Fig. 5From: Management breaks the natural productivity-biodiversity relationship in forests and grassland: an opinionGrowth of forests in Germany based on data from the National Forest Inventory (BWI 3: https://www.forstwirtschaft-in-deutschland.de/forstwirtschaft/bwi3/) encompassing 52,263 datasets. The lower vertical line and equation describes the average change of volume increment with tree species number while the upper blue line and equation describes the change of volume increment with tree diversity of the 10 highest values at each level of diversity. Positive numbers indicate an increase in stand volume over the repeated inventory over 10 years, while negative numbers indicate a loss in stand volume, mainly by harvestBack to article page
