Black dots indicate forests dominated by common beech (F. sylvatica), gray dots are dominated by oaks (Quercus sp.), and white dots are dominated by Norway spruce (P. abies). Each forest is divided into one to four plots, each having several inventories through time (see Table 1). A few major cities are indicated in gray in italics
