Fig. 3From: Modeling size-density trajectories of even-aged ash (Fraxinus excelsior L.) stands in France. A baseline to assess the impact of Chalara ash diebackObserved and predicted size-density trajectories of the ash stands obtained with the fit of the model defined by Eq. (1) and the constraint of alignment of the inflection points parallel to the maximum size-density line. The plain line is the prediction at the plot level including the random effects due to stand-to-stand variations. The figure does not show any lack of fitBack to article page
