湖南省南岳衡山国家级自然保护区鸟兽多样性OACSTPCD

A survey was conducted on birds and mammals in Nanyue Hengshan National Nature Reserve,Hunan Province from August 2022 to September 2023.According to the Guide to National Bird and Mam-mal Diversity Survey,the sampling method was used for birds and the infrared camera survey method was used for mammals.A total of 30 transect lines were completed and 15 infrared cameras were deployed.Based on field survey data and references,totally 148 bird species were recorded,belonging to 14 orders and 48 families,while 24 mammalian species were recorded,belonging to 5 orders and 14 families.Among them,there were 3 class Ⅰ nationally protected species and 32 class Ⅱ nationally protected species.Among birds,there were 14 eurytopic species(9.46％),85 Oriental realm species(57.43％)and 49 Palaearctic realm species(33.11％),and there were 36 summer visitors(24.32％),80 residents(54.05％),29 winter visitors(19.59％),and 19 passage migrants(12.84％).Among mammals,there were 16 Oriental realm species(66.67％),3 Pa-laearctic realm species(12.50％),and 5 widespread species(20.83％).According to the G-F index,bird di-versity was relatively abundant at both the family and genus levels(DF=21.37,DG=3.80,DG-F=0.822),but mam-mal diversity at the family and genus levels was relatively low(DF=5.87,DG=2.65,DG-F=0.549).This study con-ducted a background investigation on bird and mammal resources in the protected area and its surroundings,aiming to supplement basic data and provide guidance and suggestions for protection of species diversity.
