Quantifying and managing carbon (C) storage in urban green space (UGS) soils is associatedwith the ecosystem services necessary for human well-being and the national C inventory report ofthe Intergovernmental Panel on Climate Change (IPCC). Here, the soil C stocks at 30-cm depths indifferent types of UGS's (roadside, park, school forest, and riverside) were studied in three majorSouth Korean cities that have experienced recent, rapid development. The total C of 666 soil sampleswas analyzed, and these results were combined with the available UGS inventory data. Overall,the mean soil bulk density, C concentration, and C density at 30-cm depths were 1.22 g·cm-3,7.31 g·C· kg-1, and 2.13 kg·C·m-2, respectively. The UGS soil C stock (Gg· C) at 30-cm depths was105.6 for Seoul, 43.6 for Daegu, and 26.4 for Daejeon. The lower C storage of Korean UGS soilsthan those of other countries is due to the low soil C concentration and the smaller land area underUGS. Strategic management practices that augment the organic matter supply in soil are expected toenhance C storage in South Korean UGS soils.
