The Importance of Large-Diameter Trees to Forest Structural Heterogeneity

Figure 5

Spatial interactions between large-diameter and small-diameter trees.

Solid black lines show the statistic for the actual pattern, where r is the intertree distance; thin gray lines show curves for 999 patterns simulated by synchronous random torodial shifts of large- and small-diameter tree subpopulations. Positive values of indicate spatial attraction and negative values of indicate spatial repulsion. Large-diameter trees are ≥100 cm dbh; small-diameter trees are <100 cm dbh.
