Figure 6


Sensitivity of optimal closure (c) and optimal relative net increment (RNI, net increment – net increment of closed stands, at the same mean tree biomass) for intervals, starting to the left in the figure, for q (=1 to 0.08, dashed line), γg (= 4 to 1.5, solid line) and γm (=1.8 to 8.6 dotted line). The parameter intervals correspond to the range of estimated values (Tab. II). Baseline parameter values: q = 0.2, γg = 3.5, γm = 4, α = − 1.75, corresponding to the values for all species combined, expect for the slightly lower value of α.
