A contribution to diversity and importance of lines communities (ecotones) in cultural landscape
 Lacina, Jan
Detailed record
The ten-year development of vegetation cover of the Bečva river flood channel with special regard to ecotones
 Lacina, Jan
During the disastrous flood in July 1997 the Bečva river created notable flood channels, which are considerably more complex and wider than the previous technically designed one. In the fall of the vegetation period in 1997 the six most interesting segments between towns Valašské Mežiříčí and Přerov were chosen and left in further natural development. During 10 years the processes of spontaneous succession have been examined by means of repeated phytosociological records on the investigative transects which have been located on various habitats. Dynamic development of river channel and its vegetation communities (from grassy-herbal heath to flood-plain forest and its ecotones) differentiated by hydrologic conditions, topography and grain-size distribution is very notable on the transect near Osek nad Bečvou. It is indisputable that the high-magnitude flood revitalizated the riverine landscape, diversified its character and contributed to the higher biodiverisity.
