Population justification: The global population is estimated to number > c.10,000 individuals (Ferguson-Lees and Christie 2001), while national population sizes have been estimated at c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in China and c.10,000-100,000 breeding pairs and c.1,000-10,000 individuals on migration in Russia (Brazil 2009).
Trend justification: The population is suspected to be in decline owing to habitat destruction through drainage of wetlands and agricultural expansion (Ferguson-Lees and Christie 2001). The breeding population in the Primorsky Krai region of Russia declined significantly in the second part of the 20th century, but is now gradually recovering due to an increase in the area of fallow land (Shokhrin et al. 2020). Ganesh and Prashanth (2018) recorded a decline in the total number of overwintering harriers of various species (including C. melanoleucos) at roost sites in India during 1985-2015.
