It takes 15 years to grow a pine (the fastest burning wood) to cutting stage.
You can expect aproximately 10-12 cords of a 15 ft tree.
How many cords of wood do you need to heat your living winter area for one week.
Oak trees burn longer than pine.
And take about 20 years to cutting stage and you can expect to get approximately 17- 25 cords of a 17 ft oak tree.
Again, how many cords of oak do you need to heat your living winter area for one week.
Then consider your topical view or number of trees you already have that may be anywhere from 25-100 years old.
Guaranteed. You may not cut down trees indiscriminately.
There are more aspects to consider.
Stump removal so you can plant new. (Who wants a field of stumps?)
Land erosion.
And loss of the rain forest effect that enhances better weather.
Undergrowth for small animals to burrow down and food for the carnivorous wild animals in the forests and vegetation if the trees are not too close together (wild berries, wild herbs, etc.).
