The Doyle Log Rule, a mathematical formulation, estimates the lumber yield of a standing tree. A instrument using this formulation, whether or not a bodily slide rule or digital software, gives fast estimations based mostly on tree diameter and top. For instance, a hardwood log measuring a particular diameter and merchantable top would yield a board foot quantity estimate based mostly on this established rule.
This estimation methodology facilitates fast timber appraisal, aiding in forestry administration and the shopping for and promoting of timber. Developed within the mid-Nineteenth century, it has develop into a normal, although its accuracy is debated and different scales exist. Understanding its limitations is essential for correct valuations, significantly with smaller diameter timber the place it tends to underestimate yield. This historic context and sensible software spotlight its ongoing relevance within the trendy lumber trade.
