| সারসংক্ষেপ≠ | Tree height measurement—determining the vertical distance from ground to tree top—is a cornerstone of forest inventory and biomass estimation. Ranging from classical optical instruments (clinometer, Abney level) to modern laser hypsometers and airborne LiDAR, tree height quantification enables calculation of volume, biomass, site index (productivity), and forest structural characterization essential for management, research, and carbon accounting. | Allometric equations predict tree above-ground or total biomass from easily measured tree dimensions—typically diameter at breast height (DBH), height, and wood density. Grounded in biological allometry (scaling laws) and codified by Chave, Niklas, and others, allometric equations are essential tools for rapid biomass assessment without tree harvesting. Used globally for carbon accounting, yield estimation, and ecosystem characterization. |
