Even aged high forest

Conventional silviculture consisting of even aged stands of trees

Silvicultural system Rotation length Regeneration method Thinning Felling Notes
Clear fell/clear cut Depends on species; a minimum of 40-60 years, but may be longer than 160 years for slow growing species such as oak Usually planting on larger areas, may use natural regeneration from seed on smaller areas May take place throughout the lifetime of the crop. Thinning may be systematic (eg every third tree) or selective (eg the 20% of trees with the poorest form) The crop is cleared by a single felling at the end of the rotation There is a grey area between a heavy thinning of a forest stand, and some of the systematic regeneration methods described below
