That is not true. Annuals have to rebuild the entirety of their biomass
every year, and woody plants don't. The biomass of the wood can be
mortgaged over centuries, and has a certain value in itself.

The majority of the uplands of the UK will not support the high-margin
crops, so you earn NO money by growing them there. And the cost is not
necessarily high.

You can grow fungi on it and eat them.

The thing that struck me (knowing nothing about Alder seeds and their
edibility) was what rotten fire wood Alder makes!
