Individual tree diameter growth modeling system for Dalat pine (Pinus dalatensis Ferré) of the upland mixed tropical forests

•We developed individual tree diameter growth models for Dalat pine.•Weighted non-linear fixed- and mixed-effects models were examined.•Environmental and climatic factors improve reliability of individual tree diameter growth models.•Mixed effect models accounted for the influence of site differences.•Ecological regions, forest canopy, slope, and temperature improved the performance of the model.
