PINASTER

PINASTER is an individual tree level empirical model developed for maritime pine even-aged stands in Portugal. The model is mostly based on Nunes (2011) PhD research and has been completed with results form other research. PINASTER integrates modules for the  initialization of stands, growth prediction, additional calculus and thinning simulation:

Prediction Module:

• Site index curves (Tomé et al. 2001)
• Diameter growth  (Nunes et al. 2011)
• Tree survival (Nunes et al. 2011)

Calculus module:

• Height-diameter curves (Tomé et al. 2007)
• Self-thinning (Tomé 2001)
• System of equations for total standing volumes and volume by assortments (Nunes et al. 2010)
• Total biomass and biomass by tree components (Faias 2009)
