Mean shrub height, crown volume, total standing biomass, and biomass of leaves, and coarse and fine materials, increased rapidly during the first 10 years after management, but then converged slowly to a plateau that was not reached within the chronosequence.
This means, in relation with the findings concerning crown volume that smaller crowns have a higher crown volume increment in GYO651 but not yet in SAN653.
The horizontal heterogeneity λ h is calculated as a function of mean midday solar zenith angle, k H, the ratio of mean tree leaf area (L A ) to mean tree crown surface area (S A ) and v frac, which is the sum of the crown volume (m3) of all crowns within a given layer within one hectare divided by the total volume of that layer (m3) over one hectare.
Under the specific environmental conditions of an open landscape, high values of crown volume were recorded not only for the thickest trees but also for trees with diameters oscillating around the mean values of this parameter.
Crown volume cv was calculated by multiplying csa and cl.
Crown width might increase on the expense of crown length, but the combination of both keeps the scaling of the crown volume rather stable.
Mean crown height, which is the average green crown height for the trees measured, was also calculated.
Graphical illustration of the non-linear smoothers f 1 − f 3 from eq. 4 for crown length (upper panel), crown cross section area (middle panel), and crown volume (lower panel) as the dependent variable.
A statistically significant relationship was found between crown volume and diameter at breast height.
However, D. cuppressinum alone accounted for 72% of basal area and 75% of crown volume.
