Population and conservation status of a transboundary group of black snub-nosed monkeys (Rhinopithecus strykeri) between China and Myanmar

  • 摘要: 怒江金丝猴 (Rhinopithecus strykeri) 是新近发现的非人灵长类动物之一,其具体的种群分布,以及各猴群的详细种群结构和保护现状等信息十分匮乏,制约了对该物种的精准保护。自2019年1月至2021年2月,我们对位于中缅边境的云南省怒江州片马地区的怒江金丝猴种群进行了为期26个月的综合调查。我们首次确认该区域目前仅存在1个跨境猴群,猴群时常会越境至缅甸一侧游走活动,其多年家域约51.50–57.02 km²。与2012–2014年报道的约100只相比,当前猴群包含18个OMU家庭单元和2个AMU全雄单元、约155–160只个体,猴群规模是以往的1.5–1.6倍,且当前种群结构显示其已呈现一定的增长趋势。然而调查同样发现,虽然在中国境内已得到较好的保护,但猴群在缅甸一侧活动时会面临严重的盗猎威胁,且缅甸一侧存在开矿和跨境森林火灾等破坏森林栖息地的现象。该研究表明,怒江金丝猴这一极度濒危非人灵长类的种群有望继续增长,但对于跨境种群的特殊性和其所面临的威胁,建议中缅两国政府尽快建立跨境合作机制,强化对跨境种群的保护。

    A: Survey area in Pianma region, Yunnan Province, China. Blue polygon represents current home range based on surveys from 1 January 2019 to 28 February 2021. Purple polygon (C8) and ellipses (C7, C9, C10, and M5) are previously confirmed or provisional group distributions. Group names and ranges follow Chen et al. (2015), Ma et al. (2014) and Meyer et al. (2017). B: Recorded transboundary activities of R. strykeri near border between Gangfang village (China) and Pawaku village (Myanmar). Two captions (in rectangular box) and seven images pinpoint several key locations and dates of transboundary group activities and human disturbances. “PM36GF” and “PM39GF” are camera trap sites that captured images of R. strykeri near the border. Four asterisks (*) indicate interview and acoustic records of species poaching (red) and mining sites (white). Photo of captured infant was provided by an anonymous witness (relative of one of the Pianma region interviewees) in Pawaku village, Myanmar. C: Population and social unit composition of group based on 18 November 2020 census. Order of social units (OMU: one-male, multi-female unit; AMU: all-male unit) on y-axis (from top to bottom) follows temporal sequence during the census.
