Clear Cutting:

Removes all trees, loss of habitat, must manually replace
seeds, and many years to recover/rebuild. Inexpensive
and not as time consuming.

Selective Cutting

Removes only selected trees, maintains habitat,
environmentally friendly, natural regeneration, only a few
years to recover/rebuild. More expensive and time
consuming.
