Simplified cylindric volume (assumption stump height = 30 cm, top diameter = DBH from previous inventory) for stumps that resulted from harvested conifer (dashed) and broadleaf tally trees (i.e., a saw-cut was observed). The error bars indicate one standard error of the total volume of stumps of conifer and broadleaf tree species. The data are based on sample plots common to all five NFIs. The data were standardized based on the time period between the measurements of the sample plots in the NFIs 4 and 5 to account for biases due to different interval times between two consecutive NFIs, i.e., on average 10.1 years between NFIs 1 and 2, 10.8 years between NFIs 2 and 3, 8.8 years between NFIs 3 and 4, and 8.7 years between NFIs 4 and 5
