A steamer trunk dating from the late 1890s to early 1900s. Steamer trunks (named after their location of storage in the cabin of a steam ship, or "steamer") which are sometimes referred to as flat-tops, first appeared in the late 1870s, although the greater bulk of them date from the 1880–1920 period. They are distinguished by either their ...
The standard height up the trunk for determining girth is easily measurable and in most trees it is above the majority of the basal flare and gives a fair approximation of the size of the trunk. For the largest trees, or those with a broad basal flare far up the trunk, it would be appropriate to also measure a second girth above the flare and ...
Not all trees have a single trunk, and other single trunk trees pose additional measurement problems because of their size or configuration. The odd forms include those forms that grew because of unusual circumstances that affected the tree, or those trees that simply have an unusual growth form not seen in most other tree species.
Measurement of tree circumference, the tape calibrated to show diameter, at breast height, making sure that the tape is perfectly level and that the tape is not kinked, so as not to skew the reading of the diameter. Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree.
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 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.
A tree is a perennial woody plant. It is most often defined as a woody plant that has many secondary branches supported clear of the ground on a single main stem or trunk with clear apical dominance. A minimum height specification at maturity is cited by some authors, varying from 3 m to 6 m; some authors set a minimum of 10 cm trunk diameter ...
Zelkova serrata is a medium-sized deciduous tree usually growing to 30 m (98 ft) tall. It is characterized by a short trunk dividing into many upright and erect spreading stems forming a broad, round-topped head. The tree grows rapidly when young though the growth rate slows to medium upon middle age and maturity. [5]
