| Description | 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. |
