Muntiacus gongshanensis can be found in Southern China, Tibet, Myanmar, and Northern Thailand. (Macdonald and Norris, 2001)

Muntiacus crinifrons, which resembles in appearance. has small, dagger like antlers, which are hidden in a tuft of reddish colored hair. Females can reach 57 to 61 centimeters in height, where males only reach 47 to 52 centimeters in height, both sexes weigh between 18 and 20 kilograms (Macdonald and Norris, 2001). However, a weight of 24 kilograms was reported for a male in one study (Schaller and Vrba, 1996). (Macdonald and Norris, 2001; Schaller and Vrba, 1996)has a dark, chestnut brown coat and may be conspecific with

Reproduction behavior of Muntiacus reevesi, males demarcate and aggressively defend small territories against other males. These territories may overlap with several female territories. (Lu and Sheng, 1984; Nowak, 1999; Wood and Myers, 2006)is not documented, however, in
- Mating System
Little is known about mating systems in Muntiacus crinifrons, breeding occurs continuously throughout the year. They have no distinct breeding season and females may go into estrous before reaching full body size. In one study, it was found that some lactating females were carrying fetuses, indicating that post-partum estrous occurs in this species. Although the gestation period is not known for , in Muntiacus reevesi gestation lasts between 209 to 220 days. Typically a single young is born, twins are rare. (Geist, 1998; Nowak, 1999; Wood and Myers, 2006). In their close relative,

Nothing is known about parental care in Muntiacus, however, maturation progresses quickly and females can carry one developing young in the uterus while nursing another. Both sexes develop rapidly, becoming independent within 6 months after birth. (Dueling and Myers, 2004; Geist, 1998; Wood and Myers, 2006; Worlddeer, 2005). In other species of

No studies have been done on the behavior of M. crinifrons. Muntiacus crinifrons is solitary and very territorial. When a male enters another male’s territory, the resident male attacks the other male, using their large, tusk-like, upper canines. Muntiacus crinifrons defend their territories from conspecifics as well as other deer species. Muntjac species are generally active at dusk and dawn. (Geist, 1998; Lu and Sheng, 1984; Nowak, 1999; Wood and Myers, 2006). However, it is probably similar to that of the close relative,
Nothing is known about the home range of M. reevesi that were released in England had home ranges of approximately 20 ha and females had home ranges of approximately 12 ha. (Nowak, 1999; Wood and Myers, 2006; Nowak, 1999; Wood and Myers, 2006; Nowak, 1999; Wood and Myers, 2006), but
Communication and Perception
No studies have been done on this topic for M. crinifrons individuals use secretions from frontal and preorbital glands to mark territorial boundaries. They also use scents to indicate reproductive status. Muntiacus crinifrons uses visual signals. For instance, the white fur on the underside of the tail can be used to show a predator or an opponent that they have been detected. A raised frontal tuft can have the same meaning. Auditory signals may also be used, such as a barking sound used when a predator has been detected. Male M. reevesi use low postures and buzzing noises during courtship. (Dueling and Myers, 2004; Geist, 1998; Nowak, 1999; Wood and Myers, 2006). However,
Not much has been reported on the food habits of muntjac species are described as omnivorous, however, the closely related species, M. crinifrons, seems to be mainly herbivorous. A study of stomach contents showed that the diet is made up of fruits, twigs, and leaves. (Lu and Sheng, 1984; Wood and Myers, 2006). Most

Little is known about predation on Gongshan muntjacs, but humans are suspected of being important predators. In M. crinifrons dholes and leopards are important predators. Some species of Muntiacus flee from predators on well maintained trails and hide in dense undergrowth. (Dueling and Myers, 2004; Geist, 1998; Lu and Sheng, 1984; Nowak, 1999; Wood and Myers, 2006; Worlddeer, 2005)
- Known Predators
- humans (Homo sapiens)
Gongshan muntjacs are likely to be important in tree seed dispersal in their native ecosystems. They are also important prey for large predators, such as leopards. (Geist, 1998; Lu and Sheng, 1984; Wood and Myers, 2006)
- Ecosystem Impact
- disperses seeds
Economic Importance for Humans: Positive
Gongshan muntjacs are hunted by native populations for their meat, horns, and hides. They are also important members of healthy, native ecosystems. (Lu and Sheng, 1984; Rabinowitz and Khaing, 1998; Rabinowitz, et al., 1998; Sheng and Lu, 1980; Wood and Myers, 2006; Worlddeer, 2005)
- Positive Impacts
- body parts are source of valuable material
Economic Importance for Humans: Negative
There is controversy regarding the taxonomic status of Gongshan muntjacs. “ Muntiacus gongshanensis has always been problematic since it was described on the basis of a single, odd karyotype" (C. P. Groves, pers. comm.). Amato, Eagan, and Rabinowitz (1999) suggest that M. crinifrons and should be treated as a single taxon because morphological and molecular data from multiple specimens does not diagnose as distinct. They suggest that further study must be done. (Amato, et al., 1999)
