Sampling strategy: Trees were selected to cover a range in size and dominance classes, from a number of stands ranging in altitude from 400 to 1800 m asl.
Leaf area: Methods unknown.
Stem cross sectional area: DBH (measured by individual).
Height: Unknown (measured by individual).
Biomass: Branch biomass was converted from fresh weight and water content as provided in the publication.
Growth environment: Even-aged plantations, 'gleichaltrigen Hochwald'.
This is how the study Burger1953 fits in the entire dataset (grey). each colour represents a species. A legend of species names with colours is included at the end for reports with 1 < n < 20 species.
