old specimens sometimes 250 cm (in Belgium about 150 cm and 15 m high)

@Campoverde

I am talking about dendrology
not about forestry (only part of dendrology)
we mesure circumference (IDS!)surely and never diameter
that is not the same

Davidia involucrata: introduced 1897 at Des Barres and again in 1899 for Vilmorin by Wilson, so no real old trees here; do not know of reaching 100 years here (in Belgium up to +/- 12 meter and +/- 100 cm circ.), but possible: at least one is 80 years old at Edinburgh

the rest later this evening

Deutsch I can read, but not answer. I think you still would like to know how old these become average and here in Western Europe Gymnocladus dioica : the largest specimens in Belgium are maybe +/- 100(-150?) years old and 275 cm x 25m, not at Kew nor Edinburgh such old ones, sometimes very slow grow...

in the dendrology

we take measurements at 'breast height' here this is at 1,52 cm
that we measure the circumference of the trunk
(in England it is often at 1,30 I believe)

(of course it is important to take always the same height
and by preference the circumference, in order to compare easy)

also
Koelreuteria paniculata

these and two previous are really old, if reaching 100 years in Europe

For Aesculus flava, I think 100 is a good average for the oldest trees in Europe (one at Kew is about that age, older I can not track).
If there are older trees (I do not know, perhaps possible) there will be only a few (it is introduced in 1764)
