Web1. The tree tapers in such a way that the diameter at a point below 4.5 ft is actually smaller than the diameter at 4.5 ft. Measure diameter at the smallest point and record the height at which diameter was measured on the data sheet. 2. Tree has branches or bumps which interfere with DBH measurement. Measure DBH below the branch or bump. WebThe randomly sample d tree s were planted from 2 to 8 9 years ago. Using age or dbh as explanatory variables , parameter s such as dbh , tree height, crown width, crown height, and leaf area responses were modeled using two equations . There was strong correlation (adjusted R 2 > 0.70) for total height, crown diameter, and leaf area with dbh.

WebTree forks at or below DBH . Tree that forks below DBH or near DBH. The measurement is recorded at the narrowest part of the main stem below the fork. The height of the DBH measurement and the fork should be noted (e.g., 3 ft diameter @ 2 ft [Forks @ 4 ft]). Multi-stems 6” or higher above ground level WebJun 3, 2011 · Arborists use DBH (diameter at breast height, or 4.5 feet above the ground) to get above the trunk flare and determine a more accurate measurement of the size of the trunk. Arborists and foresters also measure a lot of trees and it is simply easier (and better for their backs!) to measure the tree at 4.5 feet than at 12 inches above the ground. patrick campagne
