"Age" in these first two types will invariably be a minimum age rather than true chronological age owing to the difficulty of sampling a tree exactly at the point of germination.
Extrapolations are ages derived by regression from age/size relationships (e.g.
Ranges of ages derived by extrapolations are welcome and can be accommodated in the database.
