General description
Intensive anthropogenic use and alteration of riverine landscapes have led to severe degradation of river-floodplain systems, especially in highly industrialized countries. River bed erosion and loss of riparian habitat and species are among the most prominent consequences of these engineering works (Rohde et al. 2005).
The extensification of the land use at the adjacent areas of the river will lead to wider space for the development of riparian vegetation. The ability of restoration measures to host typical riparian species and to increase local plant diversity depends on the distance to near-natural stretches as the presence of a viable seed bank is an important prerequisite for the rehabilitation of natural vegetation. Passive restoration of riparian areas may be effective if invasive species do not compete with native vegetation (Roni et al. 2005).
Flood risk can be reduced through reduced runoff and increased soil water storage. Higher vegetation coverage and reduced surface flow often result in greater filtration of pollutants. Well managed meadows and pastures nearby the riparian buffers contribute to this effect by additionally reducing runoff, slowing surface flow and increasing infiltration (Kedziora et al. 2011). This would need to be coordinated at catchment scale.
Applicability
Species dispersal and establishment might be hampered by decisions taken outside the scope of the restoration project due to catchment influences (Rohde et al. 2005). It is important to ensure a coordinated riparian management effort along a catchment to achieve improvements in many chemical and ecological parameters of streams.
