Reveals the radial incremental dynamics of predominant species (Scots pine Pinus sylvestris, Norway spruce Picea abies and black alder Alnus glutinosa) in various types of moist forests: establishes master chronology for these species in boggy soils of the Lithuanian SSR; assesses the meteorological factors which significantly impact on the radial increment of trees in boggy soils; and attempts to forecast, for at last 20 yr, the ecological background of forest growth
