| Zusammenfassung |
| Raising safety levees and reinforcing dykes is not a sufficient and
sustainable solution to the intense winter and summer floods occurring with
increasing frequency in Eastern Europe. An alternative, creating permanently
flooded floodplain wetlands, requires improved understanding of ecological
consequences. A 9 month mesocosm study (starting in January), under natural
light and temperature conditions, was initiated to understand the role of
previous land use (fertility intensity) and flooding water quality on soil
biogeochemistry and vegetation development. Flooding resulted in severe
eutrophication of both sediment pore water and surface water, particularly
for more fertilized soil and sulphate pollution. Vegetation development was
mainly determined by soil quality, resulting in a strong decline of most
species from the highly fertilized location, especially in combination with
higher nitrate and sulphate concentrations. Soils from the less fertilized
location showed, in contrast, luxurious growth of target Carex species regardless
water quality. The observed interacting effects of water quality and
agricultural use are important in assessing the consequences of planned
measures for ecosystem functioning and biodiversity in river floodplains. |
