Natura 2000 is protected European nature, following the European Birds (1979) and Habitat Directive (1992). These directives aim to protect and restore natural habitats and wild flora and fauna, with the emphasis on habitats and species threatened at a European level. They are listed in the annexes of the directives. European legislation has been converted into Flemish legislation. An essential part is the realization of a European ecological network of protected areas, the Natura 2000 network. In those areas, "special protection" or "bird and habitat directive areas', measures must be taken and conditions created in order to maintain or improve the present state of species and habitat types.
