Sicista concolor

The Chinese scissorium belongs to the subfamily Sicidinae of the family Jerboa. There are 13 species in the subfamily worldwide, 4 of which are in China. The Chinese scissorium is the southernmost species in the distribution area and one of the two species that live in the forest. The status of this species is stable and undisputed. Although the distribution area is wide, the population is not large and it is a relatively rare rodent.

The Chinese rat is endemic to my country and is only found in a few areas of Qinghai, Gansu, Sichuan, Yunnan and Shaanxi. Habitat and habits It lives in mixed coniferous and broad-leaved grass at 3000-4000m. It is active at night and good at climbing. It feeds on stems, leaves, buds and seeds of plants, and also eats insects. It reproduces once a year and produces 3-6 pups.

From the time this species was named to the present century, it has only been found in a few areas of my country. More than 20 specimens have been collected in the past 40 years. It is a very rare species. Due to its small number, little is known about the biology of this species, and relevant information is very scarce. It is estimated that if its habitat is not destroyed, its survival should not be seriously threatened.

Distributed in Sichuan, Yunnan, Gansu and Shaanxi, it is a forest and forest edge shrub species at high altitudes (2500m).
