|Conservation strategies for forest and wild river in Gesaeuse: the Johnsbach Beck restoration|
The natural habitats in and beside the River Enns as well as the Johnsbach brook improved significantly with the implementation of this LIFE+ funded project, delivered by the National Park in the River Enns and its surrounding ecosystems. Restoration actions took place in multiple sites to re-establish an ecologically functioning wetland along the water courses and tributaries, with focus in connectivity (transversal and longitudinal) and landscape diversity.
Works in the rivers Enns and Palten included the creation of a new estuary in their confluence. Bank reinforcement structures along 500 m of the River Enns were replaced by typical riverine structures (i.e. gravel banks, bank erosion areas, piles of deadwood) which are developing. A new large pond for amphibians was completely cut-off from both rivers to prevent the immigration of fishes. Common frogs (“Rana temporaria”) and European toads (“Bufo bufo”) breed here.
Another target was the re-naturalisation of the floodplain forest for enhancing longitudinal connectivity of the river Enns. 306 ha of spruce dominated forests are now a natural mixed forest. Restoration of the River Enns and its surrounding ecosystems are also in line with a long-term strategy to protect special habitats and endangered species (i.e. Black woodpecker (“Dryocopus martius”), Eurasian pygmy owl (“Glaucidium passerinum) and the Rosalia longicorn (Rosalia alpina).
With focus on mountain pastures and species (i.e. black grouse (Tetrao tetrix), yellow bellied toad (“Bombina variegate”), etc.), the regulation of grazing intensity and access to drinking water in within the project area were also a priority.
A monitoring programme was established for the assessment of restoration outcomes. Increasing public awareness and dissemination of results are supported by public activities. For instance, specially trained wardens are to guide visitors and provide information on restoration outcomes in terms of habitats and landscape diversity and services. In addition, a thematic trail with interactive information facilities is in place.
The River Restoration Centre would like to thank Daniel Kreiner from the Gesäuse National Park for providing the information and photographs for this case study.
Work included educating the community on environmental protection and promoting environmentally-friendly behaviour.
