With a data set of Eurasian forest litter fall based on 471 stands, annual litterfall was estimated to be 6.53 Pgdm a-1 (1 Pg = 1015 g; dm, dry matter) in Eurasian forests, of which more than half occurred in tropical and subtropical forests, and a third in the boreal area. With litterfall, around 2.94 Pg C per year is transferred from the forest vegetation to the soil on this continent.
