The UK government recognises that current land and conservation management practices may have to change so that the stricter protection envisaged for Natura 2000 can be provided. For example, if a land owner objects to an existing SSSI being made a Natura 2000 area then the Secretary of State can declare a Special Nature Conservation Order on the site which effectively annexes the site from its legal owner. This is, in effect, a right of compulsory purchase which has been available for existing SSSIs but which has been exercised only once since 1949. The Government expect the Natura 2000 initiative to be taken forward by means of positive partnerships between landowners on the conservation agencies. Natura 2000 sites apply both to land and water areas.
Special problems exist with the accurate designation of marine conservation areas.
Where-ever possible, the boundaries will be straight lines and fixed with reference to prominent features such as permanent buoys, rock or coastal features. The regulations that apply to marine Natura 2000 areas contain innovative measures to safeguard the marine environment. This is likely to require sustainable fishing measures. Sustainable recreation activities in marine Natura 2000 areas will be encouraged. The marine environment around the UK coast is still relatively unexplored.
