An ancient technique that fell out of favour in the past 400 years. If you really get into the historical side of it, there are archaeological records of coppice timber being used thousands of years ago. It’s very solarpunk.

As for videos, I have no idea. I’m a qualified arborist so my knowledge of them started by figuring out tree physiological response to pruning and then working out the techniques from there. In the past few years there has been a significant resurgence in information and if you lived in Europe, you would have been exposed to it more than any other continent for years prior. I’d bet there are videos, technically I should be one of the people making them.

There was a book on the history released recently: https://www.williambryantlogan.com/ - called Sprout Lands. It’s not a technical manual, more of a flowery piece dedicated to the discovery of the cultures that performed it and why it worked from a functional sense. Worth reading.

And, unless it’s on FB, the only place I know of discussion for it is https://www.teddit.net/r/coppicing - maybe if Lemmy picks up and a “tree” community (not cannabis) gets going. There are probably some arboricultural forums still plodding along but we all know how centralisation went for them. Composting isn’t the right niche for it, farming, while associated, isn’t either.

Worm composting is my traditional composting method. The other method would be chop-and-drop composting but accelerated through the use of coppice and pollard cutting techniques by planting trees/shrubs densely and intended for that very purpose (but mainly pollard due to herbivore pressures).
