Establishment of demarcated areas
Article 5
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) a zone including the infested plants and all specified plants which are liable to become infested within a 100 m radius around infested plants (‘infested zone’); (b) a buffer zone with a width of at least 2 km beyond the boundary of the infested zone. 2. The delimitation of the demarcated area shall be based on the scientific principles, the biology of the specified pest, the level of infestation, the particular distribution of the host plants in the area concerned and the evidence on the establishment of the specified pest. 3. For the purposes of taking eradication measures referred to in Article 8 and where the competent authority concludes that eradication of the specified pest is possible, taking into account the circumstances of the outbreak, such as its size and location, the level of infestation or the number and distribution of host plants, the width of the buffer zone may be reduced to not less than 1 km. 4. For the purposes of taking containment measures referred to in Article 9, the buffer zone shall be of a width of at least 4 km. The width of the buffer zone may be reduced to not less than 2 km, taking into account the circumstances of the outbreak, such as its size and location, the level of infestation or the number and distribution of host plants. 5. Where the presence of the specified pest has been officially confirmed in the buffer zone of a demarcated area for containment, Articles 17 and 18 of Regulation (EU) 2016/2031 shall apply.
