Fig. 25From: Under storm risk, economic productivity of Norway spruce (Picea abies (L.) H. Karst) in monoculture shows sharper decline than in mixture with European beech (Fagus sylvatica L.)No thinning. The above graphs show mean DBH (diameter at breast height, y-axis) vs. stand age (x-axis) simulations for beech, comparing the growth in monoculture (black) with its growth in mixture (blue) with another species (red)Back to article page
