DANUBE4all: ecological groyne optimization in Duna-Ipoly Nature Park

On 10th July 2023, the DANUBEPARKS and WILDisland teams visited the Middle Danube demonstration site as part of the ongoing DANUBE4all project.

Located in Sződliget, approximately 30 km north of Budapest within the beautiful surroundings of Duna-Ipoly National Park, this project site showcases a remarkable opportunity for river re-dynamization and ecological restoration. The field visit was led by a representative of the Duna-Ipoly Nature Park, Hungary, and allowed us to discuss the provided actions, potential synergies, and follow-up projects and plan the future steps in detail.

Ecological groyne optimization

The highlight of this site visit was discussing the optimization of two river groynes, aimed at revitalizing this section of the river. By removing the roots of two groynes and adapting the area between them, DANUBEPARKS and its partners seek to enhance the natural flow dynamics of the river, benefiting various aquatic species, particularly juvenile fish. Moreover, the proposed measures aim to reduce wave stress and foster the creation of a small river island between the two groynes, which is expected to positively impact the overall biodiversity in this area. 

Monitoring of the site's biotic and abiotic parameters will take place before, during, and after the restoration process. This scientific survey will provide essential data to evaluate the effectiveness of the measures and guide future conservation efforts along the Danube River.

Stakeholder involvement

One of the key aspects of the DANUBE4all project is the close collaboration with local stakeholders. By actively involving them in the decision-making process and incorporating their valuable insights, the final design and implementation of the project will be optimized to meet the specific needs and aspirations of the region. This participatory approach ensures a sense of ownership and long-term sustainability, fostering a deep connection between the project and the local community.

It is worth noting that the initial plan for the groyne adaptation at the Middle Danube demonstration site was prepared and developed during the Interreg DTP DANUBEparksCONNECTED project, as the first of these kinds of measures in Hungary, with the strong support of the local stakeholders. Now it will be realized as one of the key DANUBE4all actions together with the restoration of the Upper Danube demonstration site - "Paradeis Insel" in Donau Auen National Park.
