利用红外相机对四川白水河国家级自然保护区鸟兽资源的初步调查

Preliminary surveys of mammals and birds by infrared camera traps in the Sichuan Baishuihe National Nature Reserve

2017年5月至2018年5月,我们在四川白水河国家级自然保护区内设置红外相机对地面活动鸟兽进行了初步调查。布设在24个位点的24台相机累计工作3,832天,共获得可识别物种的独立有效照片535张。经鉴定,兽类有4目10科17种,鸟类有2目4科10种。其中,国家Ⅰ级重点保护野生动物5种,国家Ⅱ级重点保护野生动物8种,中国豪猪(Hystrix hodgsoni)、宝兴歌鸫(Turdus mupinensis)和黑顶噪鹛(Trochalopteron affine)为保护区新记录种,而大熊猫(Ailuropoda melanoleuca)为汶川地震后首次拍到。兽类中,花面狸(Paguma larvata)、黄喉貂(Martes flavigula)和中华斑羚(Naemorhedus griseus)3种动物的独立有效照片总数占全部兽类独立有效照片数的50.2%。鸟类中,血雉(Ithaginis cruentus)和红腹角雉(Tragopan temminckii)的独立有效照片总数占全部鸟类独立有效照片数的91.6%。本研究为白水河国家级自然保护区野生动物资源管理和保护提供了参考依据。

From May 2017 to May 2018, we used camera traps to investigate the ground-dwelling bird and mammal species in the Sichuan Baishuihe National Nature Reserve, China. From footage of over 3,832 camera trap days from 24 camera trap stations, we identified 535 independent wildlife images, including 17 mammal species belonging to 10 families and 4 orders and 10 bird species belonging to 4 families and 2 orders. Five of these species are listed as Class Ⅰ Nationally Protected Wildlife, and 8 species are listed as Class Ⅱ. Hystrix hodgsoni, Turdus mupinensis and Trochalopteron affine were newly recorded in the nature reserve, and Ailuropoda melanoleuca was first recorded after the 2008 Wenchuan Earthquake. For mammals, the number of independent images of Paguma larvata, Martes flavigula and Naemorhedus griseus accounted for 50.2%, and for birds, that of Ithaginis cruentus and Tragopan temminckii accounted for 91.6%. Our study provides important baseline information for the management and conservation of wildlife in the Baishuihe National Nature Reserve.
