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).
