Figure 4

A comparison between the predicted f from the stand-level model based on Equation 2 and the earlier version of this stand-level model described by Forrester ([2014]), which required an empirical parameter that is difficult to calculate for some crown architectures. The data correspond to (a) Stand 1, (b) Stand 2, (c) Stand 3, (d) Stand 4, and (e) Stand 5 in Table 1. The solid lines are 1:1 lines and the dashed lines are lines fitted to the data that pass through the origin. The relationships did not differ depending on whether the mixtures or monocultures were used, so for stands containing mixtures (b-e) the figure only contains data from the mixtures.
