Residents' perceptions are intangible ideas that may impact tangibly on coastal and dune management strategy and contribute truly for the sustainability of coast and dune restoration project. This study utilizes a qualitative approach to investigate residents' perceptions of the effectiveness of the measures implemented by Sefton Council to protect the Hightown dunes and coast from the risks of coastal erosion and flooding, and preserve local biodiversity. Findings revealed that residents regarded the measures as ineffective and considered the area safe so long as climatic conditions remained consistent. The study highlights the necessity of local community involvement in comprehensive coast and dune management plans to ensure project sustainability.
