dendrometric

Dendrometric refers to the measurement of trees and their structures. It is closely aligned with forest mensuration and dendrometry, the latter sometimes used to describe the methods and data associated with tree measurement. The term derives from Greek dendron 'tree' and metron 'measure'.

Typical dendrometric variables include diameter at breast height (DBH), total tree height, crown width and crown area, bole height, volume or biomass estimates, and taper along the stem. These variables are collected for standing trees in forest inventories or research plots. Measurements are taken using field instruments such as diameter tapes, calipers for small diameters, relascope, prism or laser devices for height; clinometers or hypsometers; laser rangefinders and LiDAR for stature and crown metrics. When direct measurement is impractical, allometric or taper equations estimate volume or biomass from DBH and height.

Applications include forest management planning, growth and yield modelling, carbon accounting, timber valuation, and ecological or climate research. Dendrometric data feed models of species-specific growth, allometric relationships, and remote sensing calibration.

Challenges include measurement error, procedural inconsistencies, seasonal variation in measurements, and species-specific differences. Standardized protocols and training help ensure comparability across plots; increasingly, remote sensing technologies extend dendrometric assessment to larger areas.
