Recently, increasing attention has been paid to the anthropogenic degradation of the riverbed and its relationship to the ecological status of the adjacent river landscape. The key objective of this r...
Importance of stand structure and neighborhood in European beech regeneration
Fagus sylvatica Seedlings Saplings Closed canopy Ontogeny Competition Understory
2024/3/8
The European beech (Fagus sylvatica L.) is a competitive and shade-tolerant species, with its natural regeneration in closed-canopy stands affected by a number of variables. The study aimed to identif...
Crown development of beech crop trees under different thinning regimes
