Namdapha National Park and Tiger Reserve in the Changlang District of Arunachal Pradesh in northeastern India are rich in biodiversity. The dense evergreen forest of the park with high canopy coverage supports a variety of fauna including primates. In February, 2002, we surveyed the primates in Namdapha National Park to assess their status. We directly sighted, 5 species of diurnal primates, and secondary information shows the presence of stump-tailed macaques and slow lories. We encountered 10 groups of hoolock gibbons (33 individuals), 9 troops of capped langurs (61 individuals), 15 groups of Assam macaques (209 individuals), 6 groups of rhesus macaques (74 individuals) and one unidentified group of macaques (15 individuals). Hunting, rather than habitat destruction, is the chief potential threat for primates in the park. 相似文献

Systematic studies of the Borajan Reserve Forest in Assam, India, were conducted in 1995, 1997, and 1998. Initially this small
(5 km2) forest was inhabited by substantial numbers of five species of diurnal primates and the forest was typical of Reserve Forests
in northwest upper Assam. About two thirds of the forest had canopy cover of 20 – 50% or more. Civil unrest, political problems
and a lack of resources for Forest Department personnel, however, resulted in rapid degradation of the area. After three years
less than one third of the forest had more than 20% canopy cover; all primate populations had declined dramatically and the
small percentage of juveniles in each species indicated that all were in imminent danger of local extinction. There was no
evidence of hunting or trapping nor any large scale logging. Forest degradation was due primarily to small scale harvesting
of forest products, selective cutting, and collection of firewood. Although only hand tools were employed, the forest inexorably
declined in response to these steady pressures. Borajan may be an object lesson as to what can happen but it need not be the
harbinger of Assam’s future. 相似文献
