Habitat characteristics and potential distribution of Takin(Budorcas taxicolor)in Baishuijiang National Nature Reserve
Takin(Budorcas taxicolor)is a national first-class protected wild animal,and assessing its habitat is essential for the scientific conservation of this species.Taking Baishuijiang National Nature Re-serve as a case study,we conducted surveys of Takin trace points using transect methods,recording the habitat characteristics of these points.The Maximum Entropy(MaxEnt)model was utilized to assess and predict the habitat suitability for Takin within the reserve.The results indicate that suitable Takin habitats are primarily distributed around the Jiangshui River,Liujia Ping,and Danbu River protection stations,covering a total area of 634.33km2,accounting for 34.51％of the reserve's total area and 70.36％of the core area.The employed biogeographical model is reliable(AUC＞0.80).Among the six environmental variables considered,the annual mean temperature contributes the most,followed by annual precipitation,and then slope.The minimum altitude of Takin ecological source areas in the Baishuijiang Reserve is 1600 m,reaching a maximum of 3300 m.It is imperative to strengthen disturbance control,management,and monitoring in this region to mitigate further human-induced pressure on this ecological source area.
