Subspecies

Four subspecies of the tufted deer are recognized, with one having doubtful taxonomic status: *''E. c. cephalophus'' – the largest subspecies, brownish coat, found in southwestern China and northeastern Myanmar. *''E. c. michianus'' – has a relatively narrow snout, found in southeastern China. *''E. c. ichangensis'' – has a relatively broad snout, with a grey-brown coat, found in Central China. *''E. c. forciensus'' – doubtful subspecies, distribution unclear.


Description

The tufted deer is similar to a
muntjac Muntjacs ( ), also known as the barking deer or rib-faced deer, (URL is Google Books) are small deer of the genus ''Muntiacus'' native to South Asia and Southeast Asia. Muntjacs are thought to have begun appearing 15–35 million years ago, ...
in appearance, but the longer necks and legs give it a slightly leaner appearance. The coat is coarse with short and stiff hairs, being almost black in the winter and chocolate brown in the summer. The lips, tip of the ears, and the underside of the tails are white. A tuft of horseshoe-shaped hair is present on the forehead and upper neck, being brown to black, and can be up to long. Perhaps the most striking feature of this deer is the fang-like canines in the males of the species. These can grow up to long, or longer in rare cases. The tufted deer is a small deer, but still larger than most muntjac species. It stands at at the shoulder, and the weight varies from . The tail is short at around . The antler is only present in males and is extremely short, almost hidden by its long tuft of hair.


Habitat and distribution

The tufted deer is found mainly in China, where it occurs in the south from eastern coast to eastern

. It is absent from the extreme south of the country. There are old records of this species in northeastern Myanmar, but recent surveys failed to find any, possibly due to the lack of surveys on the preferred habitat. Tufted deers are highly distributed animals where it overlaps in its distribution with other species like the Sambar. It inhabits high, damp forests at

s with extensive understory and nearby freshwater supply. In places such as the Gongga Mountain National Nature Reserve. In this area, the plants and trees change as you go higher in altitude. This means that the plants at the lower part of the mountain are mostly subtropical, while the ones at higher parts of the mountain are those that can survive cold, harsh conditions such as snow. The tufted deer's preference for montane forests emphasizes its ability to live in regions with different temperature variation. Additionally, the availability of salt licks is also a positive factor to the presence of this animal. This deer is able to withstand minor human disturbances, and is occasionally found in cultivated lands.


Behavior and reproduction

The tufted deer is mainly solitary or found in pairs. It is

which can lead to male deer fighting over mates. Male adult tufted deer are also known to fight over territory to show dominance. When fighting their main weapon is their elongated canines, and they also use their antlers but they are not as dangerous.


Diet

Tufted deer are herbivorous species. Their diet mainly consists of leaves, twigs, fruit, and different types of vegetation. Tufted deer are considered both grazers and browsers, meaning they feed on both grass and various other vegetation.


Threats and conservation

Surveys from 1998 put the estimated population around 300,000–500,000 individuals, though a substantial, ongoing decline is almost certain. Overharvesting of large animals in China is a serious threat not only to this species. The hide of this deer is a fairly high-end textile material, especially after the vigorous conservation efforts made on other more endangered species. Habitat loss is also an issue in this rapidly developing country. In China, this species is listed as provincially protected species in many places, but it is not protected by the national law. It occurs in a number of protected areas. More study needs to be done on this poorly known species for efficient protection. The tufted deer is part of the yellow species survival plan program by the association of zoos and aquariums, because it cannot maintain 90% gene diversity for 10 generations. To prevent gene diversity to continue dropping, the program plans to work on '' ex situ'' populations by increasing the number of exhibit places in zoos and making sure that animals can breed. Prior to this the tufted deer population was also decreasing in captivity due to lack of interest in the species, even though captive breeding has greatly helped to conserve this species by facilitating
