Assessment of effective conservation of the sichuan takin by giant panda reserves through functional zoning

The flagship species conservation strategy is widely practiced in nature reserves. However, few studies have quantitatively explored whether the current functional zoning adequately conserves the habitats of other species. To examine this problem, we selected the Tangjiahe, Xuebaoding, and Wanglang national nature reserves in southwest China and tested the protective efficiency of the giant panda (Ailuropoda melanoleuca David, 1869) reserves on a local herbivore-Sichuan takin (Budorcas taxicolor tibetana Hodgson, 1850) in functional zoning. We predicted that the habitat distribution of the Sichuan takin with Maxent and habitat suitability would be classified as very low, low, moderately, or highly suitable. We calculated the percentage of each type of habitat class across the core, buffer, and experimental zones in these reserves and introduced an economic index-present value index to further assess the efficacy of the functional zoning in conserving the habitat of Sichuan takin. Our findings indicate that suitable habitat distributions of Sichuan takin are multicore and influenced by diverse variables in different nature reserves. The percentage of moderately suitable and highly suitable habitat in the core zone is 69% and 54% in Tangjiahe, 76% and 75% in Wanglang, and 47% and 28% in Xuebaoding, respectively. The present value index of moderately and highly suitable habitat is 1.01 and 0.79 (Tangjiahe), 0.87 and 0.86 (Wanglang), 0.76 and 0.44 (Xuebaoding), respectively. The efficiency of functional zoning on Sichuan takin seems lower than imagined in giant panda reserves, and species that have important impacts on local ecosystem need further estimation and greater focus.
