Calculating tree age from dbh
WebOur study focuses on street trees that fork between 30 and 137 cm of height (hereafter "multi-stemmed trees"), which researchers have identified as particularly challenging in the ongoing development of urban allometric models, as well as consistency in measurements across space and time. Webestimate defect on a per log basis and convert to apercent age of the tree. Prorate average scaling cull percent to the tree’s visible defect percentage. Example: Douglas-fir has velvet top conk on the ground (root). The deduction is 1/2 of the butt log (sec. 22.31b). The tree is 130feet HT x 30 inches DBH. Exhibit 01 shows that a 130foot
