The economics of growing downy birch stands on drained peatlands in Finland

[摘要] The aim of this study was to determine under what conditions and with what premises the growing ofEhrh. is an economically competitive alternative to the growing of Scots pine ( L.) in drained peatlands. The basic material consisted of all drainage projects in Ostrobothnia in Western Finland in 1937–38 and 1957–59, according to the archives of the Central Board of Forestry Tapio, including such areas that were at least moderately fertile and had birch dominated young stands or no tree cover. A total of 202 sample plots were measured.Betula pubescensPinus sylvestrisB. pubescensB. pubescens
