Management of succession processes and improvement of the quality of the habitats and protected wetlands species in Srebarna Managed Reserve Wetland

The project implements activities provided in measures 22 and 109 of the National Prioritised Action Framework (PAF) for NATURA 2000. Realization of a western canal will create conditions for annual inflow of Danube River water into Srebarna Lake in quantities allowing for enhanced water circulation, mobilization and outflow of silt and accumulated detritus. That action has been motivated in the actualized Management Plan of Srebarna Managed Reserve approved by the Minister of Environment and Water. The canal is going to be soil built. Most of its construction is going to be achieved by deepening of the floor of the naturally existing channel and formation of the sides and banks. Construction concretes and mixes will only be utilized for building of an overflow and a precipitator. The canal is going to provide an increased flow of the water in the lake and natural outflow through the eastern canal of organic silt, mineral and organic substances dissolved and suspended in the water. Simultaneous functioning of western and eastern canals will lead to water exchange between the river and the lake and subsequent retardation of succession processes. The project includes excavation of silt and accumulated detritus and export of floating reed mats. This will additionally retard eutrophication and contribute to achieving and maintaining of favorable statuses of target natural habitats and populations of species of significant conservation value. Within the projects frame, reed harvesting will be carried out. A research of old pelican nesting places is going to be held in order to pinpoint best spots for construction of new pile platforms for nesting of Dalmatian pelicans. Feeding grounds for fish-eating birds will be improved by annual stocking up, carnivores’ access to nesting grounds is going to be limited and existing real-time monitoring system will be improved by installing new video surveillance cameras and photo traps in key areas for respective target species.
