Preliminary study on the diversity of medium and large-sized mammals and pheasants at Chuxiong sub-region,Yunnan Ailaoshan National Na-ture Reserve
Between March 2020 and May 2022,we conducted a systematic camera-trapping survey to understand the di-versity of medium and large-sized mammals and pheasants at Chuxiong Prefecture sub-region of Yunnan Ailaoshan Na-tional Nature Reserve.We set 153 camera traps along 1 km ×1 km grids,with a total trapping effort of 59 623 days,which yielded 9 309 independent records of wildlife species.A total of 23 medium and large-sized terrestrial mammals and seven pheasant species were observed:14 families of 5 orders for mammals and 1 family of 1 order for pheasants.Of which,three and 14 species were listed as Class One and Class Two protected species respectively by the Chinese Wildlife Conservation Law.The five species with the highest relative abundance indices(RAI)were the northern red muntjac(Muntiacus vaginalis,RAI=7.52),tufted deer(Elaphodus cephalophus,RAI=2.43),wild boar(Sus scrofa,RAI=2.39),macaque(Macaca mulatta,RAI=2.26)and Malayan porcupine(Hystrix brachyura,RAI=2.16).Spe-cies rank-abundance curve showed that species in the first three ranks were the northern red muntjac,wild boar,and sil-ver pheasant Lophura nycthemera,which together contributed to 65％of the accumulative abundance of the whole com-munity.In addition,our camera-trapping survey recorded numerous human-related inerference such as livestock grazing,indicating that the reserve is under some levels of anthropogenic disturbance.Overall,our first systematic camera-trap-ping survey provides basic information on the diversity of medium and large-sized mammals and pheasants at Chuxiong Prefecture sub-region of Yunnan Ailaoshan National Nature Reserve.Such knowledge is important for local wildlife bio-diversity management and conservation.
