Extinction-risk assessment of extant populations
Through the sampling method in GIS, we extracted the extinction probability of extant distribution sites according to the extinction-risk map of Chinese pangolin. The results showed that 48.77% of extant distribution sites were confronted with no extinction risk (extinction probability < 0.2), 25.93% were at low extinction risk [0.2, 0.36), 11.73% were at moderate extinction risk [0.36, 0.55) and 13.41% were at high extinction risk [0.55, 0.93) (Fig. 3, Fig. 5). In total, a quarter of extant populations were at notable (moderate and high) extinction risk. Those sites in moderate and high extinction risk were dispersedly distributed in southeast China, including Guangdong, Jiangxi, Zhejiang, Hunan, Fujian, Jiangsu Province and Taiwan (Fig. 5). Fifteen distribution sites were confronted with high extinction risk (total 41) spread over Guangdong Province, eight were in Jiangxi and Taiwan Provinces, and five were in Zhejiang Province (Fig. 5).
