LIFE+ Traisen: Success of the project
The new Traisen river is now also the connection to the Danube through which fish can pass unhindered. It is free from obstacles and has a natural design. The main objective of the project was to improve the habitat situation in this part of the European conservation area “Tullnerfelder Au”.
Traisen project area
New flowing waterbody
Flood zones covering an area of 60 ha were actively created on the new river. They are the location of the priority habitat for the silver willow wetland, which is part of FFH type 91E0*. These riparian forests are typical of the area. According to the experts, the young riparian forests are developing very well and will eventually achieve their typical form. Willows and poplars established themselves independently on the new bank zones and enrich these typical river habitats in the Natura 2000 area by around 5%

Meadows and dry areas
The project battled unwanted plants, so-called neophytes, on an area of 25 hectares in the new section of river and on the meadows with lasting success. Naturally, only mechanical methods were used. This way, the goldenrod could be almost entirely removed from the meadows.
Maintenance and upkeep
As all ecological effects and the natural dynamics also had to be ensured on a permanent basis, agreements were concluded on tolerance and on permanent maintenance measures. Most measures took place on third-party land, so the land owners were compensated for various pecuniary disadvantages. That was the basis for implementing the project. This financing was processed without the utilisation of LIFE monies.
The river landscape will now continue to develop naturally and undisturbed. Nature itself can create new habitats and change old ones. The positive ecological consequences of the new Traisen can be felt far beyond the project’s limits and are sustainably effective.
