Establishment of demarcated areas
Article 4
1. Where the presence of the specified pest is officially confirmed, the Member State concerned shall, without delay, establish a demarcated area consisting of: (a) an infested zone, including at least the area within a radius of 10 m around the location where the specified pest has been found to be present or in the case where the specified pest is found in a cultivated field, the entire field and (b) a buffer zone of a width of at least 500 m surrounding the infested zone. 2. The buffer zone shall only include water courses and areas that are saturated with fresh water. Where the infested zone includes a part of a water course, the buffer zone shall include that water course for a length of at least 1 000 m downstream and 500 m upstream from the location where the specified pest has been found to be present. 3. In cases where buffer zones of different demarcated areas overlap, a new demarcated area shall be established including the area covered by the relevant infested zones and buffer zones, to ensure a clear delimitation of the demarcated area. 4. If the specified pest is found to be present in the buffer zone, the delimitation of the infested zone and buffer zone shall be amended accordingly. 5. Within the demarcated areas, the competent authorities shall raise public awareness concerning the threat of the specified pest and the measures adopted to prevent its further spread outside of those areas. They shall ensure that the general public and professional operators are aware of the delimitation of the demarcated areas.
