Fig. 4From: Allometric models for above-ground biomass, carbon and nutrient content of wild cherry (Prunus avium L.) trees in agroforestry systemsTree dimension variables. The lines and shaded areas show the bias-corrected regression models with their respective 95% confidence intervals. The dots represent data derived from the QSMs. A Tree height (solid orange line, circles) and crown base height (dashed pink line, triangles). B Crown diameter.
