Yes we have redwood?s, but only in parks of castles, not in a forest.
I only know 3 redwood?s in our landscape with this diameter ( about 2 or 3 meter). They are about 130 years old.
archaic, now I understand it, we say archaisch or altmodisch.
We like to work with the dynamic systems, but youu can?t use them for every problem in trees. If the tree has a split, it?s mostly better to take static systems.
I hope I phrased it correct.
