Division III.3 Observation and recording

All species on the intensive monitoring plots are of interest; however priority should be given to the main tree species on the plot. Member States are free to include more species. In this case, however, each species should be recorded separately. Only events that have occurred and/or have changed their frequency/intensity since the last visit should be recorded. As the individual phases of phenological phenomena occur, assessments shall be repeated until the phase is completed.
