Issue 6: Communication
• Expert-networks exist, eg. EUCC and European Dune Network but are NGO’s
• Need of an expert-network among government agencies ? • To enhance awareness and integrated approach: need of
expert-network not only among conservationists but also between conservationists and other social and economic sectors
