Project summary
Biomura LIFE06NAT/SI/000066
The BIOMURA project funded by the EU LIFE NATURA 2006 is among the first projects aiming at restoration of the degraded river morphology in Slovenia. Project goals was improvement of riparian and adjacent riverine habitats, protection of targeted endangered species and indirect implications for preservation of other animal and plant species and their habitats, increase of biodiversity and reservation of the natural landscape.
The area covered by the project has a surface of 1520 ha and is part of the Natura 2000 (SPA: SI5000010, pSCI: SI3000215). The area lies within high water protection embankments of the Mura River, between the villages of Bakovci, Dokležovje, Ižakovci, Melinci, Bunčani, Veržej, Krapje and Mota.
Intensive water use, activities in the river and riverside space and the change of land use in the Mura River catchment (chain of hydropower plants on the Mura in Austria, flood protection structures and facilities, water supply, management of agricultural land, urban development) have considerably altered the river space. At the border between Slovenia and Austria, the river bed of the Mura River has deepened in the last decades (by as much as 1.5 m; by 33 cm on average). This has changed the hydrological features of the Mura wetlands.
Although the Mura River has been straightened and the meanders cut-across, leaving behind oxbows, parts of the old channel are still recharged by the river, precipitation and groundwater. The processes of more relaxed, less controlled dynamics of the water flow, with a more frequent and easily spotted bank erosion, natural sediment transport and deposition, frequent flooding, river branches and oxbows, are especially present downstream of Veržej. The Mura river space in Slovenia, and at the reach bordering Croatia, is therefore among the richest ecosystems in Slovenia.
Proposed measures and actions: (C1) connecting the main river channel with the side branches; (C2) establishing conditions for appropriate water level at the site of the water inflow into side branches (more frequent and higher water level in the main channel, which enables the inflow of water into side branches at average and lower discharges); (C3) widening of the main channel where erosion channel banks and gravel bars will be formed; (C4) presentation of sustainable alluvial forest maintenance; (D1) sustainable maintenance (restoration) of side branches; (D2) establishing a system of smaller inflow/ outflow structures and mechanisms (wooden lock lifters, openings) in the chosen sites in the area of oxbow lakes and branches; (E7) local information centre Mota; (E8) regional promotional centre in Murska Sobota; (E9) information trail Veržej – Ižakovci (E1-E6, E10-E12), workshops, promotional and informational actions and sources: webpage, information bulletins, brochure, film.
The activities of the BIOMURA project aimed at improvement of growing conditions for 4 habitats from the Habitats Directive: Alnus glutinosa in Fraxinus excelsior, (Alno-Padion, Alnion incanae, Salicion albae); Quercus robur, Ulmus laevis in Ulmus minor, Fraxinus excelsior ali Fraxinus angustifolia; Rununculion fluitantis in Callitricho-Batrachion; Hydrophilous tall herb fringe communities of plains and of the montane to alpine levels. The conservation of targeted species for more than a third of the Natura 2000 qualification species on the Mura river should be ensured. Targeted species from that Annex II to the Habitats Directive include: 1 butterfly species (Callimorpha quadripunctaria), 1 amphibian species (Bombina bombina), 1 dragonfly species (Ophiogomphus cecilia) and 5 fish species (Misgurnus fossilis, Rhodeus sericeus amarus, Gymnocephalus schraetzer, Umbra krameri, Aspius aspius). Also, it is assumed that the living conditions of 29 other species of birds, butterflies, dragonflies, amphibians, reptiles and mammals improved.
