Which fast-growing tree species in a garden to have the equivalent of 0.5 to 1 stere of wood per year?

The black locust is classified as an invasive species in Belgium: https://www.provincedeliege.be/sites/de ... cia%29.pdf

(a lot of other interesting info)

The black locust is classified as an invasive species in Belgium

Not only is its wood very dense and therefore burns much slower than other species, but it is also perfect for making rot-proof stakes.

Yes I will have to find locust!

Here are the pictures...

Cut the 2 firs (about 7-8 m) which have released old willows and obviously a birch too? They logically grew like a "cauliflower" under the tree ...

I have already topped the willows, for the birch I am awaiting your advice ...

Here are the other locations on the ground where I could plant stuff:

And you have not yet made a paddle wheel (Or something else) to make electricity with this wonderful little stream?

Whatever the tree, if you want interesting sections, you have to prune it every 3 years, no more.
If we want to harvest every year, that means having three times the area and rolling.
Pruning every year hurts the trees.

Willows or poplars are full of water and therefore full of air when dry.
The black locust, I did not know that it grew quickly, that's why I proposed the ash supporting the size well in tadpole (unfortunately prone to diseases in some regions)

Pruning every year hurts the trees.

Insofar as (if I understood correctly) it is a question of planting to obtain firewood, it is not really important and young the locust tree produces a very straight trunk (hence its use for stakes) which then swarms.

If in 2009 but the project screwed up (do a search you will find) and there the stream is very high compared to normal ...

In 2019 I had developed another project: a foil generator I would tell you about it soon ... it was one of my resolutions

If I want to redo a paddle wheel, now that I know how to weld better, I could recycle the vertical structure from the other photo!

Swarm? No, it sucks readily, especially if it is cépé * ... But a tadpole treatment is likely to be very problematic with black locust because of its XXL spines in the juvenile state.

* Coppicing is what biomass farmers do for caloric purposes: they plant and 2 years later, when the subjects have a well-developed root system, they pass the rows to the mulcher, which causes bushy regrowth in clusters ( suckering works more on adult subjects), which then increases the mass to be harvested.

Christophe, you say:

Wasn't it a watchtower?

The subjects in the photo are in my opinion several years old. If you take it all in, you will have to wait a few years before you can harvest.
Tadpole pruning allows regular harvesting without destroying the tree
But to prune every year, we have bundles
Finally, the locust, I have no experience so I leave the specialists.

This subject interests me greatly for the same reasons as Christophe.
there is the willow in short rotation to make platelets (must be crushed in addition to cutting). it must then be able to work with a pellet stove?

[Christophe]

If it were a dwarf watchtower! But am too big now!

suckering and layering what's the difference?

To come back to my specifications: it would be good to have 50mm branches for each harvest. As I have several possible locations, no worries about making rotations ... over 3 years?

ps: what are the red shrubs behind the tree that I fell? It looks like a species of willow too ...
