The base of a Yellow Birch trunk. In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
Tree girth measurement diagram. Tree girth is a measurement of the circumference of tree trunk. It is one of the most ancient, quickest, and simplest of foresters' measures of size and records of growth of living and standing trees. The methods and equipment have been standardized differently in different countries.
Tree volume is one of many parameters that are measured to document the size of individual trees. Tree volume measurements serve a variety of purposes, some economic, some scientific, and some for sporting competitions. Measurements may include just the volume of the trunk, or the volume of the trunk and the branches depending on the detail ...
The girth of a tree is usually much easier to measure than the height, as it is a simple matter of stretching a tape round the trunk, and pulling it taut to find the circumference. Despite this, UK tree author Alan Mitchell made the following comment about measurements of yew trees: The aberrations of past measurements of yews are beyond belief.
Most champion tree programs focus finding and measuring the largest single-trunk example of each species. There are three basic parameters commonly measured to characterize the size of a single trunk tree: tree height measurement, tree girth measurement, and tree crown measurement. Foresters also perform tree volume measurements.
Sperry said, “If a pecan tree is free-standing, that is, not touching other trees, power lines, etc., you can put a sheet metal collar in place around its trunk.”
A tree typically has many secondary branches supported clear of the ground by the trunk, which typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees the trunk is surrounded by a layer of bark which serves as a protective barrier.
Pruning a fig tree annually is the gardener's secret to maintaining a happy and healthy tree. It promotes fruit production and new growth, keeps the tree at a manageable size, and enhances overall ...
