Preliminary height models, a volume model, a site index model and a survival analysis for
Pinus halepensis
Mill. in Chalkidiki (Northern Greece) were preliminarily developed based on measurements of 20
experimental plots established in 2010. The data for the height, volume and ‘mortality’ models consisted
of 790 observations taken from 40 trees (20 dominant and 20 co-dominant). An equation derived from the
hyperbolic function was selected to model the dominant height and the volume development. The height
growth model was used as a guide curve to develop two site index curves. Mean dominant and codominant
height was estimated at 10m (site I) and 7m (site II) (base age of 17 years). Kaplan-Meier survival and
hazard functions applied for the ‘mortality’ analysis, confirmed the site index curves developed from the
height model (SI10 and SI7).
