“…However, panda conservation is still under pressure, particularly due to habitat loss and fragmentation [ 5 ], which greatly increases the risk of small and isolated panda populations becoming extinct [ 6 ]. In addition, the Chinese government has implemented a new round of collective forest reforms, in which 24% of forest ownership was transferred to residents within the habitat of the giant panda in Sichuan Province.…”

Simple SummaryThis study evaluates the effect of local, regional, and global factors on the recovery of giant panda populations and their habitat, questioning the recent downgrading in the conservation status of this iconic species. We highlight the actions taken over the last decade, which were primarily local scale changes and efforts for protecting pandas. Broader regional development and global climate change are expected to negatively affect current population trends in the long-term; this phenomenon has been documented in other wildlife populations also showing a recent recovery. Thus, we call for a revision of the assessments stipulated by the International Union for Conservation of Nature to incorporate broader potential impacts in predicting the future survival of threatened populations, thereby, ensuring that appropriate and objective protection measures are implemented well in advance.AbstractThe International Union for Conservation of Nature (IUCN) reduced the threat status of the giant panda from “endangered” to “vulnerable” in September 2016. In this study, we analyzed current practices for giant panda conservation at regional and local environmental scales, based on recent reports of giant panda protection efforts in Sichuan Province, China, combined with the survey results from 927 households within and adjacent to the giant panda reserves in this area. The results showed that household attitudes were very positive regarding giant panda protection efforts. Over the last 10 years, farmers’ dependence on the natural resources provided by giant panda reserves significantly decreased. However, socio-economic development increased resource consumption, and led to climate change, habitat fragmentation, environmental pollution, and other issues that placed increased pressure on giant panda populations. This difference between local and regional scales must be considered when evaluating the IUCN status of giant pandas. While the status of this species has improved in the short-term due to positive local attitudes, large-scale socio-economic development pressure could have long-term negative impacts. Consequently, the IUCN assessment leading to the classification of giant panda as “vulnerable” instead of “endangered”, should not affect its conservation intensity and effort, as such actions could negatively impact population recovery efforts, leading to the extinction of this charismatic species.

“…In recent years, due to the ecological effects of local construction and development, such as the locations of manufacturing industries, the construction of dams and highways, as well as the development of tourism, habitats have been increasingly separated into isolated patches. Thus, realistic models should include dispersal processes that take into consideration the effects of spatial heterogeneity [11,16,18,19,[29][30][31]33]. In [30], Takeuchi considered the following integer-order single-species system:…”

In this paper, we consider a fractional-order single-species model, which is composed of several patches connected by diffusion. We first prove the existence, uniqueness, non-negativity, and boundedness of solutions for the model, as desired in any population dynamics. Moreover, we also obtain some sufficient conditions ensuring the existence and uniform asymptotic stability of the positive equilibrium point for the investigated system. Finally, numerical simulations are presented to demonstrate the validity and feasibility of the theoretical results.
