基于红外相机技术的湖南小溪国家级自然保护区鸟类和兽类资源的初步调查
Preliminary Investigation of Avian and Mammalian Resources in Xiaoxi National Nature Reserve,Hunan Province,Based on Camera Trapping
摘要
Abstract
From July 2022 to May 2024,a preliminary investigation of birds and mammals in the Xiaoxi National Nature Reserve in Hunan was conducted using infrared camera traps.A total of 118 camera trap-pings(UVL4)were deployed,with an effective camera operation period of 25 731 days,yielding 6 774 inde-pendent valid photos.The survey recorded 31 species of birds(Aves)across 7 orders and 17 families,and 17 species of mammals(Mammalia)across 5 orders and 10 families.Among them,there were 2 species of first-class nationally protected wildlife,Syrmaticus ellioti and Viverricula indica;and 10 species of second-class nationally protected wildlife,such as Chrysolophus pictus,Macaca mulatta and Elaphodus cephalophus.The mammals with relatively high relative abundance indices(RAI)were A rctonyx collaris(IRa=6.7 16),Paguma lar-vata(IRA=4.694)and Sus scrofa(IRA=2.099),and the bird species were Zoothera aurea(IRA=0.688),Syrmaticus ellioti(IRA=0.536)and Chrysolophus pictus(IRA=0.412).The species accumulation curve indicated that the curve for mammals tended to flatten into an asymptote with around 20 camera traps deployed,suggesting a rela-tively accurate estimation of mammal species richness.In contrast,the curve for birds continued to show an upward trend even after all 118 camera traps were installed.Furthermore,the majority of the records were ground-foraging songbirds,indicating that the current intensity of infrared camera monitoring was insuffi-cient to grasp the actual species richness of the bird community.This study provides baseline data for the continuous monitoring and assessment of wildlife diversity in the Xiaoxi National Nature Reserve.关键词
