120509 Iasi, restoration in Bulgaria - Mr Vasil Uzunov

  1. 1. Protection and restoration of water ecosystems in Bulgaria
  2. 2. 1. Water management in Bulgaria – national and river basin level2. Four river basin districts/directorates3. 4 River basin management plans (RBMP) 2010-2015 2
  3. 3. Protected areas according the WFD Natura 2000 – more than 30% of the territory of Bulgaria 3
  4. 4. Measures in the RBMP concerning protected areas Administrative measures:• Bans and restrictions on construction of hydro-power stations at rivers in the protected areas• Bans on sand and gravel abstraction from river beds and bans on distraction of natural reparian tree vegetation. (This measure aims protection of reparian habitats and improving hydromorphological status )• Bans on discharge of waste water in the protected areas Investment measures(restoration )• Restoration of wetlands, natural conditions and river bed• Afforestation of river banks with free species• Remeandring• Constraction of fish passes• Biological strength of the banks, etc. 4
  5. 5. Example 1 - Restoration of Veselina Rivermeander near the Mindya Village, BulgariaWWF together with local people from Mindya village in the region of VelikoTurnovo, restored the connection of Veselina River, a tributary of Yantra, with itsformer meander near the village. When the river meander was cut off back in time,the river dug nearly 150 cm deeper into its bed, so now a threshold had to be builtto raise its level enough for enabling it run back to its old bed. 5

  7. 7. Example 1 - Restoration of Veselina River meander near the Mindya Village, BulgariaThe project objective is by conducting a number of technical, environmental and forest management activities to achieve ecosystem restoration of the river Vesselina in particular: • Conservation and restoration of biodiversity in isolated old bed of the river and correction of Vesselina river near by Mindya village; • Create favorable conditions for development of recreation and tourism in the region • Reduce the level of flood risk • Optimization of groundwater level and reduce the impact of drought and floods on agricultural land in river terrace; • Reduction of erosion; • Increased self-purification capacity of water flow in the region of isolated old bed of the river; 7
  8. 8. Example 2 - Restoration of the Russenski Lom River near Ivanovo Rock Monasteries •In the mid 20th century most of the lower flow of Russenski Lom floodplain River was fully diverted. •High water floods the road, dyke •When water overflows the dike it openings in the dyke can no longer go back into the river. •The flood in 2006 washed away the bridge and the alcoves on the island once again. •In this case, the water itself suggested the solution to the problem. •It is the first example in Bulgaria for application of the principle “more space for the river – more safety for people”, proven yet in mid 20th century.The project was implemented in 2009 by theRussenski Lom Nature Park Directorate,Club „Friends of Russenski Lom” and WWF withthe support of the Ministry of Culture and 8 was funded by WWF and the German Federal Ecological Foundation DBU

  12. 12. Example 3 - Restoration of the link between the Danube River and the wetlands of Persin IslandIn 2007 the wetlands of the Persin Islandwere re-linked to the Danube River underthe Project for Wetlands Restoration andPollution Reduction as part of the initiative“Lower Danube Green Corridor”. Theproject was carried out by the Ministry ofthe Environment and Water in Bulgaria andthe main donor was the GlobalEnvironment Facility (GEF).- The restored wetland is a man controlledfloodplain of about 2200 ha. The depth offlooding varies up to 2.5 m. At this waterlevel, four relatively large marshes shapeup in the eastern part of the island –Murtvo Blato, Peschina, Staroto Blato andDyulova Bara, as well as several smallerones. 12
