Factors affecting species richness of tree regeneration in mixed-wood stands of central Maine
Problem Addressed: Within-stand spatial variability and tree regeneration
Goal(s)/Objective(s): Species richness of tree regeneration in response to smallscale ecological gradients, and effect of Abies balsamea abundance on species richness of other tree regeneration
Key Findings: Negative associations with A. balsamea regeneration density; large regeneration and overstorey basal area. Positive associations overstorey basal area; small and large regeneration and canopy transmittance.
Recommendation: Tree species diversity in Acadian mixed-wood stands may not be achievable through the use of gap-harvesting alone if the density of understorey Abies balsamea is not reduced
