Abstract : In regions lacking access to advanced technologies, conventional (destructive) wood density estimation methods remain prevalent. This study assesses the viability of a more accessible and less destructive approach using a handheld increment borer. A hundred core samples were collected from ten tropical tree species at 1.3 m above the ground using an auger corer. For conventional methods, wood specimens (8 cm³) underwent oven drying at 105 °C until reaching a constant weight. Results from the oven-drying method significantly differed (p < 0.001) from the water displacement and increment borer methods. Although not statistically significant, increment borer method density values slightly surpassed those of the displacement method (0.75 g cm⁻³ compared to 0.73 g cm⁻³). It is essential to note that the water displacement method is inherently destructive. Consequently, the increment borer method emerges as a promising alternative, particularly in regions with limited access to modern wood density extraction tools, offering a practical and less invasive solution for comprehensive assessments.
