It never was a question about the strength of the trees. It has always
been about the cables and the load.

I would tend to agree, as the big redwood is massive (30 feet in
circumference).

For scale, there's actually a person, wearing blue, in the cargo net
right next to the tree, fixing the blocks for the cable that we later
wrapped around that tree.

BTW, even the little redwoods are not all that little:
