Machar Department of Biology Faculty of Education Palacký University in Olomouc Olomouc Czech Republic ABSTRACT At present the coppice-with-standards system has become so rare in floodplain forests that it is considered a natural monument. In 1990 the coppice-with-standards system was not recorded in the territory of the Czech Republic. This state contradicts the increasing interest of nature protection organizations in the relict remainders of the coppice-with-standards system which is to be considered the closest to naturally preserved lowland forest type and is therefore recommended as the final state of the biocentres and biocorridors in today s floodplain forests. The aim of this paper is to present the results of the inventory dealing with the present occurrence of the coppice-with-standards system in the floodplain forest of the Litovelské Pomoraví Protected Landscape Area PLA in a historical context. Keywords coppice-with-standards floodplain forest forest management storeyed high forest The floodplain landscape belongs to the youngest geological geomorphological and landscape formation in Europe. Both the origin and the development of floodplain landscapes in Central Europe have been the subject of a long-term study for an overview see . Rulf 1994 . During the prehistoric period and the Middle Ages the floodplain landscape was subjected to extensive settlement and served simultaneously as an important communication and migration space see Opravil 1983 Polacek 1999 leaving no doubt that humans had an essential influence on the formation of floodplains in Europe Rybnicek 2001 . The natural ecosystems of Central European floodplains which were predominantly covered by floodplain forests were very strongly influenced by humans during the whole of the Holocene. The anthropogenic conditionality of the formation and development of .
