Yunnan has less than 4% of the land of China, yet the province harbors around 42.6% of all protected plant species and 72.5% of all protected wild animals in the country, of which 15% are strictly endemic to Yunnan.[47] Yunnan is home to, most notably, the southeast Asian gaur, a giant forest-dwelling bovine, the Indochinese tiger and the Asian elephant.[48] Other extremely rare species are the Yunnan box turtle[49] and the Yunnan snub-nosed monkey.[50] It is feared that the Yunnan lar gibbon, another moribund species, has already gone extinct.[51] Yunnan province has 11 national and regional nature reserves.
