Awesome! Did you check the link at the bottom for Scotland's top trees also? Any US cities or states do anything similar to this, separate from champion tree reg?
Hardly any old historic trees in the US to celebrate. We are edjerkated to fear decay, and mistaught that reduction cuts are not as good as removal cuts. Witness the Wye Oak--2 miles of cables, but no reduction cuts. Flop.
Sure would like to ungirdle that second one...cabling is not trusted in the UK (or Italy, etc.), so they butcher and use chastity belts instead.
Each society has myths and biases to overcome.
