Abstract:

Objective: To investigate the status quo of large and medium-sized mammal diversity, reveal the spatial distribution pattern of species diversity in order to provide scientific basis for the protection of mammal resources in the Cangshan mountain.Methods: From July 2020 to December 2022, the current status of mammal diversity in Cangshan region was investigated by line transects, infrared automatic camera trap method, and interview method. Finally, 47 transect lines with total length of 52 km were

investigated, and 9 975 camera days from 60 infrared automatic cameras were implemented. Results: There were at least 19 species of large and medium-sized mammals distributed in the Cangshan mountain, including 9 species from first or second-class protection wildlife lists of China such as Moschus berezovskii and Ailurus styani, and the species richness of Carnivora and Cetartiodactyla was the highest. The mammal species diversity was decreased with the increase of altitude, and was related to the vegetation type. Conclusion:Large carnivora animals are vulnerable in biodiversity conservation, and the habitats of coniferous and broad-leaved mixed forest and broad-leaved forest at low altitude have higher value for the conservation of large and medium-sized mammals.
