1. XX1997.PLV: Contents of reduced plot file to be used in combination with the survey of ground vegetation
2. Preference should be given to trees that are clearly visible when standing outside the plot, because the high frequency of the observation may affect the condition of the ground vegetation on the plot.
3. Each time (day), or situation (inside outside fence), that an assessment of the ground vegetation is made on a given plot, a survey number is given.
4. Identification of visible ozone on (small) tree, shrub, and perennial species within the LESS and (optional) the ground vegetation within the Level II plot
5. In order to achieve comparability of results between countries, a common sampling area (CSA) of 400 m2, representative for the ground vegetation of the Level II plot, is mandatory.
6. In order to achieve comparability of results between countries, a common sampling area (CSA) of 400 m2, representative for the ground vegetation of the Level II plot, is mandatory. This area can be reached as the sum of smaller sub-plots within the Level II plot area.
7. For the symptom assessment of small tree, shrub, and herbs species within the LESS and the ground vegetation (optional) within the Level II plot the following information is required for each of the randomly selected sampling spatial unit:
8. Trees should be selected from those on which crown condition assessments are carried out. Preference should be given to trees that are clearly visible when standing outside the plot, because the high frequency of the observation may affect the condition of the ground vegetation on the plot.
