General National Id Bulgaria_01 Site name Persina Nature Park, protected site "Kalimok-Brashlen" Summary The project was carried out in the period 2002 – 2008 by the Ministry of the Environment and Water in Bulgaria and the main donor was the Global Environment Facility (GEF). The performance was the restoration of two wetlands along Danube River by construction of engineering facilities, including sluices, channels, dykes to protect the adjacent land, as well as access roads. The project aimed to enable water flow into former wetlands, provide options for controlled flooding, optimized trapping of nutrient elements, and restoration of biodiversity and fish populations.

The technical design for Kalimok-Brushlen includes inflow and outlet facilities with the following dimensions: - Inflow sluice with dimensions 2x1.5/1.00 m and max. capacity 18.6 m3/s - Inflow sluice 2.0/1.5 m and capacity 20.5 m3/s. - Outlet 2 x2.0/1.5 m and capacity 37.3 m3/s. Constraints Possible appearance of disease because of mosquitoes Favourable preconditions Due to the hydrogeological conditions of the sites, parts of the wetlands continued to exist and have a high potential for restoration.

Key lessons When plenty of stakeholders are involved, it would be appropriate to provide longer groundwork. Participatory approaches to wetland restoration design were critical for Project success, which hinged on changing people's perceptions of wetlands, and gaining the full support for restoration among authorities and stakeholders. PA Local Consultative Councils and public awareness campaigns effectively supported stakeholder involvement. Controlled restoration is a step in the right direction and is allowing large- scale experimentation and studying of nutrient trapping processes. Solid knowledge on the baseline and the desired ecosystem status should be embedded early in project design phase.
