From: How much timber from Norway spruce (Picea abies L.) is left on the harvesting site as treetops? A study on scaling and grading yields of harvesters

Fig. 3

Visualisation of the post-hoc analysis for losses (−) or surpluses (+) of the volume of timber compared to the full stem volume in particular tree diameter classes. The stem diameter class is the central value of a stem diameter interval at breast height (e.g., stem diameter class 10 relates to diameters at breast height of 9.1 to 11.0 cm)
