Project name:4. The LIFE Project “Upper Drava-river valley” AustriaProject period: 1999 – 2003Beneficiary: Water Management Authority of CarinthiaPartners: Federal Ministry of Agriculture, Forestry, Environment and WaterManagement, Nature Conservation Authority of Carinthia, WWF AustriaBudget: 6,3 Mio EuroLife contribution: 26%Project summary:The upper Drava in Carinthia in Austria is a typical Alpine river which hosts thelast remnants of inner alpine floodplain forest associations and endangered speciespopulations such as the Danube Salmon (Hucho hucho). The alder-ash floodplainforests are the best preserved and largest ones in the entire Alps. It is one ofAustria’s largest rivers which have being preserved as a free-flowing river on over 60km without any dams.Situation before restoration:The upper Drava in Carinthia, once a highly braided river with many side armsand gravel banks, has met the same fate as so many other Alpine rivers in the 20thcentury: the river bed was canalized, bends were straightened out and branches cutoff from the main stream, dams built and farming in the floodplain area intensified.This has brought an enormous loss and degradation of the natural freshwaterhabitats including alluvial forests and a decline of species populations including theDanube salmon (Hucho hucho) and the crayfish (Austropotamobius pallipes). Majorproblems, including the deterioration of natural flood retention capacity leading togreat risk of flooding for the whole area as well as deepening of the river bed (e.g.deepening of 2 cm per year) which caused a fall in groundwater tables, have forced afundamental reassessment of Carinthia´s approach to river management. Starting inthe early 1990s, the Water Management Authority of Carinthia has started restoringthe river to a semi-natural state again. New efforts were made to preserve and44
improve what was left of the rich natural environment and have to date culminated inone of the largest river restoration projects in Europe.Situation after restoration:The main objective of the LIFE project was to maintain and improve naturalflood protection and the river dynamic processes and therefore to improve naturalhabitats and typical species populations. This was achieved through restoring threeecological “core zones” by river bed widening and reconnection of the former sidearmsystem with the main river of over 7 km of its length. An additional focus lay inthe restoration of the natural floodplain forests, the protection of endangered speciesand the creation of a combined biotope system along the whole river valley.Project results:• Better flood prevention: On 200 hectares natural flood retention capacityimproved by 10 million cubic meters.• Reduced flow velocity: The speed of the flood wave slowed down by morethan one hour.• River bed deepening stopped or even rose.• More space: 50-70 ha more natural river habitats as river islands, gravelbanks, steep banks for engendered species such as Danube Salmon, CommonSandpiper and Kingfisher created.• Fish population doubled such as the grayling.45
