This table explains the mapping between the former (until 2017) reporting rules for plant phases and the current one (phase_id).

During the COST725 project, and also in the early days of PEP725, only the well-defined BBCH plant stages were allowed in this database.
Since not all phases observed in phenology are defined within the BBCH scale, additional phases have been added over time. The new definition table now clearly differentiates between actual BBCH phases and new introduced ones - below the necessary translation table
