Relationship of Tree Stand Heterogeneity and Forest Naturalness
The aim of our study was to investigate if compositional (tree species richness) andstructural (vertical structure, age-structure, patterns of canopy closure) heterogeneity of the canopylayer is related to individual naturalness criteria and to overall forest naturalness at the stand scale.
