Clear cutting has a similar effect as controlled burning of a forest. True False
zysi [14]

The correct answer is false and here is why:

Clear cutting refers to the cutting of trees, specifically all of the trees in one select area. Replanting is not done and this leads to deforestation.

Clear cutting is a bad thing and controlled burns are a good limiter for a forest.
