First of all probably most of you already know it, the beginners who don't know, can benefit this way of getting any type of wood.

Trolls are awesome for woodcutting. You just need to eat foods with a good stamina boost, empty your backpack, wear best armour and practice rolling. Be sure to have rested buff on yourself for quick stamina regeneration. Find a troll and lure him to the biome where you want to obtain wood then let the party begin!

Stand near the tree you want to chop and let troll come near you. As soon as he reach melee range and raise his weapon/arm to land a hit, roll back and let it miss you and smash the trees instead. Rinse and repeat.

Bonus if your bring him to a different biome. You can kill other biome's dwellers while softening the troll for killing him after you finish the job. Mining is also possible if the terrain is suitable.

Enjoy!
