The world tree Yggdrasil. At the foot of the tree is a well, which is presumably Urðarbrunnr. No caption or title provided in the work, but the illustration appears in a section of Grímnismál labeled "Om Yggdrasil" (Danish: "about (or "around", depending on context) Yggdrasil").

Which are your favourite?

Are you aware of any papers relating to productivity of theses species? I mean, tons of wood, per species, per planting scheme, per climatic area. I would like to add this information as well.

Hey Pablo, interesting topic. Would you add a column for "coppicig possible" or something?
Productivity in weight per area per year would indeed be super interesting.
Also another column for "other uses" for stacking functions

Yes, they have been coppicing for firewood in places for over a thousand years, so finding good locally adapted plants for that approach makes a huge amount of sense. ( Coppice Agroforestry by Mark Krawczyk : review here https://permies.com/wiki/203188/Coppice-Agroforestry-Tending-Trees-Product )

I'll also suggest that people know the ecosystem requirements of trees - some will hog water to get that excellent growth, which then denies water to native, locally adapted trees.

And please don't plant monocultures - most coppiced areas use more than one species, and only chop relatively small areas on any one year, and have been shown to improve diversity of birds and amphibians, whereas monocultures tend to reduce biodiversity.

Coppice Agroforestry is a great reference for this. It builds on data presented in Edible Forest Gardens textbooks.

Personally I am planting hazels, hybrid poplars, Chinese chestnuts and chinquapin chestnuts, black locusts, and Osage orange. These are not all only for firewood but most of them are intended for resprout-forestry and firewood eventually. Especially the seedling hazelnuts, locust, and Osage orange - what isn't usable for garden construction will go to wood stoves.

Seriously? That's what you're going with? I prefer this tiny ad:
