Modeling Dominant Height Growth in Planted Pinus pinea Stands in Northwest of Tunisia

Figure 10

Site index curves (site index values of 6, 9, 12, and 15 m at reference age of 30 years) (Lundqvist-Korf: GADA) overlaid on the trajectories of the observed dominant heights over time for Pinus pinea in northwest of Tunisia, superposed with national site index curves (Bailey-Clutter: ADA) for Pinus pinea in Spain [1] and site index curves (Bailey-Clutter: ADA) for Pinus pinea in Catalonia [2] both with site index values of 9, 13, 17, and 21 m at reference age of 100 years.
