A review of the impacts of four identified major human disturbances on the habitat and habitat use of wild giant pandas from 2015 to 2020.

Human disturbance poses a serious threat to the survival of the giant panda (Ailuropoda melanoleuca), but few systematic and specialized reviews on the impacts of human disturbance on pandas and their habitats have been published. After the fourth giant panda survey (2011-2014), some new studies and important findings have emerged. To update the understanding of the impacts of human disturbance, research on the impacts of major human disturbances on the habitat and habitat use of wild giant pandas from 2015 to 2020 was reviewed based on 33 publications (including three books and 30 articles). The major human disturbances in panda habitat included livestock grazing, roads, herb collection, and logging. Livestock affects panda habitat by occupying, disturbing, and defecating in it, and the time and intensity of habitat use by horses are greater than the time and intensity at which pandas use their habitats. Roads affect nearby habitats by disturbing the vegetation and causing pollution, and the effect of roads extends far beyond the roads themselves and varies with road type. The impacts of logging on the forest structure and bamboo in panda habitat are long-term. Pandas avoid habitats disturbed by livestock grazing, roads, and logging. The impacts of herb collection are not known, because they have received little attention. Findings suggested a need for further research on human disturbance to giant pandas, focusing on comprehensive evaluations of the interactions between different disturbances.
