湖北后河国家级自然保护区,地处华中腹地,属武陵山东段余脉的一部分山地。该区域生物多样性高,但近15年来未对该地区的自然资源进行过全面调查。为深入了解该区域野生动物多样性现状及其变化,于2012年7月29日至2014年1月8日,在后河自然保护区设置红外相机监测位点53个,对保护区内的鸟类和兽类进行调查。红外相机共拍到鸟兽的独立有效照片1 963张。经鉴定,可以辨认的兽类共计4目12科19种;鸟类共计...
九连山国家级自然保护区是我国中亚热带与南亚热带常绿阔叶林的过渡地带,动植物种类丰富多样。为进一步掌握该保护区野生动物资源现状,我们于2014年11月至2015年7月在保护区布设了31个红外相机监测点,对大中型兽类和林下活动鸟类进行了初步摸底调查。相机累计工作4 692个捕获日,共获得有动物的独立有效照片3 341张,鉴定出鸟兽物种共10目16科33种(兽类12种,鸟类21种)。属于国家Ⅱ级重点保护...
红外相机技术是监测兽类和鸟类的重要方法,目前已广泛应用于野生动物资源调查、种群评估和行为生态学等研究领域。2014年7月至2015年1月期间,在广西猫儿山国家级自然保护区布设51个红外相机监测位点(分别位于4种生境和7个海拔区域),对区内大中型兽类及林下鸟类资源多样性进行了初步调查。研究期间共记录到兽类17种、鸟类30种,包括2种国家I级和7种II级重点保护野生动物。小泡巨鼠(Leopoldamy...
掌握野生动植物本底资源是各级自然保护区生物多样性监测研究和保护管理的重要环节。为了建立龙溪-虹口国家级自然保护区内兽类和鸟类多样性资源的长期监测机制,于2013年9月至2014年11月,我们采用红外相机技术在龙溪沟和虹口峡谷等区域按公里网格布设了57个监测点,调查地面活动的兽类和鸟类。红外相机累计工作达11,847个工作日,共记录到兽类和鸟类物种61种,其中兽类5目12科21种,鸟类3目10科40...
野生动物多样性的有效保护与管理,需要大范围、长时间的系统监测网络的支持。红外相机调查技术近年来已成为自然保护区鸟兽调查的最有效工具之一,为了解和掌握区域性乃至全国性的生物多样性现状,提供了最直接和最基础的数据。长青国家级自然保护区位于秦岭南坡,地处秦岭自然保护区群的核心地带。自2008年至2011年,使用被动式红外触发相机调查技术在长青保护区内调查了大中型兽类与鸟类的本底资源。共完成有效调查位点4...
