Project summary

Edit project overview to modify the project summary.


Under the heading of "murerleben" already the second LIFE - project on the river Upper Mur runs in Austria. After completion of murerleben I, murerleben II started, considering the monitoring results and lessons learned:

• to enhance and support the previously implemented stepping stones focussing on their up- and downstream impacts.

• to create large connected and diversified habitats in the river and its alluvial forest areas

• to support the consolidation of the revitalized sections

• to enable those species which need various, local separate habitat structures, such as amphibians and kinds of fish to benefit from these contiguous habitat complexes (wintering, spawning, summer quarters)

The new LIFE+ areas were selected consciously in due consideration of previous projects in order to strengthen the already taken measures and to create a related restructuring stretch of river. The measures, but also the synergy effects of the measures, are scientifically examined in a monitoring programme aiming at documenting and maintaining the success of the projects. The programme is going to continue until 2015.

In the present second LIFE+ project from 2010 to 2015 investments of about EUR 2.8 Mio. are planned, 50% thereof is financed by the EU. 7 new measures are projected in connection with “murerleben I”

• Revitalisation or recreation of 7 distributaries and widenings

• Initiation of 17,7 ha new areas with alluvial forest

• Implementation of ponds serving as habitats for amphibians (13,000 m²)

• Reactivation of approximately 10 ha flooding area

In accordance with the objectives of the Natural Habitats Directive and the requirements of the EU Water Framework Directive in the two LIFE-Projects 16 water segments of the river Mur (a total length of 90 km) are planned. The implementation regards the preservation of the biodiversity, the dynamic river development as well as the improvement of the passive flood protection.
