Whether a stand is managed with the partial cutting systems (selection or shelterwood) or by clearcutting, regeneration of that stand to desirable species is always a primary objective. The “desirable species” varies from site to site [remember matching species to site to silvicultural system] and may include species that are not particularly valuable from a timber perspective.
Natural regeneration is the method of regeneration for single tree selection. It can also be carried out in some group selection, uniform shelterwood management and even clearcutting scenarios. For instance, after clearcutting an aspen stand, the result will almost always be a healthy, vigorous and dense young stand of aspen.
Artificial regeneration methods may be employed in shelterwood, clearcutting and group selection management. Artificial regeneration usually entails planting a site with 1-2 year old seedlings produced in a tree nursery. It can also be accomplished by aerial seeding the area with collected seed.
