Fig 10: . Mixed linear model describing the temporal change in P concentrations in leaves of oak stands (Level II) in Lower Saxony. The year 0 on the xaxis equates to 2000. Dark (red) line: overall trend (fixed part of the model), pale (green) line: single plot deviation from the overall trend (random part of the model), circles = observed foliage P concentrations.
