Assessing naturalness of coastal dune ecosystems through community (citizen) science: A protocol for Mediterranean beaches

open access: yesEcological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
A standardized citizen science protocol enabled trained secondary school students to collect reliable data on beach and coastal dune naturalness across Italy. The method provides a scalable and cost‐effective tool to support ecological assessment, identify vulnerable sites and inform coastal conservation and management.
