(1967): In 1956-1962 investigations of swamps from the forest-steppe and steppe of Ukraine were carried out. They were followed by spore-pollen studies of swamp deposits. These materials are partially published in papers devoted to the history of vegetation in the south of Ukraine and re-vegetation of landscape in different phases of Holocene (Artyushenko, Bachurina, 1958; Artyushenko, 1959, 1960; Artyushenko, Kucheryava, 1964). Peat area in the investigated region is very small. In the forest-steppe peat occupies 1.1%, and in the steppe - 0.03% of the whole area (Peat Reserve of the Ukrainian SSR, 1959).
