Abstract:

In order to document the wildlife resources in Guangxi Encheng National Nature Reserve. We set up 58 infrared camera traps in this natural reserve to monitor mammals and forest birds from December 2019 to January 2021. The surveys produced a total of 17 332 camera-days of data, and 6 680 independent wildlife photographs were collected. We identified 20 mammal species belonging to 5 orders and 13 families, as well as 61 bird species belonging to 9 orders and 20 families. Among the detected species, one species is listed as first-class National Protected Wildlife: Fran?ois’s Langur (Trachypithecus francoisi), and 26 species (6 mammal species and 20 bird species) are listed as second-class National Protected Wildlife. There are 2 species are classified as Endangered (EN), 6 as Vulnerable (VU) and 19 as Near Threatened (NT) according to the Red List of China’s Vertebrates. Based on the relative abundance index, the mammal with the highest relative abundance index was Leopoldamys edwardsi, the bird was Lophura nycthemera. Camera traps technique is an effective method for wildlife survey. Our results provided the primary records on the species composition and relative abundance of mammals and birds in the Guangxi Encheng National Nature Reserve. These will provide the basic information for future investigation of wildlife and management in the reserve.

摘要：

2019年12月—2021年1月，利用红外相机技术在广西恩城国家级自然保护区内布设了58个红外相机监测位点，对保护区内的兽类及地栖性鸟类多样性开展监测。本次监测共完成17 332个相机工作日，累计获得独立有效照片6 680张。共鉴定出兽类5目13科20种，鸟类9目20科61种，其中黑叶猴 (Trachypithecus francoisi) 为国家一级重点保护野生动物，26种为国家二级重点保护野生动物。被中国脊椎动物红色名录评估为濒危 (EN) 的有2种，易危 (VU) 6种，近危 (NT) 19种。物种相对多度指数 (RAI) 最高的兽类是小泡巨鼠 (Leopoldamys edwardsi)，鸟类是白鹇 (Lophura nycthemera)。本次监测初步掌握了广西恩城国家级自然保护区内的兽类及地栖性鸟类的种类组成和相对多度指数，为后续开展野生动物研究与保护管理工作提供基础资料。
