Perspective for mammoth tree in German front garden

Unfortunately, there are also forestry officers (with the emphasis on -officers) at the "zuständigen Landesbetrieben". Apart from books by Mr. Wohlleben, there are also dozens of podcasts that will give you a pretty good understanding of the subject of trees. And: yes, he has a forestry district to manage and can't sneak away to autograph sessions ;-)

King Wilhelm planted 5000 mammoth trees in southern Germany in 1850. Currently, about 200-300 of them still stand, approximately 40 in the [willhelma] in Stuttgart ;) Height about 30m.

Just as a reference for how they grow in Germany.

How about the house and tree?

The tree is gone. Regarding the house, the earthworks began on Tuesday.

Oh... was he no longer healthy?

But experts explained to me how strongly it will continue to spread, and that would have been incompatible with the construction project.
