>>866410Cutting trees down is both needlessly destructive, and also yields bad fire wood. The reason for the bad wood, is because live trees are very wet on the inside, as they feed water through all the wood to the leaves or branches.
What you want to use for firewood is "dead standing wood" trees that have fallen over, or even old logs that are elevated off the ground will give you the best fire wood, and will often times be dry on the inside, even under rainy/wet conditions. Try to avoid saturated branches and logs laying directly on the ground, as these will be wet, and burn cold and smokey, if at all.
It is better practice to burn wood found in the area you are camping, as bringing wood in from an outside location can introduce new bacteria and insects to an environment that wouldn't other wise have it. Also, medium to large size branches do just fine. You don't need big logs split up like your pic related.
Tl;Dr, find a fallen over tree, and cut that up for your fire wood
