MonStur in the Danube Project

Sturgeons, the most endangered group of species worldwide, are facing a perilous situation in Europe. These migratory species, which once freely swam from the Black Sea up to Germany, now find their ecological corridors severed by multiple barriers. Human interventions - such as hydropower, sediment extraction, navigation, river channelisation, by-catch and illegal fishing - are exerting severe pressure on habitats and populations, calling for immediate, coordinated actions.
The EU Strategy for the Danube Region (EUSDR) recognizes migratory sturgeons in the DRB - the world’s most international river basin - as flagship species and key indicators of habitat connectivity and ecological corridors. Their protection is a prominently priority within the EUSDR.
In this context, the MonStur in the Danube project aims to establish a genuinely transnational and sustainable sturgeon monitoring system in the Danube River Basin. Its core ambition is to integrate existing information from past projects with newly generated data, creating a first-of-a-kind DRB-wide collection of population data. This effort will consolidate currently scattered datasets and offer the geographic range of sturgeon species .
In addition, MonStur will include a comprehensive habitat inventory. This will build upon and expand the dataset developed under the DTP MEASURES project, adding additional information (i.e. abiotic parameters), vital for the legitimate description and understanding of habitats.
Challenges
Key challenges of the ambition include:
- Combine all relevant knowledge on a macro-regional scale
- Engage actors in continuous cooperation and data sharing;
- Ensure long-term hosting and continuous updating of jonit databases;
- Stimulate extensive use of data for improved conservation measures and policies.

About the project
The project’s intervention logic effectively targets these challenges:
Key processes
- Set up a sturgeon monitoring system as a joint tool to be tested by partners;
- Enhance sustainability via cooperation and commitment of policymakers, expert institutions and other stakeholders;
- Close critical knowledge gaps, leading to new, effective policies.
New policies
- A sturgeon action plan will set out harmonised protection measures for habitats in a transboundary area;
- Joint recommendations for infrastructure planning will decrease the deteriorating effects of navigation and infrastructure interventions on sturgeons.
Conclusion & Results
- An analysis report will conclude learnings and recommendations, and provide inputs for the improved sturgeon chapter of Danube River Basin Management Plan’s (DRBMP) 2027 update.
- The joint sturgeon monitoring system would be integrated into ICPDRs Transnational Monitoring Network (subject to agreement and approval of the ICPDR). It will also stimulate the uptake in other sturgeon regions or expansion into the Black Sea region.

Partners
In order to help a sustainable DRB-wide solution, a broad and balanced partnership is created, covering 12 DRB countries and including: the ICPDR; ministries; sectoral agencies and authorities; higher education and research institutions; specialised NGOs. Partners are contributors to policy making with vast experience in river basins, ecological corridors, and protected species/habitats, embedded in relevant national and macro-regional networks, and who are represented in relevant ICPDR Expert and Task Groups and EUSDR PAs.
