LIFE + Traisen project: Goals - biodiversity in the wetlands

The goal is establishing and interlinking the new Traisen branch with surrounding bodies of water and the floodplain landscape. The ecological upgrade of the habitat will significantly improve the biodiversity in this part of the Tullnerfelder Wetlands Natura 2000 area.

The LIFE+ Traisen project is finished!

New Traisen river landscape

Goals in Detail

  • The greatest possible protection of the existing precious natural environment in the wetlands area
  • No detrimental changes to the floodwater situation for local residents
  • Establishment of a meandering river, which can further develop dynamically in future and provide new habitats in bodies of flowing water
  • Creation of manifold structures in the water-land transition section of the bank area of the new Traisen river
  • Establishment of new bodies of standing water, enriching the wetlands through a variety of water
  • Creation of a floodplain along the new course of the river with frequently flooded sites. Here, the site prerequisites are in existence for the development of the soft wetlands, especially those for the white willow wetlands.
  • Increasing the share of the typical wetlands and river habitats, which today amount to just 6% of the surface in the entire Natura 2000 area
  • Fish passable integration of the wetlands area and individual bodies of water in the wetlands with the new river Traisen, sustainably promoting the fish fauna of the Danube, the river Traisen and the bodies of water in the wetlands as a result. At least 30 species of fish will benefit from this. Among these are 15 Annex II species.

Ground Water and Flooding Conditions

The flooding situation for settlement areas remains unchanged by the project.

Ground water conditions are only changed to a minor degree in the area close to the river Traisen. Ground water utilisation, such as wells, for instance, will not be affected.
