It is generally accepted that in order to survive, a species needs a minimum number of individuals. This means that several populations of the species need to be maintained at a minimum number and that exchange between these populations is needed. Core areas are ecosystems, habitats, and landscapes of European importance. They will in many cases also include important semi-natural systems, which are dependent on human activity, such as extensively used agricultural landscapes. Corridors and stepping stones , will improve the coherence of natural systems, facilitating dispersal and migration of species between the core areas.
Corridors are continuous structures like canals and wooded banks.
In restoration areas , damaged elements will be repaired or completely restored. Buffer zones support and protect the network from adverse external influences. In many cases the function of corridors and stepping stones will be compatible with appropriate forms of economic activity. EUCC works on European Ecological Network Because of her specific coastal expertise, the EUCC is actively involved in the elaboration of the Pan-European Biological and Landscape Strategy. Both projects are being supported by the Dutch Government, the Council of Europe and others.
