General plot information and characteristics of the understorey plant community.

Plot and understorey properties were obtained from the control and precipitation manipulated subplots for the different exploratories and management types.Species richness = total number of species found on the quadratic area of 2.45 m2, LAIsp = leaf area index and H’ = Shannon’s diversity index; mean values and standard deviation of means are provided (n = 4). Plot Sbu had no understorey vegetation.a S = Schorfheide-Chorin; H = Hainich-Dün; A = Schwäbische Alb; bu = beech, unmanaged; bm = beech, managed; cm = conifer, intensively managed;b According to WRB [49].General plot information and characteristics of the understorey plant community.
