摘要:

2017年4月至2019年10月, 利用红外相机在四川雪宝顶国家级自然保护区开展了野生动物调查工作。共在152个位点上布设了红外相机, 累积30,792个相机日, 共获得独立照片6,316张。共鉴定出野生动物105种, 包括27种兽类(隶属于4目13科)和78种鸟类(隶属于5目20科)。其中, 属于国家Ⅰ级重点保护的野生动物有7种, 分别是川金丝猴(Rhinopithecus roxellana)、大熊猫(Ailuropoda melanoleuca)、林麝(Moschus berezovskii)、四川羚牛(Budorcas tibetanus)、红喉雉鹑(Tetraophasis obscurus)、绿尾虹雉(Lophophorus lhuysii)和金雕(Aquila chrysaetos); 属于国家II级重点保护的野生动物有11种, 包括藏酋猴(Macaca thibetana)、藏雪鸡(Tetraogallus tibetanus)等。分析结果显示, 拍摄率最高的前5种兽类依次是中华斑羚(Naemorhedus griseus)、岩羊(Pseudois nayaur)、岩松鼠(Sciurotamias davidianus)、野猪(Sus scrofa)和猪獾(Arctonyx collaris); 拍摄率最高的前5种鸟类依次是血雉(Ithaginis cruentus)、雪鹑(Lerwa lerwa)、藏雪鸡(Tetraogallus tibetanus)、红腹角雉(Tragopan temminckii)和绿尾虹雉。此外, 红外相机还在26个位点上拍摄到了家畜, 在22个位点上拍摄到了人为活动。

Abstract

Aim: To investigate the diversity and spatial distribution of mammals and birds in Xuebaoding National Nature Reserve, camera traps were set up in the reserve from April 2017 to October 2018 and from April 2019 to October 2019.

Methods: The reserve was divided into 1-km2blocks within a Geographic Information System. Blocks were set up according to habitat type, and each habitat type had a camera. However, some cameras were moved to adjacent blocks due to poor location and other reasons six months after initial placement. A total of 195 camera traps were set up in 152 sites within 123 blocks.

Results: A total of 6,316 independent images were obtained over 30,792 camera-trapping days. Among them, 105 species were identified from camera trap images, including 27 mammal species belonging to 4 orders and 13 families, and 78 avian species belonging to 5 orders and 20 families. Among them, 7 species are listed in Class I national protected animals including Rhinopithecus roxellana, Ailuropoda melanoleuca, Moschus berezovskii, Budorcas tibetanus, Tetraophasis obscurus, Lophophorus lhuysii, and Aquila chrysaetos, while 12 species are listed as Class II national protected animals including Macaca thibetana, Tetraogallus tibetanus, etc. The results showed that the top five mammals with the highest photographic rate (PR) from high to low were Naemorhedus griseus, Pseudois nayaur, Sciurotamias davidianus, Sus scrofaand Arctonyx collaris. Additionally, the top five birds with the highest PR were Ithaginis cruentus, Lerwa lerwa, Tetraogallus tibetanus, Tragopan temminckiiand Lophophorus lhuysii. Additionally, livestock and human activities were recorded at 26 and 22 camera sites, respectively.

Conclusions: The results indicate that there is wide diversity of wild animals in Xuebaoding National Nature Reserve, along with diversity of rare and endangered animals. For example, giant pandas are abundant and widely distributed in the reserve. However, our results show that pandas and livestock spatially overlap in some areas. Consequently, we suggest the reserve should strengthen the control of grazing livestock and raise the protection awareness of surrounding residents through community publicity.
