摘　　要：The Asian elephant(Elephas maximus),an endangered species on the International Union for Conservation of Nature Red List,is the largest terrestrial animal living in Asia.They require a relatively large space to live in.In China,the wild Asian elephants exist only in XiShuangBanNa,Pu’Er,and LinCang of southern Yunnan Province,with 95%of the wild population residing in the XiShuangBanNa National Nature Reserve.In recent years,territorial conflicts have arisen between humans and elephants around the national nature reserve.A herd of wild Asian elephants roamed north,venturing over 500 km from the largest area of the reserve,MengYang(998 km^(2),600–1,500 m above sea level[ASL]in altitude),in March of 2020 to KunMing(the capital of Yunnan Province,ca.2000 m ASL in altitude)in early June 2021(Figure 1A).These elephants,traipsing north through fields,highways,villages,and towns,have stepped into the international spotlight,not only because such long-distance migration never happened in the past half a century but also because the United Nations Biodiversity Conference will be held in KunMing in the coming October.However,no one knows exactly why this has happened,as elephant migration,a complex ecological process,can be of varied duration,distance,timing,and driver.
