Which of the following is not an effective way to manage forests and trees?

a. planned harvesting

b. planting replacements

c. clearcutting

d. soil maintenance

The correct answer for the question that is being presented above is this one: "c. clearcutting." Clearcutting, clearfelling, or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Clearcutting in itself is not an effective way to manage forests and trees.
