General description

Isolated aquatic habitats at the Danube in Austria (source : BOKU, IHG)
Isolated aquatic habitats at the Danube in Austria (source : BOKU, IHG)

Long-term isolated floodplain water bodies in older successional stages probably contribute significantly to the overall aquatic biodiversity of large rivers (Schomaker & Wolter 2011). Floodplain restoration and management should account for variation in inundation frequencies and address the maintenance of infrequently connected floodplain waters, as is already considered in floodplain woodland management (Geerling et al. 2006).



Expected effect of measure on (including literature citations)

Floodplain water bodies in advanced successional stages provide most suitable habitats for still-water species and specialist species that have evolved physiological adaptations and strategies to survive hypoxic and anoxic conditions (Schomaker & Wolter 2011).
