Relationship between human disturbance and Endangered giant panda Ailuropoda melanoleuca habitat use in the Daxiangling Mountains

The Endangered giant panda Ailuropoda melanoleuca is one of the most threatened mammals. The species has experienced declines in its population and habitat as a result of human disturbance. We investigated the influence of human disturbance on habitat use by giant pandas in the Daxiangling Mountains, in China's Sichuan Province. We mapped all signs of giant panda and all locations of seven types of human disturbance in the study area. We used correlation analysis, generalized linear models, and Akaike information criteria to analyse the influence of the various types of human disturbances on habitat use by the giant panda. Our results showed that habitat use was positively correlated with elevation and distance from roads, residences, hydropower stations and logging or tree-felling sites, but negatively correlated with distance from bamboo shoot collection sites and trap sites. We found that the road-effect zone spanned a distance of c. 1,200 m and that human residence could affect the intensity of habitat use by giant pandas at distances > 2,500 m. The effect of roads on habitat use was probably influenced by the association of roads with residences, hydropower stations and mines. In the area occupied by giant pandas, we recommend increased regulation to minimize the expansion and impact of roads, residences, hydropower stations and logging activities.
