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.
The tree is occasionally nicknamed the "Tree of Life" from the images of animals that are reputedly visible in the tree's gnarled trunk. As part of an official project local schoolchildren give tourists a tour of the tree and point out shapes of creatures on the trunk, including jaguars and elephants. [citation needed]
A transverse section through a tree trunk or a horizontal core will show concentric circles of lighter or darker wood – tree rings. [68] These rings are the annual growth rings [69] [70] There may also be rays running at right angles to growth rings. These are vascular rays which are thin sheets of living tissue permeating the wood. [68]
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.
Melaleuca quinquenervia, commonly known as the broad-leaved paperbark, paper bark tea tree, punk tree or niaouli, is a small- to medium-sized tree of the myrtle family, Myrtaceae. It grows as a spreading tree up to 20 m (70 ft) tall, with its trunk covered by a white, beige and grey thick papery bark.
The tree has survived for so long due to vegetative cloning. The visible tree is relatively young, but it is part of an older root system that dates back millennia. The trunk of the tree may die and regrow multiple times, but the tree's root system remains intact and in turn sprouts another trunk.
