Natural regeneration (luontainen uudistaminen)

After a final felling the forest is either cultivated – which means either sowing or planting – or allowed to regenerate naturally, in the case of seedling felling. In a seedling felling, 50 to 150 seedling trees are left per hectare. The seeds from these trees will grow into a new forest. Once the stand has become stabilised, the seedling trees and shelterwood are removed in a cutting of hold-overs. The first trees to spread naturally onto a felling site are called pioneer trees. In connection with regeneration, the soil is often prepared.
