Project name:5. The LIFE Project „Wild river l<strong>and</strong>scape of the Tyrolean Lech” AustriaProject period: 2001 – 2006Beneficiary: Environmental Protection Authority of TyrolPartners: Federal Ministry of Agriculture, Forestry, Environment <strong>and</strong> WaterManagement, WWF AustriaBudget: 7,8 Mio EuroLife contribution: 50%Project summary:The Lech in northern Tyrol is characterised by huge gravel banks <strong>and</strong> broadareas of lowl<strong>and</strong> riparian forest. It is the last major river in the northern Alps that is ina semi-natural state. For over 60 km, the highly braided river occupies a gravel bedthat in parts is up to 100 m wide. The course of the river is constantly changing dueto erosion <strong>and</strong> deposition.Situation before restoration:In the past, however, flood disaster <strong>and</strong> increasing pressure from humanactivities have led to river regulation measures which in certain sections haveseverely narrowed the riverbed. The construction of debris dams across smalltributaries <strong>and</strong> growing exploitation of gravel from the river bed have also contributedto river bed deepening <strong>and</strong> the lowering of the groundwater tables. Particular thediminished river dynamics have caused a decline of endangered speciescharacteristic for gravel banks including the German tamarisk (Myricaria germanica),the pink-winged grasshopper (Bryodema tuberculata) <strong>and</strong> the little ringed plover(Charadrius dubius).Situation after restoration:The main objective of the LIFE project is to restore characteristic habitats ofthe Lech River by widening the riverbed of over 6 km of its length.
