‣ Monitoring results of revitalization measures on an urban lowland River(Liesingbach, Vienna, Austria)Projetc’s summary:The Liesingbach, flowing through the south of Vienna, Austria, is an urbanstream that has been designated as a heavily modified body mainly because the riverwas canalized, its bed was hard and the water quality poor due to considerablewastewater discharge. A study in 1999 before the restoration confirmed the poorecological status in terms of hydromorphology, aquatic biocoenosis, riparianvegetation and water related terrestrial fauna. Until 2005, a 5.5 Km long reach closeto the south-eastern city limit was revitalized with the intention to induce anecological development by improving the hydromorphological conditions. However,the creation of a typical lowland river morphology was limited due to the difficulties inacquiring adjoining premises. The implementation of the European Water FrameworkDirective into national legislation gave rise to an interdisciplinary assessment ofrealistic development objectives for an urban river like the Liesingbach.Consecutively, the Liesingbach was classified as a heavily modified water body.‣ River Wien restoration project: improvement of the ecological condition of aheavily modified river in a urban environment (Austria)Project summary:The Wien River has its source in the Vienna Woods, to the west of Vienna,Austria, at 620 m ASL. With a length of 32 Km and a catchments area of 230 sqKm,it is, beside the River Danube, the most important river passing through the city ofVienna. The catchments area mainly consists of flysch with a very low pore volumeand a low water retention capacity. Rainfall therefore leads to high surface runoff andan immediate and strong rise of the discharge of the Wien River. For flood protection,the river was placed in a deep channel in the late 19 th century and the river bottomwas sealed with paving stones and concrete.‣ LIFE Nature Project Wachau of dry grasslands and Danube nase (Austria)Projetc’s summary:In the LIFE Nature Project these particular habitats are maintained by removing bushes and mowing grass cover. Grazing with Waldschaf sheep preventsopen spaces from becoming overgrown. The focal areas for dry grassland65
management are in the communities of Dürnstein, Rossatz-Arnsdorf, Spitz andWeissenkirchen. The Arbeitskreis Wachau group cleared and recreated over 50hectares of overgrown dry grassland and meadow. Recurrent land managementprocedures were carried out on a further 100 acres.The LIFE Nature project, in collaboration with the municipality of Mautern, hastaken the semi-natural forest around the Ferdinand-Warte look-out point nearUnterbergern out of utilisation. Forest protection areas covering almost 160 hectareshave been established, in collaboration with the Rossatz agricultural association andthe communities in Rossatz-Arnsdorf and Spitz. These untreated areas form thehabitat for many endangered bird species such as the black stork, white-backedwoodpecker, red-breasted flycatcher and many more. Old and deadwood arenecessary for the survival of endangered beetles such as the Great Capricorn beetleand the stag beetle.‣ Lobau (Austria): reconnection at floodplainProjetc’s summary:The improved connectivity between water bodies at higher mean water levelsin the floodplain has decreased the risk of massive eutrophication events, improvedthe water levels in small oxbows and some semi-aquatic areas, and conserved theexisting species diversity in aquatic habitats (after e.g. Bondar-Kunze et al., 2009,Funk et al., 2009, Sommerwerk N. et al., 2010).‣ National Park Donau – Auen (Austria): side arm restoration and river bankrestorationProjetc’s summary:To enhance riverine — morphodynamics, several sidearms have beenreconnected since 1995 (Rkm 1905.0-1906.5; 1905.2-1902.0; 1910.1-1906.5) andsince 2005 river embankments and grayness have been removed from 2.85kilometres (Danube Rkm 1885.75-1882.9) and from 1.2 km (Danube Rkm 1883.1-1881.9). The long-term goal of the project is to come as close as possible to the preregulationstatus of this Danube section. Implementation is by the Austrian WaterwayAgency (via donau) and Danube Floodplain National Park subsidized by the EULIFE-Programme.66
