Division II.2 Selection of sample trees

In principle all trees in the total plot shall be monitored. In the case that the plot has many trees (e.g. dense stands), a sub-plot may have been defined to be used for the tree assessment. In this case the trees in the sub-plot shall be monitored. The size of the sub-plot at the time of the inventory should be large enough to give reliable estimates for stand increment over the entire measurement period. The exact size of this sub-plot shall be determined and reported.

All trees with at least 5 cm diameter over bark shall be individually identifiable by numbering.
