Summary
Gerai (Balta Geraiului), a Danube floodplain between Gârcov and Islaz, was restored under the LIFE+ “Green Borders” project. Works completed in 2011 reinstated the hydrological regime on about 1,000 ha to secure breeding water levels and open-water patches for Ferruginous Duck (Aythya nyroca) and Pygmy Cormorant (Microcarbo pygmaeus). Since then, the area has gained stronger protection and outreach: on 13 June 2012 it was designated as part of the Olt–Danube Confluence Ramsar Site (46,623 ha), and in June 2013 WWF, APM Olt and local communities opened a visitor observation point at Gerai. Governance has also been updated: in May 2023 Romania approved the official management plan for the Natura 2000 sites ROSPA0024 “Olt–Danube Confluence” and ROSCI0044 “Corabia–Turnu Măgurele”, which cover the Gerai area. Recent pressures include recurring reed/grass fires; in August 2022, over 600 ha around Islaz in the “Teleorman Delta”, including Balta Geraiului, burned. Overall, the project’s hydrological reconnection and bird-habitat aims remain relevant, now framed by Ramsar and Natura 2000 planning, while fire management is an ongoing challenge.

Location of the project
Danube floodplain between the villages of Gârcov (west) and Islaz (east), at the Olt–Danube confluence. The site lies near national road DN54 (Turnu Măgurele–Islaz–Corabia) that connects the two villages.
NUTS Code
RO31 - Sud - Muntenia
Project's objectives
Restore hydrology at Gerai to facilitate water circulation and maintain water levels required by aquatic birds during the breeding/rearing season; improve hydrological conditions on ~900 ha of the floodplain.
Ensure favourable living conditions for Ferruginous Duck (Aythya nyroca) and Pygmy Cormorant (Microcarbo pygmaeus) by reconstructing nesting/feeding areas, applying best practices in fisheries/reed/forest management, reducing accidental/deliberate killing, informing local communities, and mobilising funding.
Implement a hydrological reconnection able to store up to ~4.2 million m³ during floods on a site of ~950 ha, via three control structures on drainage canals and a ~900 m feeder canal.

Monitoring is required/ongoing to track the status of target bird species and habitat condition, carried out by WWF and partners during LIFE+ and framed since 2023 by the approved Natura 2000 management plan.
Avian responses (including Ferruginous Duck and Pygmy Cormorant) and vegetation recovery, insects.
Maintenance
Maintenance consists of applying conservation management of reedbeds/fisheries/forests and keeping the site under a managed regime.

Key lessons
A focused, low-cost hydrological reconnection can deliver quick biodiversity gains. At Gerai, three control dams and a ~900 m feeder canal re-established water exchange on ~950–1,000 ha; within two years Ferruginous Duck breeding pairs rose from ~20 to ~60, demonstrating rapid avian response at site scale.
Locking restoration into formal protection and planning sustains outcomes. After works finished (2011), the area was included in the Olt–Danube Confluence Ramsar Site (2012), and an official Natura 2000 management plan for ROSPA0024/ROSCI0044 was approved in May 2023—providing a framework for ongoing management and monitoring.
Transparent local engagement helps when land is fragmented. The case documents consultations with village stakeholders/landowners from Islaz and Gârcov at project start, which supported access and acceptance for interventions on the floodplain.
Plan for maintenance and monitoring from day one. WWF lists “Monitoring” and “Maintenance” as explicit phases at Gerai, and reported that post-works monitoring showed the wetland “coming back to life,” with returning bird and plant communities—useful, concrete indicators for tracking success.
External pressures can erode ecological gains if unmanaged. Recurrent late-summer fires culminated in ~700 ha burned around Islaz in 2022 (including Balta Geraiului), underscoring the need to integrate fire-risk reduction and enforcement into wetland management.
Investing in low-impact visitor infrastructure aligns conservation and local benefits. The 2013 bird-watching observation point formalized access, supporting education and ecotourism while channeling visitors to reduce disturbance.

Transferability
Highly transferable to disconnected floodplain ponds where modest hydraulic works restore water exchange. At Gerai, three control dams and a ~900 m feeder canal reinstated flows on ~950–1,000 ha with quick bird recovery. Key cautions: secure legal protection/management plan, engage many small private owners, fund maintenance/monitoring, manage reed–grass fire risk, and calibrate water levels to breeding needs.
