Occurrence, morphology and growth of understory saplings in Swedish forests [PDF]
, 2004 Growing demands for a multipurpose forestry leads to increased use of silvicultural systems that avoid clear-cutting. Regeneration in such systems is based on establishment and ingrowth of new seedlings under a more or less closed canopy.
