Vegetation and soil at the terraces of the Dřevnice and theMorava rivers after flood
2008
The flood changed the character of observed flooding terraces
in the catchment area of the Dřevnice river and in an adjacent
part of the Morava river in July 1997. The changes of the
vegetation cover, selected soil parameters, and soil
contamination were investigated before and after the flood.
Changes of the vegetation cover were more perceptible in man
made modified part of the catchment area. Response of
aboveground plant biomass to the flood was of various
characters and took different time in dependence on the height
of water column, duration of flood, height of sediment and its
structure. Inundation promoted propagation of both ruderal (R
and CR strategists) and invasive species. However, many
competitive plant species (C strategists) were promoted by
floods, too. Ruderal plants appeared mostly one year after
flood, while new invasive plants appeared often already three
months after the flood. Almost all of vegetation changes have a
reverse character in the investigated area. The changes of the
soil properties were not evidently connected with changes of
the plant communities. However, the significant increase of the
heavy metals and PAHs contamination in the soils were observed.
