Lang Bian White-Bellied Rat (Niviventer langbianis)
This species is found in Myanmar, Thailand (North of
the Isthmus of Kra), Southwestern Cambodia, Lao PDR, Vietnam, and northeastern
India (Margherita in Assam [Molur et al. 2005]). It is present in southern China
(a single site in Yunnan) (Smith and Xie 2008). It has an altitudinal range of
roughly 200 to 1,600 m asl.
China; India; Lao People's Democratic Republic; Myanmar; Thailand; Vietnam
In Southeast Asia, it is widespread but not particularly
abundant at any site. There is no information available on the population
abundance of this species in South Asia (Molur et al. 2005).
Population Trend: Decreasing
Habitat and Ecology:
This species is arboreal, but commonly captured on the ground.
It is primarily found in tropical evergreen rainforest formations, but there are
records from mixed deciduous seasonal forest (Marshall 1977). Throughout its
range, this species is found with N. fulvescens in the same habitats (Musser and
Carleton, 2005). It can be found in lightly disturbed, but not secondary forest
(Guy Musser pers. comm.). In South Asia, it can be found in both primary and
secondary habitat (Molur et al. 2005)
The habitat of this species is generally being deforested over
its range for timber, firewood and conversion to agricultural land.
It is presumably present in several protected areas. It is not known from any protected area in India. It is listed in the Schedule V (considered as vermin) of the Indian Wildlife (Protection) Act, 1972. General field surveys, research into the natural history and monitoring of populations are recommended for this species (Molur et al. 2005).
