“…In alignment with the preceding research, we acknowledged that environmental factors such as livestock grazing, road, bamboo distribution, and topography influence giant panda habitat selection (Bai et al, 2020;Hu et al, 1985;Ouyang et al, 2001). The Pearson correlation coefficient matrix was used to exclude highly correlated factors to prevent excessive collinearity (|r| ≥0.85).…”

As human activities continue to expand, wildlife persistence faces escalating threats from roads. In Wolong area of Giant Panda National Park, the local giant pandas (Ailuropoda melanoleuca) are divided into two population groups along the National Highway G350 (NHG). Therefore, selecting suitable areas to help those giant pandas communicate across the NHG is necessary. In this research, we evaluated the presence of human activities and simulated their absence to analyze how they affect the giant panda's habitat in Wolong. Subsequently, based on the kernel density estimation (KDE) for giant pandas and the main human distribution locations, we selected suitable areas for the population link between the two road sections on the NHG. We simulated the absence of human activities on the two road sections to compare changes in the habitat suitability index (HSI) and connectivity value (CV) relative to their presence. We aimed to carefully select the area for future giant panda corridor plans and simulate whether eliminating human activities will significantly improve the HSI and CV of the area. Our results show that: (1) Human activities presence has led to subtle changes in the landscape pattern of suitable habitats and a decrease in Wolong by 78.76 km2 compared to their absence. (2) Human activities presence significantly reduced HSI and CV in the 1000 m buffer along the NHG compared to their absence. (3) The HSI and CV of the 1000 m buffer in the simulated absence of human activities for the two road sections were significantly higher than their presence. This research identified the optimal road section for crossing the NHG to link giant panda population groups and habitats in Wolong. These insights are significant for formulating conservation decisions and corridor plans and for promoting wildlife conservation in reserves amid high levels of human activity.

“…According to existing studies, giant pandas usually choose old growth or secondary forests with medium to high densities of bamboo, medium altitudes and gentle slopes, and usually choose to avoid human disturbance and livestock [20][21][22][23]. In addition, forest age, topography, and the presence of bamboo were key predictor variables determining habitat selection by giant pandas at different scales [24,25].…”

The giant panda (Ailuropoda melanoleuca) is the flagship species of animal conservation worldwide, and the number of captive pandas reached 673 in 2021. According to the Fourth National Survey Report on the Giant Panda, there are 1864 wild pandas, segregated into 33 local populations, and 25 of these populations are too small to be self-sustaining. In addition to the conservation and restoration of panda habitats, conservation translocations, an approach that has been shown to be effective in slowing or reversing biodiversity loss, are highly desirable for panda conservation. The captive-bred panda population has grown rapidly, laying the foundation for releasing captive-bred pandas into the wild. This paper reviews the scientific advances in conservation translocations of pandas. Studies have shown that before translocation conservation programs are implemented, we should determine what factors are causing the depletion of the original population at the release site. The selection of suitable release sites and individuals will help to improve the survival rate of released individuals in the wild. Pre-release training and post-release monitoring are essential to ensure successful releases. We also see the great potential for increasing applications of Adaptive Management to improve the success of giant panda conservation translocation programs. This review provides theoretical guidance for improvement of the success rate in conservation translocations for captive pandas, and uses the panda as a model species to provide a global reference for the conservation translocations of rare and endangered species.

“…Secondary forests that have regrown after logging can, in some conditions, be suitable habitat for pandas (Ouyang et al 2002;Bearer et al 2008;Duan et al 2014). In the Sichuan Wolong Nature Reserve, it takes approximately equal to 50 years for the secondary forest to become suitable habitat for pandas and approximately equal to 70-80 years for the vegetation community structure to resemble that of the native forest (Ouyang et al 2002). Another study at the same reserve indicated that at least 37 years of natural recovery time was needed for pandas to begin to reuse the land (Bearer et al 2008).…”

Giant panda habitat restoration requires more than just planting bamboo and trees

Planting bamboo and trees is of great importance in giant panda (Ailuropoda melanoleuca) habitat restoration. In practice, however, simply planting bamboo and trees cannot effectively and rapidly restore lost, degraded, and fragmented habitats. Based on present restoration work in the Qinling Mountains, China, we argue that: (1) Planting should be done on open and suitable forest lands, but the area that could be afforested is relatively small. (2) Forests that have regrown naturally on cut-over lands are mostly middle-aged and early secondary stands, which need to be managed, not replanted. (3) Plantations of nonnative larch (Larix spp.) urgently need to be replaced and replanted with native trees and bamboos, but new policies are needed that allow these plantations to be thinned or cut. (4) Bamboo forests in the mid-high mountain zones need to be assessed to determine if they are disclimaxes of degraded forests. Pilot studies are needed to determine the best need and practices to rehabilitate and restore them. We conclude that the restoration of panda habitat cannot be accomplished simply through tree and bamboo plantings.
