Yea, I was going to mention age, but as a side-effect: pollarding
certain species also results in a trunk that is suitable for high-
quality, straight-grained wood in a species that would otherwise
produce spindly, thin trunks.
Certain desirable hardwoods (laurel comes to mind) don't build much of
a trunk unless they are aggressively pruned.
But I'm more into coppicing. Just mow 'em down, and your kids will
have firewood.
