Article 2
1. The systematic network of observation points, hereinafter ‘Level I points’, corresponding to a grid composed of units measuring 16 × 16 km, covering the entire territory of each Member State, hereinafter referred to as ‘the grid’, shall be utilised to carry out annual crown conditions surveys. Those surveys shall be carried out using the methods set out in Chapter 2 of Annex I. 2. Observations shall be made at each intersection point falling on forested land. 3. Member States may use denser networks than the Level I points where it is necessary for the preparation of their annual reports in accordance with Article 15(1) of Regulation (EC) No 2152/2003, and in order to obtain representative data at a national or regional level.
