云南哀牢山新平辖区西黑冠长臂猿种群数量与分布
Population size and distribution of western black crested gibbon(Nomas-cus concolor)in Ailao Mountain,Xinping,Yunnan Province
摘要
Abstract
Population surveys of rare and endangered species play a vital role in making suitable conservation action plans.The western black crested gibbon(Nomascus concolor)is a small arboreal ape mainly distributed in Yunnan Prov-ince,China,with Ailao Mountain,Xinping County as an important distribution site.From March to April and November to December 2022,a comprehensive field survey of western black crested gibbons was conducted in Ailao Mountain,Xinping by monitoring their loud morning calls.The results revealed 178 groups(about 765 individuals)recognized,which indicated the largest population found and a significant population growth compared to the previous survey(124 groups)in 2010.Most groups are located in Ailaoshan National Nature Reserve and the adjacent national forests in the north,with 89 groups in Zhelong(1.04 group/km2)and 50 groups in Shuitang(0.40 group/km2),and 39 groups(0.38 group/km2)in Ailaoshan County Nature Reserve of Xinping in the south.The elevational distribution of the groups ranges from 1 900 to 2 927 m,and most of the groups are distributed from 2 200 to 2 900 m above sea level.One hundred fifty-two groups are found inside nature reserves,with a protection rate of 85.4％.The main threats to the gib-bons in Ailao Mountain,Xinping include population isolation and dispersal limitation by road across the mountain and artificial pine forest belt along the outside of the national nature reserve.Therefore,ecological corridor construction across the road'Enshui'and habitat restoration after cleaning the partial pine forest are suggested to promote population dispersal and exchange,and habitat expansion.关键词
