4 DOUC LANGURS
My Town and Ro Village, Ca Dy Commune, although hunters could not distinguish between Red and
Grey-shanked douc langurs (Ngo Van Tri, in prep.). In contrast, Ha Thang Long (2000) reported that
the two douc forms are well known by hunters (Ca Tu minority). According to hunters, the Redshanked
douc is rather rare in the area. But locals from Tabhing, Chaval and Ladee village close to
the border with Lao PDR, frequently observe Red-shanked doucs.
Grey-shanked observations are higher around Ca Dy village. Grey-shanked douc langurs were
reported from interviews conducted in the area in May 1997 by Vu Ngoc Thanh and Lippold (Vu
Ngoc Thanh, pers. comm.).
One ranger report from Nam Giang FPD noted that four Grey-shanked douc langurs had been hunted
for research in 1998 around Ca Dy village.
DNA investigation of a skull and a tail, collected during the FZS survey in 2000 at Tabhing village,
identified them as belonging to P. cinerea.
One Grey-shanked douc langur female was captured by a villager and sold to a policeman who kept
it as a pet until it was confiscated by Quang Nam provincial FPD in September 2000 and is now
under the care of the EPRC.
Locals confirmed the occurence of P. cinerea in Song Thanh Nature Reserve (Ha Thang Long, 2000;
Ngo Van Tri, in prep.). This Nature Reserve represents an important conservation status for the Greyshanked
douc langur.
Tien Phuoc District (QUANG NAM)
Special use forest: None
Douc status: Occurrence confirmed, last evidence in 1999 (Vu Ngoc Thanh, pers. comm.)
Species recorded: P. cinerea (sighting and living animal)
In May 1999, this area was surveyed with a special focus on the Grey-shanked douc langur. Two
groups of P. cinerea were seen in the forest and one photo was taken by Vu Ngoc Thanh. In addition,
living and dead specimens were seen in Tien Phuoc City market (Vu Ngoc Thanh, pers. comm.).
During a FZS survey in July 2000, based on interviews it was estimated that a population of about 70
to 80 Grey-shanked douc langurs live in the district. The habitat is mostly poor secondary forest.
In January 1998 the EPRC received two confiscated P. cinerea from this district.
