Sichuan Grasshopper-warbler Locustella chengi


Justification of Red List Category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (extent of occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Distribution and population

Locustella chengi is endemic as a breeder to China, found only in Sichuan, Guizhou, Hubei, Hunan and Shaanxi, and potentially in Jiangxi. It is presumed to be a migrant, but the wintering grounds are as yet unknown.


Found on slopes as well as on flat ground, in open habitats with dense low vegetation of herbs and/or ferns, often in association with trees, such as in forest clearings and in sparse secondary forest. The species has also been oinside tea plantations.
