Abstract

The study was conducted at Hon Ba Nature Reserve, Khanh Hoa province, to investigate the biological characteristics of Sindora tonkinensis, a valuable indigenous tree species. Using traditional silvicultural survey and data analysis methods, the research identifies the the species' natural distribution and structural features.. S. tonkinensis is only distributed on the hillsides of mountains with altitudes of 200 – 250 m - in forest evergreen fosrest type, the stems are usually small in diameter of 17 – 30 cm and height of 12 - 13 m. In the research area, sub - area 239 at an altitude of 215 m has the most distributed the species with a density of 30 trees/ha. The average diameter of the speciesin the area ranges at 30.8 cm, height ranges at 13.5 m. The good quality regeneration rate of the species in the evaluated forest status is extremely high (over 80%). S. tonkinensis species in the area exhibited both seed regeneration and shoot regeneration. The findings of this study offered a scientific and practical foundation for the future conservation and sustainable development the species, as well as ensuring the preservation and cultivation of S. tonkinensis population.
