A tropical tree-ring study is presented using 36 specimens of Cariniana estrellensis from the Mata Atlântica Biome within the State of São Paulo: Caetetus and Carlos Botelho. We aimed to assess the suitability of this species for chronology building, as well as for dendroclimatological studies, with the help of its lifetime growth trajectories. Cariniana estrellensis forms visible tree rings with a dense sequence of parenchyma bands at the end of the latewood, followed by a relatively distant sequence of parenchyma bands in the subsequent early wood of a tree ring. However, it was impossible to establish a chronology, solely by tree-ring width measurements and crossdating, for a number of reasons, including sequences of problematic wood anatomy, abundance of wedging rings and probably missing rings. Therefore, building a robust chronology for this species requires a multi-parameter approach, however, no experience is currently available. Therefore, to reveal possible climate-growth relationships for Cariniana estrellensis at both sites, we tested to correlation analyses of microclimatic conditions with tree growth and investigated patterns of lifetime growth trajectories. Annual precipitation is over 1300 mm at both sites, with the dry season primarily between June and August. Both sites showed clear differences in their microclimatic regime and topography. 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
