STATUS OF PHAYRE’S LANGUR Trachypithecus phayrei IN SATCHARI NATIONAL PARK,BANGLADESH

摘要

We studied the population status of Phayre’s Langur in Satchari National Park,Bangladesh,and threats to this population,from January to December 2016.We recorded 23 individuals in three groups.Group size ranged from four to 12 (mean 7.7±4.0) individuals; all groups contained a single adult male,1–4 females and 2–7 immature individuals (subadults,juveniles and infants).Habitat encroachment for expansion of lemon orchards by the Tipra ethnic community and habitat degradation due to logging and firewood collection are the main threats to the primates.Road mortality,electrocution and tourist activities were additional causes of stress and mortality.Participatory work and awareness programmes with the Tipra community or generation of alternative income sources may reduce the dependency of local people on forest resources.Strict implementation of the rules and regulations of the Bangladesh Wildlife (Security and Conservation) Act 2012 can limit habitat encroachment and illegal logging,which should help in the conservation of this species.
