Abstract: Camera-trapping technology has become an important means of monitoring large and medium-sized mammals and understory birds, and is widely used in biodiversity survey. From 2018 to 2019, 56 infrared camera monitoring sites (one camera per hectare) were set up in Liziping National Nature Reserve using infrared camera monitoring technology to monitor wild mammals and birds in evergreen and deciduous broad-leaved mixed forests. All cameras had been working for a total of 17,074 effective working days, and a total of 15,746 independent and effective photos of wild animals had been obtained. 18 species of mammals belonging to 4 orders, 13 families and 16 species of birds belonging to 2 orders, 6 families had been identified. The first three species of mammals and three species of birds with high relative abundance index were tufted deer (Elaphodus cephalophus), Tibetan chief monkey (Macaca thibetana), the wild boar (Sus scrofa) and the blood pheasant (Ithaginis cruentus), red-bellied pheasant (Tragopan temminckii) and White-bellied Pheasant (Chrysolophus amherstiae) respectively. Two kinds of National I-level and 9 National-level II key protected species were recorded, and one species was evaluated as endangered (EN), five species as vulnerable (VU) and two species as near-endangered (NT) by IUCN Red List. In addition, infrared cameras have also monitored domestic animal activities (cattle, dogs, and horses) and human activities. It is recommended that management departments of the protected areas still need to take corresponding management measures to further enhance the protection awareness of surrounding residents and promote the coordinated development of the protected areas and the communities.
