Driving mechanisms of productivity stability vary with selective harvesting intensities in a mixed broad-leaved Korean pine forest

Abstract Key message We found that the stabilizing mechanisms for forest productivity varied across harvesting intensities in a mixed broad-leaved Korean pine forest. Effects of overyielding at high species richness and asynchrony occurred only unharvested lightly harvested plots, whereas asymmetries between individuals different size contributed significantly to when harvestings became intensive. Context Understanding driving factors ecosystem stability has become increasingly crucial management. However, it remains unclear whether how might be influenced by management practices. Aims related temporal aboveground biomass history. further tested three key modulated selective intensities. Methods Based on 10-year monitoring (five repeated tree inventories) Northeastern China recovering from harvesting, we examined relative importance two diversity-dependent (overyielding asynchrony) one size-dependent mechanism (asymmetric growth) wide range (0–73.4% basal area removed). Results lowered stability, asynchrony, growth dominance coefficient. Growth coefficient had an overall stronger effect than asynchrony. Moreover, strengths intensities: effects were detected explanatory power outweighed diversity-related variables Conclusions emphasized consider both diversity- size-related as potential productivity. In fact, is partitioned among trees well sizes may co-determine response disturbances.
