1. Profile (Picture)
The Truong Son muntjac was first recorded by scientists during a survey of forests in the Truong Son (formerly "Annamite") range of mountains in Vietnam in April 1997. It weighs approximately 15 kg (33 lb) and is found mostly in secondary wet evergreen forest, with ferns and leaf litter in the dense undergrowth, in higher ridges from 400 - 1000 m (1300 - 3300').
Detailed information about its biology is not yet available. Generally, it has been found that young muntjacs are born in dense jungle growth, where they remain hidden until they can move around with their mother. The diet of muntjac species includes grasses, low-growing leaves, and tender shoots, and both diurnal and nocturnal activity have been reported. (Nowak 1999)
*** Locally, the Truong Son muntjac is called "sam coi cacoong," which means "the deer that lives in the deep, thick forest."
*** The scientific name selected for this species, Muntiacus truongsonensis, refers to the Truong Son (formerly "Annamite") range of mountains. This follows the recent custom of naming newly identified mammal species for geographic locations near where they were first found. Such species include: the saola, named Pseudoryx nghetinhensis for the two Vietnamese provinces Nghe An and Ha Tinh; the giant muntjac, named Megamuntiacus vuquangensis for the Vu Quang Nature Reserve in Vietnam; the leaf muntjac, named Muntiacus putaoensis for the town, Putao, nearest to where it was found in Myanmar; and the Tainguen civet, Viverra tainguensis, named for the Tainguen Plateau in Vietnam where it was originally found. (Amato et al. 1999, Rozhnov & Pham Trong Anh 1999, Wikramanayake 1999)
*** Muntjacs are also known as "barking deer" because they make a deep, barklike sound as a warning if they sense a predator nearby.
The Truong Son muntjac was discovered by scientists during a survey of forests of the northern Truong Son range around West Quang Nam Province in central Vietnam. After DNA analysis it was confirmed as a new species in August 1997. (Wikramanayake 1999)
The Truong Son muntjac is one of several new species found in the Truong Son mountains and described by scientists only recently. These species have not been identified previously because years of armed conflict, steep and rugged terrain and remoteness have precluded scientific exploration of this region until recently.
