What is group selection?
The group selection silvicultural system removes small groups of trees from an area of up to a maximum of 0.5 hectares. Over time the management area becomes a multi-aged mosaic of even-aged groups that eventually develops into an uneven-aged forest. The removal of small groups of trees minimizes the visual impact of harvesting, but the resulting canopy openings may be too small to allow enough light for Douglas-fir to regenerate.
