Abstract: Gaoligong Mountain National Nature Reserve is one of the world's biodiversity hotspots. To assess the current status of bird and mammal diversity on the western slope of Gaoligong Mountain, 52 infrared cameras were deployed within the jurisdiction of the Dahaoping station from December 2024 to September 2025 to conduct wildlife monitoring. During the monitoring period, a total of 1,728 independent valid photographs were obtained, identifying 23 wild mammal species (6 orders, 14 families) and 14 wild bird species (4 orders, 6 families). Among these, three species are listed as Class I nationally protected wildlife: Small Indian Civet, Mrs. Hume's Pheasant, and Cabot's Tragopan. 21 species are classified as Class II nationally protected wildlife, including the Tufted Deer, Red Muntjac, Yellow-throated Marten, Stump-tailed Macaque, and Chinese Serow. Analysis of relative abundance indicates that the Tufted Deer is the dominant species among mammals, while the Silver Pheasant is the dominant species among birds. Analysis of activity rhythms reveals that the peak activity periods for Tufted Deer, Red Muntjac and Wild Boar all occur between 6: 00 PM and 7: 00 PM. Silver Pheasant, Common Hill Partridge, and Temminck's Tragopan are all diurnal species, with peak activity periods occurring between 7: 00 AM and 8: 00 AM and between 6: 00 PM and 7:00 PM; the activity frequency of most bird and mammalian species exhibits a typical unimodal distribution pattern with altitude and temperature. The findings from this data analysis provide a theoretical foundation for formulating conservation measures to safeguard biodiversity within the protected area.
