DBH
DBH (Diameter at Breast Height) is a standard way of measuring tree size in forestry. It's like taking a tree's waist measurement at about 4.5 feet (1.37 meters) above the ground. This measurement helps forestry professionals figure out how much wood is in a tree, how old it might be, and its overall health. Think of it as a vital statistic, like height and weight for humans, that helps foresters make decisions about forest management. When you see DBH in a resume or job description, it shows that the person knows how to properly measure and assess trees, which is a fundamental skill in forestry.
Examples in Resumes

Expected Answer: Should describe approaches for measuring multi-stemmed trees, trees with buttresses, or trees on steep slopes.
Junior Level Questions
Q: What is DBH and how is it measured?
Expected Answer: Should explain that DBH is measured at 4.5 feet above ground level and describe basic measurement techniques using diameter tape or calipers.
Q: Why is DBH an important measurement in forestry?
Expected Answer: Should explain how DBH helps determine tree volume, growth, and forest inventory basics.
