Persina Nature Park – Belene Islands
Implementation of Priority Measures in the Ramsar Site "Belene Islands Complex", Persina Nature Park, Bulgaria
General Description
This project targeted the Persin Island wetlands in Persina Nature Park, Bulgaria – part of the transboundary Ramsar site "Belene Islands Complex" shared with Romania. It achieved three specific objectives:
- Enhancing management and control of incoming waters by modernizing and automating sluice operation on Persin Island.
- Improving the conservation status of the "Kaykousha" marsh through reed mowing and supporting open water area formation.
- Improving the conservation status of habitat 2340 (Pannonian inland dunes*) by limiting the spread of invasive false indigo bush (Amorpha fruticosa).
Innovative Aspects
The project features innovative smart modernization of wetland sluices with:
- Autonomous power supply (solar/off-grid)
- Mechanized gate operation
- Remote control capabilities
- Real-time monitoring system for wetland water parameters
This technology enables management that closely replicates natural water regime dynamics, even from remote locations, addressing a longstanding challenge in riparian wetland management.
Environmental / Social / Economic Aspects
Environmental: The solutions model a water regime closely resembling the natural one, restoring the typical riverine ecosystem of the Lower Danube and supporting transboundary biodiversity (fish and birds).
Social: Restored fish populations of wetland-reproducing species have a direct socio-economic impact on fishing – a traditional livelihood in the region.
Economic: Additional economic effects on tourism, hunting, forestry, and livestock farming in and around the Ramsar site. Climate resilience aspects are still being assessed.
Link to Spatial Policy
The project is closely connected to spatial policies on land use, wetland restoration, and water management in river basins. It supports the implementation of the Ramsar Convention, EU Habitats Directive (Natura 2000), and the Water Framework Directive at local and transboundary levels.
Challenges & Solutions Applied
Restoring lateral connectivity between the Danube and riparian wetlands (Persin Island) faces significant challenges due to protective dikes and infrastructure. Key challenges include:
- Presence of protective dikes limiting potential solutions
- Manually operated sluices in hard-to-access locations
- Lack of operational data on wetland water levels
- Ongoing deterioration of hydromorphological conditions in the Danube due to the Iron Gate dams
- Climate change effects on water availability
The smart sluice modernization directly addresses all these access and management challenges.
Key Takeaways for Replication
- The smart sluice modernization solution is successful and innovative for the Lower Danube region.
- Strong replication potential in other riparian wetlands: Kalimok, Srebarna, and others along the Lower Danube.
- Requires additional promotion to realize its full replication impact – stakeholder engagement was limited to the local level.
