Master tree diameter at breast height (DBH) measurement protocols for standard boles and complex field anomalies. A single measurement error can distort timber cruises, tree inventory data, and forest carbon accounting by thousands of dollars. This comprehensive video guide breaks down industry-standard tree mensuration protocols: establishing the 4.5 ft (1.37 m) baseline, using diameter tapes (d-tapes) and calipers, and properly measuring non-standard trees including slopes, leans, burls, buttress flares, multi-stem forks, raised planters, and fallen timber.
