Fossils of Elaphurus bifurcatus, E. chinanensis chia, E. lantianensis have been excavated from the region east of Xiâan and south of Harbin. The modern species of Elaphurus, PÃ¨re Davidâs deer (Milu in Chinese) evolved in the Pliocene period of the Tertiary, according to fossils excavated in southern Japan. During the Pleistocene period, it was known from Manchuria (Hofmann, 2007). During the Holocene, P. davidianus was restricted to swamps and wetlands in the region south of 43Â°N and east of 110Â°E in mainland China (Cao 1992, Zhou, 2007). However, the distribution of P. davidianus shrank and its population declined due to hunting and land reclamation in the swamp areas as human population expanded (Jiang and Li, 1999). P. davidianus had largely disappeared in the wild by the late 19th century, and the last wild animal was shot near the Yellow Sea in 1939.
However, during the Qing Dynasty (1616-1911), the Nanyuang Royal Hunting Garden contained a herd of P. davidianus in its 200 kmÂ² hunting ground. This hunting garden in the southern suburbs of Beijing was predominantly a wetland, consisting of swamps, ponds and lakes crossed by the Yongding River. The area had been sealed off from the outside world since the Yuan Dynasty (1205-1368) as a royal garden. The French missionary PÃ¨re Armand David âdiscoveredâ P. davidianus in the Nanyuan Royal Hunting Garden in 1864. Realising that the deer was an unknown species to the West, he persuaded the wardens to give him hinds and skeletons of an adult male, an adult female and a young male, and sent them to Paris in 1866, where the species was named PÃ¨re Davidâs deer by Milne-Edwards. In 1895, the wall of the Nanyuan Hunting Garden was destroyed by a heavy flood of the Yongding River, and most of the PÃ¨re Davidâs deer escaped and were hunted. Only 20-30 animals survived in the garden. Then in 1900, during the Boxer Rebellion, the garden was occupied by troops and the remaining deer were shot and eaten.
However, before the demise of the royal herd of PÃ¨re Davidâs deer in the Nanyuan Royal Hunting Garden in 1900, the deer had been introduced into private deer collections in the United Kingdom, France and Germany. During the first decade of the 20th century, the 11th Duke of Bedford in the United Kingdom gathered the last 18 PÃ¨re Davidâs deer in the world to form a breeding herd at the Woburn Abbey, England. Only 11 of these deer were capable of reproducing (Bedford, 1951-52). Nevertheless, the heavily inbred PÃ¨re Davidâs deer safely passed though the genetic bottleneck of inbreeding and adopted the vast open parkland of an English country estate (Jones et al. 1983).
The captive population started to increase (though with a setback during the First World War due to food shortage), and since the Second World War, the animals started to be spread through captive facilities worldwide, with the first captive animals being sent back to Beijing Zoo in 1956. More recently deer have been sent to China into managed, fenced situation in Beijing, Dafeng, Tianezhou and Yuanyang.
The historic range of E. davidianus was northeastern and east-central China (Nowak, 1999). Truly wild specimens disappeared from the area sometime around 200 A.D., but because a captive herd was maintaind in the Imperial Hunting Park, the species has survived.
Biogeographic Regions: oriental (Native )
E. davidianus has reddish to deep reddish brown summer pelage with a medial black stripe down the shoulders. Winter pelage is grayish brown with darker areas on flanks and throat. Both sexes have a dark tail tassel on their relatively long tail. The skin between the hooves is naked (Nowak ,1999).
Pere David's deer range from 1,830 to 2,160 mm from head to the base of the tail. The tail adds another 220-355 mm. Male E. davidianus weigh about 214 kg and females about 159 kg. Males have antlers that are shed annually in December or January (Nowak, 1999). New antlers immediately begin growing and reach full size by May (Huffman, 2001). Antlers are around 55-80 cm along the curve and fork close to the skin (Harper, 1945). The long hind prong is very straight, and the front prong branches off with the prongs facing backwards. Males also have a maned throat (Nowak,1999).
Immature E. davidianus are spotted white with an average birth weight of about 11 kg (Nowak ,1999).
Range length: 1,830 to 2,160 mm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: male larger; ornamentation
Average mass: 186500 g.
Habitat and Ecology
Historically, E. davidianus were probably found in the lowlands of China, swampy areas and reed-covered marshlands (Nowak, 1999). Today they survive in the wild in two national parks: Beijing Milu Park and the Dafeng Milu Natural Reserve. This species can also be found in captivity in many zoos around the world.
Habitat Regions: temperate
Wetlands: marsh ; swamp
E. davidianus are herbivores and their diet consists mainly of grasses. During summer they will eat many aquatic plants (Nowak, 1999).
Plant Foods: leaves
Primary Diet: herbivore (Folivore )
It is difficult to assess the ecosystem role of such a rare animal. Historically, at least, these deer were probably important in maintaining habitats through their foraging behavior. They probably also provided food to predators.
Because there are no real wild populations of this species, information on predation is not available.
Life History and Behavior
The maximum longevity record is 23 years and 3 months. Average life span is about 18 years (Huffman, 2001).
Status: captivity: 23 (high) years.
Status: captivity: 18 years.
Status: wild: 18.0 years.
Status: wild: 23.3 years.
Lifespan, longevity, and ageing
Males engage in mock combat and real fights during the rut. A male joins a group of females which he thus defends from other males. Stags lose weight rapidly because they don't eat while they defend the harem, and they are succeeded by new stags as the rut continues. After leaving the harem, the male begins to feed again, and will quickly regain his weight.
Mating System: polygynous
Sexual maturity for females is about 2 years and 3 months (Nowak, 1999), and males mature about a year later. About two months before breeding season in June, males will leave the herd. They will rejoin a harem of females and fast during the rut. When fighting, males will use antlers, teeth, and will even rise up on hind legs and box with their front legs. Females have an approximately 20 day long estrous cycle (Nowak, 1999), and within a breeding season can have multiple cycles. The gestation period is about 280 days and one or two fawns are born in April or May (Jiang et al., 2001). Fawns weigh about 11 kg at birth. After the rut, males will leave the herd again for another two months and begin feeding (Brinklow,1993).
Development in species has not been reported. The gestation period is unusually long, however, and an embryonic diapause may occur (Nowak, 1999).
Breeding season: Young are born in April and May.
Average number of offspring: 1-2.
Average gestation period: 9.33 months.
Average age at sexual or reproductive maturity (female): 27 months.

The first conservation reintroduction of PÃ¨re Davidâs deer to China included two groups, of 20 deer (5 males : 15 females) and 18 deer (all females), in 1985 and 1987, respectively. All 38 deer were donated by the Marques of Tavistock of Woburn Abbey, and the transportation was sponsored by the World Wildlife Fund (WWF). After a careful search and evaluation by a group of zoologists, botanists, wildlife managers and officers, the relic site of the Nanyuang Royal Hunting Garden in the southern suburbs of Beijing was chosen as the site of re-introduction, creating the Beijing Milu Park (39Â°07'N, 116Â°03'E), with an area of 60 ha. The deer in the park have received supplemental feeding year round (Jiang et al. 2000a).
The second re-introduction of E. davidianus was carried out in August of 1986, organized by former Ministry of Forestry and WWF. A group of 39 PÃ¨re Davidâs deer was selected from five zoological gardens in the United Kingdom, with the deer mainly from the Whipsnade Wild Animal Park. An extensive search which covered a vast area in eastern China for a potential reintroduction site was conducted before a decision was made. The Dafeng State-Owen Forestry Farm was chosen, on the Yellow Sea coast in eastern China in a lightly populated area (semi-fossils of PÃ¨re Davidâs deer have been excavated from the neighbouring counties, so this site is probably in its natural habitat). The introduced herd was released into three fenced paddocks, each about 100 ha in area. The reserve purchased another 30 kmÂ² land in 1995, more than doubling its original size. In 1997, the Dafeng Milu Natural Reserve was approved by the National Nature Reserve Commission as a national nature reserve. The Dafeng Milu Nature Reserve has the potential to host a large population of PÃ¨re Davidâs deer. The reserve has kept the reintroduced PÃ¨re Davidâs deer and their offspring on its land, and in 1998 the first group of deer was released from the paddocks into the wider reserve (Hu and Jiang 2002). In 2003, and 2006 another two groups of deer were released from the paddocks. There were 950 PÃ¨re Davidâs deer in the reserve in 2006. The annual average population growth rate of deer in the reserve was 17.01%. This PÃ¨re Davidâs deer conservation strategy calls for further expanding of the Dafeng Milu Nature Reserve (Jiang et al., 2000b).
The Beijing Milu Park is in a suburb of the national capital with a limited area and is engulfed by city development, whereas the Dafeng Milu Nature Reserve is located in a remote costal region with little human settlement, where it is possible to acquire more land for conservation. Therefore, the Beijing Milu Park while keeping a healthy nuclear breeding herd of about 100 deer at the park, has shipped PÃ¨re Davidâs deer to other sites in east China (Yang, 2007). The translocations thus reduced the grazing pressure on the park vegetation and expanded the distribution range of the PÃ¨re Davidâs deer in the country. The average annual population growth rate for PÃ¨re Davidâs deer in Beijing Milu Park from 1987-1997 was 17.3%. This PÃ¨re Davidâs deer conservation strategy calls for an expansion of this artificial dispersal of animals to establish new sites (Jiang et al., 2000b).
E. davidianus from the Beijing Milu Park have been relocated to the lower reaches of the Yangtze River in eastern China and Hainan Island in the South China Sea. In October 1993, a group of 30 PÃ¨re Davidâs deer (8 males : 22 females) arrived and was released in a paddock on a small peninsular in the Yangtze River, Tianezhou (29Â°49'N,112Â°33'E). This site was then established as the Tianezhou Milu Nature Reserve in 1993. The size of the reserve is 11.67 kmÂ². Another group of 34 PÃ¨re Davidâs deer (10 males : 24 females) was transferred from the Beijing Milu Park to the Tianezhou paddock in the following year to enlarge the population. An additional 30 deer (15 males : 15 females) were released into the paddock of the reserve in 2002. The relocated deer reproduced in the second year after the relocation (Yang et al, 2002). By the end of calving season of 2006, there were 522 E. davidianus in the Tianezhou Milu National Nature Reserve. The annual average population growth rate was 22.2%. The birth rate and population growth rate in Tianezhou were significantly higher whereas the mortality rate was significantly lower than those of the Dafeng.
In November, 2002, 30 E. davidianus (14 males : 16 females) from Beijing Milu Park and 20 from the Dafeng Milu Nature Reserve were introduced to Yuanyang Forestry Farm, Henan. These deer are in an enclosure on the Yuanyang Yellow River Nature Reserve (35Â°11'N, 114Â°15'E). In 2006, there were 53 deer in the Yuanyang Yellow River Nature Reserve paddock, but the sex ratio was predominately male biased (38 males : 15 females) (Li et al. 2007).
Currently, there are a total of 53 herds of E. davidianus in China. Nine herds have fewer than 25 deer, 75.5% have fewer than 10 deer (Yang et al., 2003). Such a small herd size raise question about the effective population size and health of population genetics, since those herds are isolated and there is no gene exchange. The artificially dispersed E. davidianus herds are similar to a meta-population. The viability of the meta-population depends on the man-made gene exchange process by the managers.
Recommended conservation action includes:
1. Establish additional populations when and where appropriate, with the aim of re-establishing a genuinely wild, free-ranging population.
2. Establish a genetic management programme of all populations in China.
3. Develop conservation education programmes to raise conservation awareness among the local people and general public.
Following a trial release of this species in the Dafeng Reserve, China, Hu and Jiang (2002) concluded that future releases will necessitate either natural or artificial boundaries to alleviate conflict between introduced E. davidianus and farmers, on whose land the deer are likely to stray. These authors suggest a reintroduction model based on that of Oryx leucoryx in Oman (Stanley Price 1989).

Père David's deer
|Père David's deer|
Père David's deer (Elaphurus davidianus), also known as the milu (Chinese: 麋鹿; pinyin: mílù) or elaphure, is a species of deer that is currently extinct in the wild—all known specimens are found only in captivity. This semiaquatic animal prefers marshland, and is native to the subtropics of China. It grazes mainly on grass and aquatic plants. It is the only extant member of the genus Elaphurus. Based on genetic comparisons, Père David's deer is closely related to the deer of the genus Cervus, leading many experts to suggest merging Elaphurus into Cervus, or demoting Elaphurus to a subgenus of Cervus.
Naming and etymology
This species of deer was first made known to Western science in 1866 by Armand David (Père David), a French missionary working in China. He obtained the carcasses of an adult male, an adult female and a young male, and sent them to Paris, where the species was named Père David's Deer by Alphonse Milne-Edwards, a French biologist.
The species is sometimes known by its informal name sibuxiang (Chinese: 四不像; pinyin: sì bú xiàng; Japanese: shifuzō), literally meaning "four not alike", which could mean "the four unlikes" or "like none of the four"; it is variously said that the four are cow, deer, donkey, horse (or) camel, and that the expression means in detail:
- "the hooves of a cow but not a cow, the neck of a camel but not a camel, antlers of a deer but not a deer, the tail of a donkey but not a donkey."
- "the nose of a cow but not a cow, the antlers of a deer but not a deer, the body of a donkey but not a donkey, tail of a horse but not a horse"
- "the tail of a donkey, the head of a horse, the hoofs of a cow, the antlers of a deer"
- "the neck of a camel, the hoofs of a cow, the tail of a donkey, the antlers of a deer"
- "the antlers of a deer, the head of a horse and the body of a cow"
By this name, this undomesticated animal entered Chinese mythology as the mount of Jiang Ziya in Fengshen Bang (translated as Investiture of the Gods), a Chinese classical work of fiction written during the Ming Dynasty.
The adult Père David's deer reaches a head-and-body length of up to 1.9–2.2 meters (6.2–7.2 ft) and stands about 1.2 meters (3.9 ft) tall at the shoulder. The tail is relatively long for a deer, measuring 50–66 centimeters (20–26 in) when straightened. Weight is between 135 and 200 kilograms (298 and 441 lb). The head is long and slender with large eyes, very large preorbital glands, a naked nose pad and small, pointed ears.
The branched antlers are unique in that the long tines point backward, while the main beam extends almost directly upward. There may be two pairs per year. The summer antlers are the larger set, and are dropped in November, after the summer rut. The second set—if they appear—are fully grown by January, and fall off a few weeks later.
The coat is reddish tan in the summer, changing to a dull gray in the winter. Long wavy guard hairs are present on the outer coat throughout the year, with the coat becoming woolier in winter. There is a mane on the neck and throat and a black dorsal stripe running along the cervicothoracic spine. The tail is about 50 centimeters (20 in) in length, with a dark tuft at the end. The hooves are large and spreading, and make clicking sounds (as in the reindeer) when the animal is moving.
The gestation period is about nine months, after which a single offspring is usually born; twins are born in rare cases. The juveniles (referred to as either fawns or calves) have a spotted coat, as is commonly seen in most species of deer. They reach sexual maturity at about 14 months. Historically, their main predators are believed to have been tigers and leopards. Despite no longer encountering ancestral predators, when experimentally exposed to images and stimuli relating to these big cats, the deer seemed to instinctively react with a cautious predator response typical of wild deer.
A semiaquatic animal, Père David's deer swims well, spending long periods standing in water up to its shoulders. Although predominantly a grazer, the deer supplements its grass diet with aquatic plants in the summer.
In neolithic times, the milu's range extended across much of China Proper. Archaeologists have found milu antlers at settlements from the Liao River in the north to Jiangsu and Zhejiang Province and across the Yellow and Yangtze River Basins in Shaanxi and Hunan Province.
Extinction in China
In the late 19th century, the world's only herd belonged to Tongzhi, the Emperor of China. The herd was maintained in the Nanyuang Royal Hunting Garden in Nan Haizi, near Peking. In 1895, one of the walls of the hunting garden was destroyed by a heavy flood of the Yongding River, and most of the animals escaped and were killed and eaten by starving peasants. Fewer than thirty Père David's Deer remained in the garden. Then in 1900, during the Boxer Rebellion, the garden was occupied by troops and the remaining deer were shot and eaten, leaving the animal extinct in its native China.
A few of the deer had previously been illegally transported to Europe for exhibition and breeding. After the extirpation of the Chinese population in 1900, Herbrand Russell, 11th Duke of Bedford, was instrumental in saving the species. He acquired the few remaining animals from European zoos and nurtured a herd at Woburn Abbey. Threatened again by both World Wars, the species survived largely due to the efforts of Bedford and his son Hastings, later 12th Duke of Bedford. The current world population, now found in zoos around the world, stems from the Woburn Abbey herd.
Reintroduction of Père David's deer to China began in 1985, with a herd of 20 deer (5 males and 15 females). This was followed in 1987 by a second herd, consisting of 18 deer (all females). Both herds had been drawn from the Woburn Abbey herd and were donated by the 12th Duke's grandson and successor, John. The transportation was sponsored by the World Wildlife Fund. The relic site of the Nanyuang Royal Hunting Garden in the southern suburbs of Beijing was chosen as the site of re-introduction, creating the Beijing Milu Park. The population in China expanded to around 2,000 in 2005.
A second re-introduction into China was conducted in 1986 where 36 Père David’s deer were chosen from five UK zoological gardens with the bulk of the deer coming from Whipsnade Wild Animal Park. These deer were introduced into Dafeng Milu Nature Reserve, near the Yellow Sea coast in eastern China. In 2006 the population at this Nature Reserve had reached around 950 with an average annual population increase of 17%.
In 1993, 30 deer taken from the herd at Beijing Milu Park were released into the Tianezhou Milu National Nature Reserve. These were followed by another 34 deer taken from Beijing Milu Park and released into the Tianezhou Reserve. The average annual population growth rate for Père David’s deer in Tianezhou Nature Reserve was 22.2%.
In 2002, 30 deer taken from the herd at Beijing Milu Park and 20 from Dafeng Nature Reserve were released into the Yuanyang Yellow River Nature Reserve.
When the species was assessed for the IUCN Red List (1996), it was classified as "critically endangered" in the wild, under criterion "D": "[wild] population estimated to number less than 50 mature individuals". Since October 2008, they have been listed as extinct in the wild, as all populations are under captive management. In spite of the small population size, the animals do not appear to suffer genetic problems from the genetic bottleneck. The captive population in China has increased in recent years, and the possibility remains that free-ranging populations can be reintroduced in the near future.
Legend and cultural significance
According to Chinese legend, when the tyrant King Zhou of Shang ruled the land more than 4,000 years ago, a horse, a donkey, an ox and a deer went into a cave deep in the forest to meditate and on the day the King executed his virtuous minister Bigan, the animals awoke from their meditation and turned into humans. They entered society, learned of the King's heinous acts and wanted to take recourse against the King, who was powerful. So they transformed themselves into one creature that combined the speed of the horse, the strength of the ox, the donkey's keen sense of direction and the nimble agility of the deer. This new animal then galloped to the Kunlun Mountains to seek the advice of the Primeval Lord of Heaven. The Lord was astonished at the sight of a creature that had antlers of a deer, hooves of an ox, face of deer and tail of a donkey. "It's unlike any of four creatures!" he exclaimed. Upon learning of the animal's quest, Lord gave his blessing and dispatched the creature to his disciple the sage Jiang Ziya, who was battling the King. Jiang Ziya rode the creature to victory over the King and helped found the Zhou Dynasty. After fulfilling its vow, the milu settled in the lower reaches of the Yangtze River. The animal became a symbol of good fortune and was sought by later emperors who believed eating the meat of the milu would lead to everlasting life. By the Han Dynasty, about 2,000 years ago, the milu was already extinct in the wild, but kept in imperial hunting grounds.
