the origin of the 18 individuals which formed the original herd of the 11^th Duke of Bedford at Woburn Abbey. His breeding-group was the only safeguard for this species between the years 1900 and 1946. Of the 18 individuals three were offspring of Berlin Zoo, three originated from Cologne Zoo and probably all the rest came from the Jardin d‘Acclimatation in Paris. The origin of the breeding herd at the Jardin d‘Acclimatation is not clear. The first individuals either came from Berlin Zoo or were imported directly from China in the years between 1876 and 1886. In Berlin Zoo's breeding records there is a remarkable gap for the years 1879 and 1880. If they came from Berlin Zoo, the imported male and two females would be the sole founders of the herd, and if the Jardin d‘Acclimatation had done an own import, then there would be at least five founders. At Berlin Zoo at least 18 milu calves were born between the years 1878 and 1895. The final destinations of most of these could be traced in literature. Some of them are not quite conclusive yet. We sketched the development of the worldwide zoo-stock of Père David's deer, the return to China and the re-settlement in the original habitat in newly established reserves and finally even outside the reserves. After centuries the milu has again gained the status of a free-living species thanks to the efforts of several zoological gardens, the Dukes of Bedford and the Chinese conservation authorities.
