The knowledge of carbon (C) stock and its dynamics is crucial for understanding the role of grassland ecosystems in Hindu Kush Himalayan (HKH) terrestrial C cycle. To date, a comprehensive assessment on C balance in HKH’s grasslands is still lacking. By reviewing published literature, this study aims to evaluate soil organic carbon (SOC) stock in HKH’s grasslands. Our results are summarized as follows: (1) SOC density varied greatly between 1.6 and 11.7 kg C m-2. (2) The magnitude of SOC in Grassland ecosystems in different countries of HKH region differed greatly. (3) Spatial patterns of grassland SOC were closely correlated with climate and topography. Human activities, such as livestock grazing and fencing could also affect soil C dynamics in HKH’s grasslands.
