Project summary

Edit project overview to modify the project summary.


In accordance with the division designated for the INTERREG IIIA Project, the Lower Mur Valley habitat encompasses the Austrian border segment of the Mur River between Spielfeld and Sicheldorf (the “Grenzmur”), which forms the border to Slovenia, as well as the alluvial and cultural landscape bordering it to the north, with a total area of approx. 137 km². In western and eastern direction the area extends from Spielfeld all the way to the Austrian-Slovenian state border near Bad Radkersburg. This region encompasses the “Styrian Grenzmur with the Gamlitzbach and Gnasbach streams” European nature reserve, as well as, in part, the “Parts of the South-East Styrian hill country, including Höll and Grabenland streams” European nature reserve.

During the 5-year project (2003-2008), 220,000 m³ of bed load were added along a total stretch of 1,800 m in order to prevent any further depth erosion of the riverbed of the Mur. Furthermore 32 ha of dynamic Mur and alluvial habitat were created as well as a total of 45,000 m tributary streams were reactivated and/or extended. The total value of this four year project was 3.8 million €. 50% of the project was financed by the European Union (Interreg IIIa), whereas national contributions are distributed variably between project applicant and co-financers.
