Protect the inheritance
Implementing regulations with a view to protecting out natural heritage is a new phenomenon. Action plans, treaties, agreements or directives have been submitted at the international, national and regional levels. Among these regulations, three of them concern large coastal zones and require extensive knowledge as regards benthic species and long-term monitoring :

The common denominators of these regulations are as follows :
