Overall, light availability is the most likely crucial factor for the studied species. A significantly lower photosynthetic active radiation and daily photoperiod was found at Carlos Botelho by the strong influence of orographic rainfall, foggy conditions and shade caused by the adjacent mountain chain. Consequently, trees at this site generally showed a lower average annual growth rate as compared to the Caetetus site with differences between juvenile and mature growth phases remaining nearly constant throughout their lives. In contrast, trees from Caetetus had less consistent growth phases, with increased growth after the juvenile growth phase. Thus, it can be concluded that dendroclimatological studies using growth characteristics have the potential to clarify the generally complex stand dynamics of Cariniana estrellensis. However, the development of tree-ring chronologies, based on tree-ring width analyses of cores or discs is nearly impossible.
