    Definition silvicultural system that involves removal of small groups of trees from an area of up to a maximum of 0.5 ha, which becomes over time a multi-aged mosaic of even-aged groups that eventually develops into an uneven-aged forest Reference "COM-Terminology Coordination, based on: British Columbia. Forestry. 'Group Selection' (26.10.2023)"
    Comment "Basically the group selection system is easier to administer and treat than single tree selection. The simplest types of group selection systems create definite gaps in the forest canopy. These systems fit ecologically with ""gap-regenerated"" stands, which tend to be common in some unmanaged stand types. If gaps are large enough, the entire spectrum of local vegetation may regenerate within them. This may encourage a diverse habitat for wildlife and promote biodiversity."

    Definition "shelterwood system in which small gaps (patches) are created in the stand where adjacent trees can shelter the new regeneration growing in the gaps" Reference "Forestry Blog. 'Shelterwood System: Everything You Need to Know About' (20.10.2023)"
    Comment For example, these openings may comprise 20-40% of the stand area during a given entry. Further cuts expand existing openings or create new openings (see diagram below). The regeneration period for the cutting unit is still concentrated at the beginning of the rotation over 20-30 years, creating an even-aged stand.
