Mapping River Pollina

The Pollina River, a key example of a Mediterranean temporary river, stretches 34 km from its headwaters to the sea, covering high altitudes and significant natural areas, including parts of the Madonie Regional Park. The river basin includes various Nature 2000 sites and historically supports the European eel, a species now rarely found due to river fragmentation. Despite the river’s high overall environmental quality, barriers near the river’s mouth disrupt hydromorphological dynamics, affecting water permanence and habitat availability for the eel and other species.

The Pollina River faces challenges from existing barriers that hinder natural sediment flow and limit the accessibility of habitats crucial for species like the European eel. While the water quality is rated as ‘good,’ the ecological condition, especially concerning macrophytes, is ‘poor.’ Removing these barriers presents an opportunity to restore the river’s natural state, reconnecting habitats and supporting biodiversity. This project aims to address the lack of comprehensive barrier data and promote the benefits of barrier removal to decision-makers and the public, setting a precedent for future river restoration efforts in Sicily and beyond.

Study Track:

• Conducting preparatory desk research to review existing barrier and eel population data.
• Implementing participatory field visits to map barriers and assess habitat availability.
• Synthesizing data to produce a comprehensive study and prioritization of barriers for removal.

Advocacy Track:

• Engaging decision-makers and stakeholders through round tables, field visits, and public discussions.
• Promoting awareness of the ecological benefits of barrier removal through social media, a documentary, and an infographic.
• Building local capacity and public support for future barrier removal initiatives.
