A preliminary survey on giant pandas and their sympatric species in Chongzhou area of Giant Panda National Park(outside the original nature reserve)
From September 2021 to June 2022,a survey was carried out in Chongzhou area of Giant Panda National Park and outside the original Anzihe Nature Reserve by the line transect survey method and infrared camera technology.A total of 47 survey transects were completed,47 infrared cameras were installed,and 24,101 infrared camera image data and 608 independent effective recordings were obtained in a total of 8543 effective camera working days.A total of 24 wild mammal species belonging to 12 families and 4 orders and 17 bird species belonging to 8 families and 4 orders were identified.Among the detected species,3 species were the class Ⅰ nationally protected wild animals and 16 species were the class Ⅱ nationally protected wild animals.Two species was rated as Endangered(EN),six as Vulnerable(VU)and threee as Near Threatened(NT)by IUCN.The Rhesus Macaque(Macaca mulatta)was photographed as the first infrared camera image in Chongzhou City,and the Spotted Linsang(Prionodon pardicolor)was investigated as the first distribution record in Chongzhou City.In this study,6 faecal traces of giant panda(Ailuropoda melanoleuca)were found on 5 translines,and the giant panda images were photographed at 7 camera sites in 6 survey grids(2 km×2 km).The transline encounter rate was 10.64％,the relative abundance index(RAI)was 0.18,and the overall grid share was 17.02％,mainly distributed in mixed forests and bamboo forests at the altitude of 1800～2400 m.The results indicated that the transversal encounter rate,relative abundance index(RAI)and grid occupancy of Wild Boar(Sus scrofa),Tufted Deer(Elaphodus cephalophus)and Sambar Deer(Rusa unicolor)all ranked in the forefront,and there were various kinds of mammals and bird species distribution in different functional zones.Sympatric species of Giant panda were mainly distributed in mixed forest habitats in mountainside(above 1 100 m altitude)and above areas,mainly concentrated in the area near the original Anzihe Nature Reserve,and relatively few in Jiulonggou area.The results of this study can provide scientific support for the optimization and adjustment of subsequent targeted protection and management strategies in Chongzhou area of Giant Panda National Park.
