| Tóm tắt≠ | Stand basal area is a fundamental forest mensuration metric representing the total cross-sectional area of tree stems per unit land area, typically expressed in square meters per hectare. Formalized across twentieth-century forestry literature (notably by Husch, Beers, and Kershaw), basal area serves as a key indicator of forest density, biomass accumulation, and competitive pressure, essential for yield prediction and stand management planning. | 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. |
